1. A scalable audio processing method for a processing device, comprising:

  • transform coding frames of input audio from a time domain into transform coefficients in a frequency domain;

    allocating, for each frame, total available bits of an encoding bit rate into first and second bit allocations, the first bit allocation allocated for a first set of the transform coefficients of the frame, the second bit allocation allocated for a second set of the transform coefficients of the frame;

    packetizing, for each frame, the first and second sets of the transform coefficients with the corresponding first and second bit allocations into a packet; and

    transmitting the packets with the processing device.
