METHOD AND APPARATUS FOR ENCODING AUDIO DATA

摘要

Provided are an audio data encoding method and apparatus including determining an initial scale factor value for each frequency band of the audio data according to a quantization error and a maximum permissible distortion level for each frequency band; comparing the initial scale factor value for each frequency band and a predetermined common scale factor value and determining a final scale factor value for each frequency band based on a comparison result; quantizing the audio data using the final scale factor value for each frequency band; and encoding the quantized audio data.
