are notoriously difficult signals for parametric coders such as si-nusoidal models. During a transient, transform coding is used to represent the signal. At all other times, sinusoidal and noise mod-eling represent the signal. Because of phase-matching algorithms, the parametric and transform systems can switch seamlessly.

Transform or subband audio coders can deliver high quality reconstruction at rates around two bits per sample. Most quantization strategies take into account masking properties of the human ear to amke the quantization noise less noticeable.
