If you want to know the relationship between the MP3 frequency, bit rate, bit rate, and sound quality, the higher the frequency, the higher the bit rate, the better the sound quality. It seems that most of the MP3 frequencies are 44100hz. The bit rate is 128,192.
The frequency mentioned here is the sampling rate, which is usually 44100khz, because it is the standard of music CD.Every song is captured from Cd, converted into wav files, and then converted into MP3 using

This guide is based on a minimal centos installation and Will installffmpeg with several external encoding libraries.
Note:The # indicates that the commandshoshould be executed as superuser or root.
Preparation
Remove any existing packages:
# Yum erase FFMPEG x264x264-devel
Get the dependencies:
# Yum install GCC git makenasm pkgconfig wget
Make a source directory:
Mkdir ~ /FFMPEG-Source
Installation
Yasm
Yasm is an attacker used by x264 and FFMPEG.
Cd ~ /FFMPEG-Source

monkey ' s audio has a tool MAKEAPL (Setup has set up shortcuts for it in the Start menu),
Can convert cue file into several corresponding APL files each APL corresponds to a track, and Winamp support APL, so everything OK
C. Install a Winamp plug-in called Mp3cue that enables Winamp to support cue files
Note: According to my own experiments, to normal use the plug-in should be added to the Winamp playlist image file, unlike Foobar is added cue file, as long as the directory has the same name c
make install. This makefile is correct, so it is easier. 4. In the directory specified by -- prefix of faad and faac, copy the. H files in the include directory.
To/usr/include, copy all the files starting with LIB under their lib directory to the/usr/lib directory. If faad and faac are not compiled before
Do not specify -- prefix. This copy step is not required. Note that if you only copy the libfaad. A and libfaac. A static library files
FFmpeg has no dynamic library dependency on them and ca

PS: The article that was written a long time ago was rejected. I found it when I sorted out the hard disk today. paste it.
Nowadays, there are a lot of software that directly converts MP3 files from CD files, but the compression quality of MP3 files is really unbearable for music enthusiasts, however, the inconvenience caused many people to fear. After many trials, I have finally found a balance between the two. I am not dedicated here. Now I have written this article. If there is anything w
