1. In an audio encoder, a computer-implemented method of audio encoding according to a control strategy, the method comprising:

  • encoding a sequence of audio data using a trellis to produce an output bitstream of the audio data at constant or relatively constant bitrate, wherein the trellis include plural transitions, and wherein each of the plural transitions corresponds to an encoding of a chunk of plural samples of the audio data at a quality level; and

    outputting the bitstream.
