Low delay coding of wideband audio (20Hz-15kHz) at 64kbps
Jbira A. , Nicolas Moreau , Przemysław Dymarski
AbstractA 64 kbps coder of wideband (15 kHz) monophonic audio signals is described. Its structure is based on the transform coded excitation scheme, adopted to 7 kHz band signals. Significant modifications are proposed, that yield reduction of delay while keeping an almost transparent quality of speech and music, equivalent to that provided by the MPEG-1, layer II audio standard at the same bit rate. Algorithmic delay has been reduced to 17 ms-approximately 1/3 the delay of the MPEG coder.
