On frequency quantization in sinusoidal audio coding
收藏 引用
IEEE SIGNAL PROCESSING LETTERS 2005年 第3期12卷 210-213页
作者: Vafin, R Prakash, D Kleijn, WB KTH Royal Inst Technol Dept Signal Sensors & Syst S-10044 Stockholm Sweden
In this work, we develop a new method for jointly optimal quantization of sinusoidal frequencies, amplitudes, and phases and apply the method to sinusoidal audio coding. This is an extension of an earlier work on quan... 详细信息

Perceptual filter design for audio coding using psychoacoustic modelling
收藏 引用
ELECTRONICS LETTERS 1998年 第8期34卷 747-748页
作者: Lam, YH Stewart, RW Univ Strathclyde Dept Elect & Elect Engn Signal Proc Div Glasgow G1 1XW Lanark Scotland
A generalised perceptual filter which aims to reduce the audible quantisation noise in low bit rate audio coding has been developed. The filter derivation is based on a psychoacoustic excitation pattern model. Experim... 详细信息
