Abstract
This disclosure details the implementation of apparatuses, methods and systems for audio processing and transmission. Some implementations of the system are configured to provide a method for encoding an arbitrary number of audio source signals using only a small amount of (transmitted or stored) information, while facilitating high-quality audio playback at the decoder side. Some implementations may be configured to implement, a parametric model for retaining the essential information of each source signal (side information). After the side information is extracted, the remaining information for all source signals may be summed to create a reference signal from which noise information for the original source signals may be reconstructed. The reference signal and the side information form the new collection of information to be transmitted or stored for subsequent decoding.
