Abstract

The HILN (Harmonic and Individual Lines plus Noise) MPEG-4 parametric audio coding tool allows efficient representation of general audio signals at very low bit rates. Therefore possible applications include transmission over IP or wireless channels which are both characterised by specific transmission error models. On the other hand, since parametric audio coding is a relatively new technique compared to transform coding and CELP speech coding, there have been only very limited investigations on HILN's behaviour in error prone environments. In this paper we present an analysis of error sensitivities and approaches to error protection and concealment.
