摘      要：We present a flexible audio coding system for use in the continuous transmission of high-quality (192-kHz sampling rate, 24-bit digitization (mac)) stereo-audio data streams, either live or recorded The system provides both lossless and variable-level lossy quality, quality is selectable to suit a full range of wide- and narrow-band IP networks As input signals for transmission at the server PC, less than nine PCM sound files in different formats are simultaneously encodable, and the efficiency of simultaneous compression is very high. The system is realized by software that runs on a typical PC This gives everyone on an IP network the ability to transmit high-quality sound anywhere within the network An MPEG-4 audio codec provides the core of the lossy coding module.
