Query: A Full-Bandwidth Audio Codec With Low Complexity And Very Low Delay   We propose an audio codec that addresses the low-delay requirements of some
applications such as network music performance. The codec is based on the
modified discrete cosine transform (MDCT) with very short frames and uses
gain-shape quantization to preserve the spectral envelope. The short frame
sizes required for low delay typically hinder the performance of transform
codecs. However, at 96 kbit/s and with only 4 ms algorithmic delay, the
proposed codec out-performs the ULD codec operating at the same rate. The total
complexity of the codec is small, at only 17 WMOPS for real-time operation at
48 kHz.
