The invention of this patent includes English/Spanish translator to leverage relevant sides of the brain for the desired effect. The present inventive device focus is on the content and the production, post production to achieve the same cognitive effects vs. manipulating/controlling the binaural signal. 
     “Method and Apparatus for Generating 3D Audio Positioning Using Dynamically Optimized Audio 3D Space Perception Cues” U.S. Pat. No. 8,755,432 from Jun. 17, 2014 is an invention for the preparation of digital 3D movies for release in one format it does not include an efficient conversion of the audio component that insures the presence or preservation of the 3D space perception audio cues. This invention pertains to a method and apparatus of enhancing a 3D movie by using 3D space information associated with at least some of the characters/objects that are either part of the scene or off scene during the preparation of a digital 3D movie. Its audio component may not include clear 3D space perception cues, either because these cues have been stripped away or because they were missing. This patent is not directly relevant to the present invention. 
     “Method and System for Up Mixing Audio to Generate 3D Audio” U.S. Pat. No. 9,094,771 from Jul. 28, 2015 is a coding method which extracts parts of an existing 2D audio program to generate an upmixed 3D audio program which when rendered by speakers is perceived as having depth effects. The goal is to generate 3D audio through speakers at different distances from the listener to aid visual reference and/or be stimulated by “stereoscopic 3D video programs.” The invention of this patent is not directly related to the present inventive device. 
     “System and Tools for Enhanced 3D Audio Authoring and Rendering” U.S. Pat.

Refers to tools that create metadata for audio objects, specifically speaker zones and layout. The invention of this patent does not mention the use of perspective switching. 
     “System and Tools for Enhanced 3D Audio Authoring and Rendering” U.S. Pat. No. 9,549,275 from Jan. 17, 2017 is essentially the same as U.S. Pat. No. 9,204,236. 
     “System and Method for Producing Had Externalized 3D Audio Through Headphones” U.S. Pat. No. 9,560,464 from Jan. 31, 2017 essentially relates to 3D technology inserted into headphones, using filters, crosstalk cancellation. Input is any kind of audio and pretends to translate into a 3D representation. The present invention has input that is audio that has been created using sources and tools that generate binaural and 3D environments. We do not use any specific technology for the headphones. No mention of perspective switching. 
     “Implementation Method Of 3D Audio” Pat. App. US 2003/0202665 published Oct. 30, 2003 uses head related transfer function to synthesize binaural sound from a monoaural source. This again, is applying an audio algorithm to regular sound to make it sound like binaural. This invention could be used inside headphones to convert regular monoaural sound into binaural sound. The present invention uses headphones and perspective switching. 
     “Decoding of Binaural Audio Signals” Pat. App. US 2007/0160218 published Jul. 12, 2007 is an invention that applies a predetermined set of head-related transfer function filters to a plurality of audio channels. Refers particularly to decoding of binaural audio signals to simulate in many audio sources. The key difference between &#39;218 and the present invention is that this invention has nothing to do with headphone delivery. &#39;218 appears to refer to how to simulate 3D sound using multiple audio channels or sources. No perspective switching. 
     “Apparatus and Method for Processing 3D Audio Signal Based on Hrtf, And Highly Realistic Multimedia Playing System Using the Same” Pat. App. US 2011/0150098 from Jun. 23, 2011 is hardware that decodes audio data to translate it into 3D data. The key between the present invention and difference that of &#39;098 is that &#39;098 refers to a binaural microphone but not to the content per se. &#39;098 neither mentions, headphone delivery nor perspective switching. 
     “Binaural Audio Systems and Methods” Pat. App. US 2015/0296288 from Oct. 15, 2015 is related to audio information that can be stored in a mobile device to sync up with a speaker-like device. Refers to the ability to experience movies in different languages via headphones. The above patent application refers to the storage of binaural audio, not the creation of binaural/3D content. The above patent application has not much to do with the audio per se, but rather the delivery of specific audio. The above patent application does not refer to perspective switching. 
