A low delay sub-band audio coder (20 Hz-15 KHz) at 64 kbit/s

Résumé

a new method for coding generic audio signals at 64 kbit/s in the bandwidth 20-15000 Hz with a low delay is presented. It combines sub-band coding, low delay CELP algorithm and cascaded filterbanks. We show how the different parameters of LD-CELP can be adapted to achieve a better quality, perceptual coding techniques are integrated into the encoder for allocating bits to each sub-band.
