Abstract:
An apparatus for playback of captured ambient sounds. The apparatus comprises a controller comprising a first input coupled to a respective first microphone for receiving an audio signal generated by the microphone, the audio signal representative of captured ambient sounds; a second input for receiving a playback instruction to instigate playback of ambient sounds; and an output coupled to a speaker. The apparatus further comprises data memory comprising a data structure for continuously buffering a most recent portion of the audio signal as an audio snippet. In response to detection of the playback instruction at the second input, the controller is configured to determine an output audio signal based on the audio snippet and provide the audio output signal to the output for substantially immediate playback through the speaker.

Claim (Index 52):
A method of playback of captured ambient sounds, the method comprising:\n receiving, at a first input of a controller, an audio signal generated by a microphone, the audio signal representative of captured ambient sounds; continuously buffering, by a data structure of data memory associated with the controller, a most recent portion of the audio signal as an audio snippet; receiving, at a second input of the controller, an instruction to instigate playback of ambient sounds; selectively causing a media audio signal received at a third input from an electronic device to be provided to an output coupled to a speaker to allow media from the electronic device to be played through the speaker; responsive to detecting the playback instruction at the second input:\n determining an output audio signal based on the audio snippet; \n responsive to determining that media from the electronic device is being played through the speaker, stopping providing the media source to the output; and \n providing the output audio signal to the output for substantially immediate playback through the speaker; \n wherein the method further comprises:\n scanning the received audio signal; \n identifying segments of the received audio signal as speech and/or non-speech segments; and \n determining the audio snippet based on the scanning and identifying such that the segments of speech and non-speech are associated with different playback rates.