     “Binaural Audio Processing” Pat. App. US 2015/0350801 refers to an audio renderer and processor of head related binaural transfer function data. This application has no mention of headphone delivery or perspective switching. 
     “Passive Audio Headset Compatible with Binaural Recording and Off-Headset Noise Cancellation” Pat. App. US 2016/0373861 refers to the headset, and specific functions for binaural recording and noise cancellation. This application does not relate to the creation of binaural content and mixing.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Before explaining the present apparatus in detail, it is to be understood that the apparatus is not limited to the particular embodiments and that it can be practiced or carried out in various ways. 
     While most of the terms used herein will be recognizable to those of ordinary skill in the art, it should be understood, however, that when not explicitly defined, terms should be interpreted as adopting a meaning presently accepted by those of ordinary skill in the art. In cases where the construction of a term would render it meaningless or essentially meaningless, the definition should be taken from Webster&#39;s Dictionary, 11th Edition, 2008. Definitions and/or interpretations should not be incorporated from other patent applications, patents, or publications, related or not, unless specifically stated in this specification or if the incorporation is necessary for maintaining validity. Specifically, defined terms: 
     The term “binaural audio recording” as used herein can refer to auditory illusion perceived when different pure-tone waves, with different frequencies, are presented to a listener dichotically, that is one through each ear, but with simultaneous stimulation of both ears with the same stimulus. The inequality of the two impressions determines the correct direction and distance of the sound. The binaural audio recording is a 3D audio recording, a holophonic recording, a holo-acoustic recording, and virtual reality sound. The term “binaural audio recording” can refer to a recoding that includes the script, but supplemental information as well, such as an interview with a conductor, the history of a musician, a physician endorsement, a voice over that is not included in the script, and bloopers. 
     The term “audio recording” as used herein can refer to any audio materials, including music, instructions, educational materials, books, pod casts, magazines, novels, instructional, manuals, self-development and improvement materials, reference manuals, and any other types of literature with a beginning, middle and end to each spoken section, which can be streamed from an online source or downloaded onto a data storage device. 
     The term “marked locations” as used herein can refer to marked sections of audio pieces. 
     The term “dialog” as used herein can refer to the words spoken by voice actors, including voice effects. 
     The term “holophonic sound effect” as used herein can refer to sound effects recorded, which take into account natural ear spacing or “head shadow” of the head and ears. Natural ear spacing can enable holophonic sound effects to cause a listener to generate interaural time differences and interaural level differences simultaneously. For example, a car motor moving from left to right while indicating (i) how high from the ground the car can be located relative to the listener, (ii) how far the car is from the listener, and (iii) a location of the car relative to the listener, through the binaural sound recording there can be a holophonic sound effect. 
     The terms “menu listing names” as used herein can refer to a display featuring a title of the audio recording, a call to action, such as “click to select character” a plurality of actuation buttons or icons enabling a listener to click or select a button, an image of a principal character, or audio passage associated with the actuation button, and an identifier that is associated with the principal character, such as a name or a description. 
     The term “menu of audio recordings” as used herein can refer to a display screen presenting a plurality of visual icons to a listener. 
     The term “narration by a voice over” as used herein can refer to words spoken by voice over to guide the listener through the story or to provide context to the story. 
     The term “non-holophonic sound effects” as used herein can refer to sound effects, which do not take into account natural ear spacing or head shadow of the head and ears. 
     The term “playback” as used herein can refer to the reproduction of an audio piece, or audio story that has a title, a beginning, a middle and an end. In embodiments, the audio story or audio recording can have chapters. 
     The term “visual icon” as used herein can refer to a title, an author&#39;s name, and an image that reflects characteristics of contents of the audio recording. 
     The term “script” as used herein can refer to a series of at least one of: sounds and words that could be sequential or at the same time, which together creates an expression that can teach, provide mental health therapy, safety training, provide a narrative, and/or strengthen cognitive skills of a listener. 
