ABSTRACT:
A method and apparatus for using and combining sub-frame processing and adaptive jitter-buffers for improved voice quality in voice-over-packet networks. Data is placed in a jitter buffer, where the data has a frame-length consisting of a plurality of samples. Some of the samples are placed in the DMA buffer, and some of the samples are placed in the back-up buffer. Samples are read out of the DMA buffer, and samples are moved from the back-up buffer to the DMA buffer.
