mp3readandmp3write
说明: mp3read和mp3write是直接写在wavread更换和wavwrite访问MPEG音频MP3文件。其特点包括: -旨在重复wavread完整语法和wavwrite -还支持上的动态下采样和渠道mpg123的合并-文件优化的很长的MP3 -只需要解码的部分-使用popen函数进行编码,以避免大量临时文件(可用时-看到我popenw墨西哥) -试图消除写保护回路的时间序列文件/通过阅读“热身”样本-包括辅助二进制软件包在Linux,Windows,Mac的PPC的,苹果,英特尔,和Mac英特尔- 64位(These versions of mp3read and mp3write are direct drop-in replacements for wavread and wavwrite to access MPEG audio mp3 files. Features include:
- aims to duplicate complete syntax of wavread and wavwrite
- also supports on-the-fly downsampling and channel merging of mpg123
- optimized for very long mp3 files- only decodes the needed portion
- uses popen for encoding to avoid a large temporary file (when available- see my popenw mex)
- attempts to preserve time alignment of files through read/write loop by removing "warm up" samples
- package includes helper binaries for Linux, Windows, Mac-PPC, Mac-Intel, and Mac-Intel-64bit
