Abstract
An MPEG audio decoder has an irregular-pattern processing circuit for detecting irregular patterns in the bit stream input to the decoder, and altering these irregular patterns, or altering data or signals derived from these irregular patterns, so that the irregular patterns do not cause annoying defects in the audio signal output from the decoder. The alteration may take the form of replacement by a minimum value, or interpolation of a preceding value.
