ABSTRACT:
The present invention includes a system and method for audio signal conversion using frequency band division. By making use of the statistical properties of an audio signal, the system and method achieves significant coding efficiency, on the order of twice that achieved by linear PCM. Quantization is performed on multiple frequency bands of audio data which have different power density characteristics and sample rate requirements.
