Patent ID: 8489403

Claim:
A multi-channel audio encoding processor-implemented method, comprising: receiving a plurality of audio inputs from a plurality of audio channels; determining a primary channel input and a plurality of secondary channel inputs from the received plurality of audio inputs; segmenting each audio input into a plurality of audio frames; determining a plurality of sinusoidal parameters of the segmented audio frames based on all channel inputs; for the primary audio channel input, modifying the determined plurality of sinusoidal parameters via a pre-conditioning procedure at a frequency domain; for secondary audio channel frames, obtaining frequency indices of sinusoidal parameters from primary audio channel encoding; converting the modified plurality of sinusoidal parameters into a modified time domain representation; obtaining a plurality of random measurements from the modified time domain representation; generating binary representation of the segmented audio frames of all channels by quantizing the obtained plurality of random measurements; and sending the generated binary representation of the segmented audio frames of all channels to a transmission channel.
