AB - In order to exploit the full dynamic range of communicationsand recording equipment, and to minimise the effects of noiseand interference, input gain to a recording device is typicallyset as high as possible. This often leads to the signal exceedingthe input limit of the equipment resulting in clipping. Com-munications devices typically rely on codecs such as GSM06.10to compress voice signals into lower bitrates. Althoughdetecting clipping in a hard-clipped speech signal is straight-forward due to the characteristic flattening of the peaks of thewaveform, this is not the case for speech that has subsequentlypassed through a codec. We describe a novel clipping detec-tion algorithm based on amplitude histogram analysis and leastsquares residuals which can estimate the clipped samples andthe original signal level in speech even after the clipped speechhas been perceptually coded.
