Error Correction by Interpolation in Digital Audio

Authors: Filliat, Laurent; Rossi, Mario; Maisano, Joseph

AES Convention 92 · Paper 3281 · March 1992

Abstract

One of the well known Swiss recorder manufacturers asked how to continue correcting a digital audio signal when the corrector code is overflowed. It was successfully done by a new method: Adaptative Lagrange interpolation with local filtering. The mute is done with the same algorithm. It is implemented in a DSP on a digital audio recorder together with the corrector code for a complete real-time correction.
