摘要:
A method of processing digital audio data includes receiving an input stream of audio data having a first quantization and a high oversampling rate. The input stream is requantized in a first processing block at the high oversampling rate to a second quantization. The requantized stream of audio data is processed in a second processing block at the high oversampling rate and the second quantization.