     The term “visual image” as used herein can refer to at least one of: a static image or a video image, including black and white or color video, photographs, graphic images, paintings, animations, cartoons, ultrasound images, infrared images, x-rays, sonograms, 3D and 2D images, computer generated simulations of 3D images or environments, and drawings. 
     The term “headphones”, “wearable headgear” or “ear buds” as used herein can refer to any listening device utilized to transmit sounds into a user&#39;s ear(s).

     By another example, a system is providing a playback of a binaural audio recording of Romeo and Juliet for Maria to hear. In this embodiment, Maria downloads an app from a specific online app store via the internet to her smart phone. In this embodiment, the software app includes computer instructions that instruct Maria&#39;s smart phone to download or stream binaural audio recordings from a data storage, such as an online store or an administrative data storage connected via a network. In several embodiments, the computer instructions enable Maria to simply click on a recording icon presented on her listener personal computing device  22  through a menu. In some embodiments, the computer instructions enable Maria to control playback of a selected binaural recording using navigation buttons and perspective switching buttons presented on the personal computing device  22 . 
     In some embodiments, the software app provides navigational buttons and other buttons to select the Romeo and Juliet binaural audio recording and control the playback into her earbuds. In some embodiments, the inventive device, stores a plurality of binaural audio recordings in the data storage of the online store. Each binaural audio recording has a recording icon connected to a script of a binaural audio recording. 
     In several embodiments, for Romeo and Juliet, the recording icon is a picture of a man and a woman in 13th century clothing. Maria picks the picture of the man and woman and downloads or streams the binaural audio recording to her smart phone. In several embodiments, on her smart phone, Maria sees a first individual audio source button titled “Juliet” and a second individual audio source button titled “Romeo” and a third individual audio source button titled “Spectator”. Each individual audio source button activates an audio source for playback for as long as that individual has a role in the playback being presented on the binaural audio recording. For example, in this case, Romeo&#39;s playback would end before the actual ending of the play. 
     In several embodiments, Maria inserts a pair of earbuds, which can be wearable headgear into her ears to receive the playback of Romeo and Juliet. The earbuds provide a first audio output into her left ear that is different from the second audio output into her right ear. Once Maria picks the Juliet button, the binaural audio recording starts the playback. In this example, instructions on how to start the playback of the binaural recording, including instructions on how to click a navigation button, and close eyes can be provided. 
     In several embodiments, while Maria listens to Juliet telling the story from her context, (on a second floor) from her perspective using her lines, a perspective switching button appears on the display of the smart phone. Once that perspective switching button is activated, non-selected individual audio sources of Romeo or Spectator can be presented to Maria for selection any time during the playback 10 from Juliet&#39;s individual audio source. In several embodiments, continuously during the playback, a plurality of navigation buttons can be displayed enabling Maria to move through the binaural audio recording. At lunchtime, Maria selects the “pause button” to stop the binaural audio recording and mark a location in the script enabling Maria to return to the playback marked location in the script after lunch. In some embodiments, after lunch, Maria returns to the playback and decides to select “Spectator” and hears the remainder of the story from the perspective of the “Spectator.” 
     In another example embodiment of one aspect of the present invention. Jose who is blind, decides to listen to a binaural audio recording. Jose wants to hear a concert from various instrument perspectives because he is an aspiring conductor. In this embodiment, Jose puts on his wearable headgear, headphones, with a processor and data storage and Bluetooth connectivity to receive playback and provide a first audio output and a second audio output to his ears. In this embodiment, his listener personal computing device, Jose uses the processor and data storage mounted in the headphones to control playback to the wearable headgear. 
     In several embodiments, Jose connects to a computer processor via the Internet to download or stream computer instructions into the processor in his headphones that enable him to download or stream binaural audio recordings by using voice activation and voice control software. The voice activation software enables Jose to solely control playback with the wearable device. In many embodiments, the wearable device is compatible with any downloadable or streaming playback. 
