audiowaveform

audiowaveform is a C++ command-line application that generates waveform data from either MP3, WAV, or FLAC format audio files. Waveform data can be used to produce a visual rendering of the audio, similar in appearance to audio editing applications.

Run

$ docker pull vimagick/audiowaveform
$ alias awf='docker run --rm -v `pwd`:/work -w /work vimagick/audiowaveform'
$ awf -i input.mp3 -o output.png
