International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R.C. Hendriks R. Heusdens J. Jensen Department of Mediamatics Delft University of Technnology Delft Netherlands
Sinusoidal coding of an audio subject to a bit-rate constraint, in general, results in a noise-like residual signal. This residual signal is of high perceptual importance; reconstruction of audio using the sinusoidal ... 详细信息
