适用范围

This Recommendation describes a digital wideband coder algorithm that provides an audio bandwidth of 50 Hz to 7 kHz, operating at a bit rateof 24 kbit/s or 32 kbit/s. The digital input to the coder may be 14, 15 or 16 bit 2's complement format at a sample rate of 16 kHz (handled in the same way as in Recommendation G.722). The analogue and digital interface circuitry at the encoder input and decoder output should conform to the same specifications described in Recommendation G.722.
