The SX7300P provides a high performance, low cost, low complexity solution ideal for speech
transmission over the Internet or other packet networks.
The coder offers close to toll quality
speech and, with a rate of just 7300 bps, enables speech transmission over either
V.34 or V.32bis modems. At V.34 data rates multiple speech channels or multimedia applications
such as simultaneous voice and data may be supported on a single telephone line. The small frame
size of the coder provides low end-to-end delay. A powerful frame reconstruction algorithm yields
exceptionally robust performance in the presence of channel errors.
The low delay characteristics
and good tandeming performance make it ideal for multi-party conferencing. Modest memory and
processing power requirements enable implementations of the coder in either Pentium™ environments
or on inexpensive DSPs. The SX7300P offers speech quality comparable with ITU-T G.723 and G.729
Annex A with enhanced performance in the presence of lost speech frames and at significantly
lower complexity and lower cost. Voice Activity Detection and Comfort Noise generation is optional.