     In several embodiments, Jose&#39;s headphones include a microphone connected to the personal computing device processor for detecting audio commands from Jose and triggering at least one of the recording icons in data storage connected to an online app store. In this case, Jose simply says “Play the Conga Line” and the voice recognition software in the data storage connects Jose to the correct binaural audio recording. In several embodiments, the voice recognition software can enable Jose to control the playback of the binaural audio recording including selection of a perspective by vocally engaging the perspective switching button and vocally engaging one or more of the plurality of navigation buttons enabling a listener to control the playback feature. 
     In several embodiments, Jose&#39;s personal computing device connects to a computer processor via the internet that has a data storage with many binaural recordings to select from and download or stream and enjoy. Jose can decide to select the trumpet from “Play Conga Line” as his first individual audio source. About 10 minutes into the playback, Jose decides he wants to hear the song from the perspective of the drums. Jose speaks “Activate perspective switching.” The software speaks the non-selected individual audio sources which include “drums” into a speaker of the listener personal comping device that Jose hears. Jose then says the words “drums”. The binaural audio recording then continues playback from the drum player&#39;s perspective. 
     In several embodiments, the listener&#39;s personal computing device  22  can be affixed to the wearable headgear. In some embodiments, the script can be a music score and the individual audio sources of the script can be instruments presenting a portion of the music score or an individual audio source can be from the perspective of the audience viewing the presentation of the music score.

       FIG. 7  illustrates one embodiment of the present invention in which a user  2000  is shown graphically in relationship to a variety of potential sound input locations. The ability to perceive sound direction works through a process known as binaural hearing, which essentially means “hearing with two ears”. The key element to binaural hearing is the location of the ears and altered by the elements and details that affect how the sound is picked up: the size and shape of the head, its surroundings and their composition, distance; among others. Additionally, because the ears are on opposite sides of the head, the sounds heard by either ear will vary in timing, volume, and frequency balance. These differences are the clues the brain uses to decode a sound&#39;s location. If we want to create audio illusions, we must understand and mimic how the ears interpret information to trick them and have them work with the brain toward the desired objective. 
     Generally, the brain interprets each audio stimuli as follows: Variations in Timing—When a sound comes from the left, the travel distance to the left ear is-slightly shorter than the travel distance to the right ear. So, the left ear hears it milliseconds before the right. That&#39;s the brain&#39;s first signal that the sound might be coming from the left. Variations in Volume-Sound gets softer as it moves further away. Sound also gets softer when there are objects blocking it. If the unidentified sound is coming from the left . . . . It will also sound a tiny bit softer to the right ear since it&#39;s further away. And it will sound softer still, since the head is blocking it. Variations in Frequency—When a sound comes from the left, the head blocks a portion of it from reaching the right ear. However, it doesn&#39;t block all frequencies equally. High frequencies have less energy, are more easily absorbed by obstructions than low frequencies. So, with the unidentified sound, the right ear will get more of the low end, and less of the high-end frequencies. 
     When all timing, volume and frequency combine, the brain identifies what it hears. Because in nature, these 3 elements always line up. If the sound is directly in front of a person: The timing would be the same in each ear. The volume would be the same. The frequency would be the same. And the same would also be true if the sound were directly behind a person. 
     Distance: When the brain judges the distance of a sound, it relies less on binaural hearing, and more on the following considerations: the frequency response, the amount of reverb, and the amount of pre-delay. Amount of Reverb—The farther the sound, the more reverb it has. That “reverby” character of far-off sounds exists because almost none of the sound reaches a person directly. Instead, almost all of it reflects off multiple surfaces before ever reaching the ears. That is the brain&#39;s first notice that a sound is far away. Pre delay- Pre-delay is the time gap between the first arrival of direct sound, and the first arrival of reflected sound. In an environment with lots of reflective surfaces, sounds heard from up close may still have a lot of reverb, but the time gap between the directed sound and reverb will be large. Far-off sounds have a shorter pre-delay time, because both sounds must travel a great distance to reach the person. Frequency Response—When a sound travels far to reach a person, much of its high frequency detail dissipates along the way. High frequencies carry less energy than low ones, so they are more easily absorbed by objects in the environment. Over long distances, obstructions such as land masses, buildings, and even air in the atmosphere all contribute to squash those high frequencies. When all these sound elements align, the ears and the brain connect and process all the information to identify what is being heard. 
