1. for a method for audio quantization, it comprises:

  • Whether the error that the nonanticipating of definite parameter that represents audio signal fragment quantizes to cause is at predetermined thresholdUnder value;

    Determining that the described nonanticipating of described parameter quantizes the described error that causes under predetermined thresholdIn situation, provide the parameter conduct that represents audio signal fragment quantizing with described nonanticipatingA part for encoded audio signal;

    Otherwise, provide the parameter that represents audio signal fragment quantizing with predictive quantization as compilingA part for code audio signal.
