Abstract:
1. A sound and light machine (SLM) that produces sound and light pulses at brain wave frequencies that is programmed to induce a particular state of consciousness in a user, while simultaneously providing music to the user, comprising: a left and a right light emitting diode (LED), the LEDs configured to be placed in front of the user's left and right eyes, respectively, and programmed to pulse light at a frequency that helps induce the particular state of consciousness in the user; a left and a right headphone speaker, the speakers configured to play different tones into right and left ears to produce binaural beats that match the LED pulse frequencies; a microcontroller that runs firmware to control the LEDs and headphone speakers so as to produce a plurality of dominant brainwave frequencies; and a plurality of binaural voices corresponding to each of said dominant brainwave frequencies, each of said binaural voices comprising a base tone, a beat tone and an associated LED, said binaural voices configured to produce a melody of said music without interfering with the sound and light pulses at the brainwave frequencies, wherein the base tone is set to a frequency producing said melody and said beat tone is set to the frequency producing said melody plus a frequency of said brain wave frequencies of the sound and light pulses, wherein said melody comprises a plurality of notes, and is stored in a song file that comprises a list of variable-length records describing each note's pitch and duration, and wherein the firmware comprises information in a Tone Object comprising a state variable index holding one of the plurality of note's current position within a waveform array and a state variable step, which is an amount by which to increment the state variable index at each iteration, wherein the index is set to 0 at startup and the step is calculated from an initial note.
