LAME与一般MP3编码器与众不同,它支持几乎所有能够采用到MP3编码中的技术,LAME支持CBR(固定码率)和VBR(动态码率,还有一个效果不是很出众的ABR),LAME是MP3史上具有里程碑意义的软件,LAME是一个Command line程序,象Dos程序一样需要手工输入,而且参数及其复杂,但可很方便的供其他程序调用,LAME同时也提供了一个DLL版本,...

MP3解码算法分析(1)——MP3文件解剖 1. MP3 编码器(Encoder)常见问题 - 什么是 MP3 编码器?一个 MP3 编码器是一个使用 MP3 编解码算法(压缩/解压)创建 mp3 文件的软件。 大部分编码器只转化一 个 WAV 文件到 MP3 文件,尽管很多可以转化其他格式,如 WMA, Real Audio, Ogg, 等等。只有很小几个独立的...
This is only an official reference data table, in the course of practical use, the bit rate is 128 cant show the CD sound quality, although mp3 compression using software algorithm in the process of different will have some differ 下载文档,永久保存 ...
Double MP3 compressionHigh bitrateMP3 is the most widely used audio format nowadays in our daily life, while MP3 audio often be forged by an audio forger for their own benefits in some significant events, which will cause double MP3 compression. In this paper, it is the first time to ...
It uses the lossy compression algorithm to contain audio data. The lossy compression helps to reduce the data significantly without losing audio quality. MP3s are created using different bit rates maintaining the original quality. Convert from MP3 MP3 to AAC MP3 to AIFF MP3 to FLAC MP3 ...
