Abstract:
1. An apparatus, comprising: a jitter buffer to store packets of encoded audio information; a decoder to connect to said jitter buffer, said decoder to decode said encoded audio information into frames of audio information; a pitch management module to connect to said decoder, said pitch management module having a pitch control module and a delay buffer, said delay buffer to store a next frame of audio information to be reproduced, said pitch control module to add audio information to said delay buffer to synchronize a pitch for a next frame and a reproduced frame based on a number of said packets stored in said jitter buffer, said pitch control module to determine whether said audio information in said delay buffer is greater than a frame size, said pitch control module to send a first signal to said jitter buffer to suspend removal of packets of audio information from said jitter buffer if said audio information in said delay buffer is greater than said frame size, and said delay buffer to output frames of audio information until said audio information in said delay buffer is less than one frame size.