     Binaural recordings utilize frequency, pre-delay, reverb, volume and timing, to generate different audio effects than mono recordings. 
       FIG. 8  illustrates one embodiment of content creation of binaural content. The perspective spatial 3D audio effect is created by recording (through single/stereo/microphones, or 3D microphones with ear-like cavities or holophones; among others) audio stimuli (voices, sound effects (“SFX”), instruments—anything that generates sound) directly into suitable formats for multi-channel or binaural reproduction. Or the spatial effect can be created artificially in any two/multi-channel audio signal. Monoaural audio recording  5000  can be created with human voice  3010 , musical instrument  3015 , machine  3020 , and any kind of SFX  3025 . Binaural audio recording  4000  can be created with human voice  2010 , musical instrument  2015 , machine  2020 , and any kind of SFX  2025 . 
       FIG. 9  illustrates one embodiment of the present invention as an example of music score/concert. As shown, a binaural audio recording of the music band The Dudes, where the script is their hit song “Today”, and the sources for playing back the script are Jeff (vocals)  2110 , Roger (drums)  2105 , George (guitar)  2115  and Audience  2120 . The listeners, through their personal computing device (smartphone screen), are able to select which script they want to listen to and from which source&#39;s perspective Jeff, Roger, George, or Audience. 
     In several embodiments, if the listener selects source  1 , the playback of the binaural audio recording will be from Jeffs perspective  2110 , which means that the listener will “become” the lead vocal in the script, with source (drums)  2105  sound coming from back-right, source (guitar)  2115  sounds coming from side-left, and source (audience)  2120  sound coming from far-front. 
       FIG. 10  illustrated one embodiment of the present invention using “Machinery.” In this embodiment, a binaural audio recording of the plastic bottle-building machine at the soda bottling facility, where the script  2220  are the sounds stemming from the process (plastic injection  2205 , bottle contouring  2210 , plastic freezing  2215 , end product exit  2220 ), and the sources are the different parts of the machine (injectors, molds, freeze hose, conveyor belt). 
     In several embodiments, if the listeners are maintenance workers in training who, through their personal computing device (smartphone screen), are able to select from which source&#39;s perspective (injectors  2205 , molds  2210 , freeze hose  2215 , conveyor belt  2220 ) they want to listen to the script (bottle-building process)  2200 . 
     In several embodiments, if a listener selects to stand in front of source on the north side, the playback of the binaural audio recording will be from that perspective, giving the listener the ability to more closely hear source  2205  and  2210  sounds, while source  2215  and  2220  sounds will be heard far away. If the listener selects to stand in front of the same source  2205 , but on the south side, different sounds in different positions will be heard according to perspective. In several embodiments of the present invention, perspective will enable listener to understand normal sounds vs. abnormal sounds, and a training manual associated to abnormal sounds will allow the maintenance worker to detect and solve malfunctioning machinery. 
       FIG. 11  illustrates another embodiment of the present invention as used in conjunction with a sporting event  2300 . As shown, a binaural audio recording of a racing pit area, where the script is the behind-the-scenes of team Jimmy pit area at the 2016 West Grand Prix, and the sources for playing back the script are Sebastian Victor (driver  1 )  2305 , Team Jimmy (pit crew)  2310  and the Fan Seats  2315 . The listeners, through their personal computing device (smartphone screen), are able to select from which source&#39;s perspective (Sebastian, Pit Crew, or Fan Seats). As shown, if listener selects source  2305 , the playback of the binaural audio recording will be from one of the driver&#39;s perspectives, which means that the listener will “become” the driver in the script, and will be able to listen to what happens inside the cockpit of the Formula 1 car, along with the radio communication the driver is receiving, and the sounds associated with the pit stop. Sounds from source  2310  (pit crew) will be felt all around as the tires are changed and the car is refueled, while sounds from source  2315  will be heard to far-left from people cheering. 
