Abstract:
1. A method for managing bit-errors present in an audio-encoded bit stream representative of a portion of an audio signal, comprising: receiving the audio-encoded bit stream over a communication channel; decoding the encoded bit stream to produce a series of decoded digital audio samples; analyzing both the audio-encoded bit stream and the series of decoded digital audio samples to estimate at least one of a distribution, extent and location of bit errors in the audio-encoded bit stream; when bit errors are detected in the audio-encoded bit stream, selecting a first one of a plurality of means for producing a series of digital audio samples representative of the portion of the audio signal based on determining that there is at least one of a first estimated distribution, extent and location of bit errors in the audio-encoded bit stream and selecting a second one of the plurality of means for producing the series of digital audio samples representative of the portion of the audio signal based on determining that there is at least one of a second estimated distribution, extent and location of bit errors in the audio-encoded bit stream; and converting the series of digital audio samples produced by the selected means into a form suitable for playback to a user.
