“…In other words, all the known methods for evaluating nonlinear distortion are very sensitive to the level of additive noise and rather inaccurate. To increase the accuracy in these evaluations, various methods have been proposed, in particular methods of regularization [6], introduction of parametric feedback [7] and others.…”

A simple yet elegant analog based technique for restoring the fidelity of playback audio signals emanating from magnetic cassette tapes is presented. The technique makes use of information from the high frequency bias signal in magnetic cassette tapes to correct for errors in the playback audio signal. Performance evaluation of the developed technique shows that the technique can correct for errors due to noise, scratches on the tape surface, clipping, and non-linear distortion. The developed technique will be valuable in restoring the fidelity of playback audio signal from magnetic cassette tapes stored in archives and private homes.
