编译安装SOX

1下载

http://sox.sourceforge.net/

2编译

autoreconf -i    之后生成configure

./configure       生成makefile
make

make install     生成可执行程序和SOX动态/静态库

3安装附加库

参考：https://audiodigitale.eu/?p=25

brew install opencore-amr libao flac two-lame libtool mad libid3tag libmagic libvorbis libpng libsndfile wavpack lame

 4 安装过程用到的一些编译工具：

auto-archive,glibtool, autoconfig 等，根据编译错误，查询需要安装的编译工具

5 安装过程中出现configure编译不过：

   找到编译不过的选项，可以先删除；

The current release handles the following audio file formats:

The audio effects/tools included in this release are as follows:

• Tone/filter effects
  • allpass: RBJ all-pass biquad IIR filter
  • bandpass: RBJ band-pass biquad IIR filter
  • bandreject: RBJ band-reject biquad IIR filter
  • band: SPKit resonator band-pass IIR filter
  • bass: Tone control: RBJ shelving biquad IIR filter
  • equalizer: RBJ peaking equalisation biquad IIR filter
  • firfit+: FFT convolution FIR filter using given freq. response (W.I.P.)
  • highpass: High-pass filter: Single pole or RBJ biquad IIR
  • hilbert: Hilbert transform filter (90 degrees phase shift)
  • lowpass: Low-pass filter: single pole or RBJ biquad IIR
  • sinc: Sinc-windowed low/high-pass/band-pass/reject FIR
  • treble: Tone control: RBJ shelving biquad IIR filter
   
• Production effects
  • chorus: Make a single instrument sound like many
  • delay: Delay one or more channels
  • echo: Add an echo
  • echos: Add a sequence of echos
  • flanger: Stereo flanger
  • overdrive: Non-linear distortion
  • phaser: Phase shifter
  • repeat: Loop the audio a number of times
  • reverb: Add reverberation
  • reverse: Reverse the audio (to search for Satanic messages ;-)
  • tremolo: Sinusoidal volume modulation
   
• Volume/level effects
  • compand: Signal level compression/expansion/limiting
  • contrast: Phase contrast volume enhancement
  • dcshift: Apply or remove DC offset
  • fade: Apply a fade-in and/or fade-out to the audio
  • gain: Apply gain or attenuation; normalise/equalise/balance/headroom
  • loudness: Gain control with ISO 226 loudness compensation
  • mcompand: Multi-band compression/expansion/limiting
  • norm: Normalise to 0dB (or other)
  • vol: Adjust audio volume
   
• Editing effects
  • pad: Pad (usually) the ends of the audio with silence
  • silence: Remove portions of silence from the audio
  • splice: Perform the equivalent of a cross-faded tape splice
  • trim: Cuts portions out of the audio
  • vad: Voice activity detector
   
• Mixing effects
  • channels: Auto mix or duplicate to change number of channels
  • divide+: Divide sample values by those in the 1st channel (W.I.P.)
  • remix: Produce arbitrarily mixed output channels
  • swap: Swap stereo channels
   
• Pitch/tempo effects
  • bend: Bend pitch at given times without changing tempo
  • pitch: Adjust pitch (= key) without changing tempo
  • speed: Adjust pitch & tempo together
  • stretch: Adjust tempo without changing pitch (simple alg.)
  • tempo: Adjust tempo without changing pitch (WSOLA alg.)
   
• Mastering effects
  • dither: Add dither noise to increase quantisation SNR
  • rate: Change audio sampling rate
   
• Specialised filters/mixers
  • deemph: ISO 908 CD de-emphasis (shelving) IIR filter
  • earwax: Process CD audio to best effect for headphone use
  • noisered: Filter out noise from the audio
  • oops: Out Of Phase Stereo (or `Karaoke') effect
  • riaa: RIAA vinyl playback equalisation
   
• Analysis `effects'
  • noiseprof: Produce a DFT profile of the audio (use with noisered)
  • spectrogram: graph signal level vs. frequency & time (needs `libpng')
  • stat: Enumerate audio peak & RMS levels, approx. freq., etc.
  • stats: Multichannel aware `stat'
   
• Miscellaneous effects
  • ladspa: Apply LADSPA plug-in effects e.g. CMT (Computer Music Toolkit)
  • synth: Synthesise/modulate audio tones or noise signals
  • newfile: Create a new output file when an effects chain ends.
  • restart: Restart 1st effects chain when multiple chains exist.
   
• Low-level signal processing effects
  • biquad: 2nd-order IIR filter using externally provided coefficients
  • downsample: Reduce sample rate by discarding samples
  • fir: FFT convolution FIR filter using externally provided coefficients
  • upsample: Increase sample rate by zero stuffing
    + Experimental or incomplete effect; may change in future.

Multiple audio files can be combined (and then further processed with effects) using any one of the following combiner methods:

• concatenate
• mix
• merge: E.g. two mono files to one stereo file
• sequence: For playing multiple audio files/streams
