 We propose the Opus codec based on a linear prediction layer (LP) and an
 MDCT-based layer. The main idea behind the proposal is that
 the speech low frequencies are usually more efficiently coded using

 are more efficiently coded in the transform domain (e.g. MDCT). For low 
 sampling rates, the MDCT layer is not useful and only the LP-based layer is
 used. On the other hand, non-speech signals are not always adequately coded
