How to install SoX on CentOS 6
To install SoX on CentOS 6
SoX (Sound eXchange) is a cross-platform sound file format converter. SoX can convert between many different digitized sound formats and perform simple sound manipulation functions, including sound effects. It can combine multiple input sources and synthesise audio and act as general purpose audio player or a multi-track audio recorder. This tutorial covers the installation procedure of SoX on CentOS 6.
Installation procedure
To start with the installation procedure of SoX, download the required repository using wget command followed by the download link.
[root@linuxhelp ~]# wget http://repository.it4i.cz/mirrors/repoforge/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

Next install the required dependencies for the SoX to run in the environment. Execute the yum install command followed by the dependencies.
[root@linuxhelp ~]# yum install gcc-c++ libmad libmad-devel libid3tag libid3tag-devel lame lame-devel flac-devel libvorbis-devel

-rwxrw-rw- 1 root root 1322298 Oct 31 16:42 Kurzweil-K2000-Dual-Bass-C1.wav
Convert the sound file to .wav format using SoX applicaton and now list the files in the intended directory. There will be the original sound file along with the converted one.
[root@linuxhelp Desktop]# sox Kurzweil-K2000-Dual-Bass-C1.wav Kurzweil-K2000-Dual-Bass-C1.mp3
[root@linuxhelp Desktop]# ll
total 1412
-rw-r--r-- 1 root root 120372 Oct 31 16:47 Kurzweil-K2000-Dual-Bass-C1.mp3
-rwxrw-rw- 1 root root 1322298 Oct 31 16:42 Kurzweil-K2000-Dual-Bass-C1.wav
Now view the properties of the converted file format and you can see the file format has been changed from .wav to .mp3 file format.
The original file format as .wav file along with file location is viewed in the properties window.
The file is running successfully in the system.
Thus we conclude the installation procedure of SoX on CentOS 6.

Q
What are the best 'rate' settings to resample a file and retain the highest quality?
A
Resampling is a series of compromises so there's no one true answer for all situations, but the following rules of thumb should cover most people's needs for 99% of the time:
Phase setting: if resampling to < 40k, use intermediate phase (-I), otherwise use linear phase (-L, or don't specify; linear phase is the default).
Quality setting: if resampling (or changing speed, as it amounts to the same thing) at/to > 16-bit depth (i.e. most commonly 24-bit), use VHQ (-v), otherwise, use HQ (-h, or don't specify).
Bandwidth setting: don't change from the default setting (95%).
If you're mastering to 16-bit, you also need to add 'dither' (and in most cases noise-shaping) after the rate.
Time for some examples:
sox any-file -b 16 outfile rate 44100 dither -s
(mastering for CDDA).
sox 24-bit-file outfile rate -v 88200
(outfile bit depth unchanged at 24-bit).
sox any-file -b 16 outfile rate -I 22050 dither -s
N.B. Both resampling and dithering require some headroom. If SoX reports that any clipping has occurred during processing then the conversion should be redone with some attenuation, e.g.
sox any-file -b 16 outfile gain -1 rate 44100 dither -s
Phase setting: if resampling to < 40k, use intermediate phase (-I), otherwise use linear phase (-L, or don't specify; linear phase is the default).
Quality setting: if resampling (or changing speed, as it amounts to the same thing) at/to > 16-bit depth (i.e. most commonly 24-bit), use VHQ (-v), otherwise, use HQ (-h, or don't specify).

sox any-file -b 16 outfile gain -1 rate 44100 dither -s
Q
Why doesn't this SoX command line I found on the internet work?
A
A number of potentially confusing options have been replaced with what we hope are less confusing ones; e.g. -b & -w in SoX versions prior to 14.1.0 are now -b (or --bits) 8, and -b 16, and -e is now -n.