       FIG. 12  illustrates another embodiment of the present invention as an audio recording is edited, optimized, mixed and mastered with the goal to generate spatial perspective  2400 . As shown audio recordings for 3D content  2405  are edited, optimized, mixed and mastered using combinations of software A  2410 , software B  2415 , and software C  2420 . The generated result is preferably master audio mix  2425  which is completely binaural, 3D and a spatial audio mix. 
       FIG. 13  illustrates several embodiments of the present invention as the master audio mix  2500  can be present in headphones, or ear buds, with pre-loaded binaural content  2510  which can then use a direct, wireless, or Bluetooth connectivity to an online store to purchase and upload more content  2530 . In alternative embodiments, digital download or streaming of content  2540  is possible from a website  2545  or from a mobile application  2550 . 
       FIG. 14  illustrates one embodiment of the steps to create binaural content and materials. As shown the binaural content and material creation  3000  is created in the following manner in one embodiment of the present invention: 
     In several embodiments, the first step is focused on content design based on human ears&#39; spatial perspective to achieve a key objective and/or benefit  3100 . One objective of the script to create a map of how an individual will experience different sound sources from different perspectives. In the script or sound map, the audio experience is outlined, scripted and/or designed for it to make sense from a spatial perspective purely through the ears. So, sounds coming from the: left, right, front, back, top, bottom, and so forth, have to make sense to the human brain to convey an objective. 
     For example, if the objective of the audio experience is to help a blind person understand distance and location of him/herself vs. surroundings, the audio source is recorded with that spatial perspective (distance) and location vs. the human being. If the objective is to experience a concern from the violins&#39; section vs. the trumpets section, the music is recording from that perspective and location, however, if the listener wants to switch from violins to the conductor, this enables the listener to do so. The audio experience can also feature movement from a story character. So, in Peter Pan, Captain Hook can move from left to right during a sword fight and the listener can experience it from Peter Pan&#39;s perspective. The listener can also switch to experience the story from Tinker Bell&#39;s perspective, and experience the same story by flying above what&#39;s happening, or by becoming part of the plot and getting trapped by Captain Hook. The same concept applies to therapy. Sounds, the intensity of sounds or messages and/or repetition from left vs. right audio consumption, will have different health implications and effects. 
     In several embodiments, in the next step  3150 , audio engineers use the content/script design to identify what type of recordings are needed. This will include but is not limited to: 3D audio recording, mono audio recordings, binaural beats, Foley and regular, and/or prerecorded sound effects. All the audio elements need to be recorded and then edited to achieve the audio experience objective. 
     In several embodiments, the final step  3200  commences, once the final edit is complete, the final mix  3200  refines the sound quality and makes emphasis where needed. This might include increasing or lowering the volume at key points within the recording; among many other final enhancements; depending on the objective. The final output is an audio experience that tricks the human brain into thinking it is experiencing something as if in the middle of the audio stimuli; when the person is physically absent. 
     In embodiments, instead of using surround sound techniques, which use multiple speakers placed in different locations, binaural audio recordings can establish direction and distance between the listener and different audio elements. For example, the listener can determine the location of a bird chirping from a tree in front of him or a cricket chirping from the grass behind him. 
     In some embodiments, once the binaural audio recording starts the playback of play, individuals use their imagination to be transported into an era or place wherein even though the listener is not physically at the play venue, the person feels they can be part of the audience or part of the cast of the play. 
     Some embodiments can create a spatial reality all around the listener. Also, music can be a vital component of the binaural audio recording. In some embodiments, when the script is a music score, a listener can select any one seat in a theater to hear the music from that acoustic location. In some embodiments, when the script is music, the listener can be the third seat trumpet player and simultaneously hear the entire score of the orchestral piece from the seat of the third trumpet player, teaching the third trumpet player how to listen and react to other instruments/players of the orchestra. 
     While these embodiments have been described with emphasis on the embodiments, it should be understood that within the scope of the appended claims, the embodiments might be practiced other than as specifically described herein.
