audiowaveform is a C++ command-line application that generates waveform data from either MP3, WAV, FLAC, Ogg Vorbis, or Opus format audio files. Waveform data can be used to produce a visual rendering of the audio, similar in appearance to audio editing applications. The code for the application binary can be found here. Compiled for 386, amd64, arm/v6, arm/v7, arm64, ppc64le, s390x.
Waveform data files are saved in either binary format (.dat) or JSON (.json). Given an input waveform data file, audiowaveform can also render the audio waveform as a PNG image at a given time offset and zoom level.
This is modified from audiowaveform-docker to compile audiowaveform as a completely statically linked executable that can be run anywhere without docker or any other dependencies.
git submodule init
git submodule update
docker build -t audiowaveform-build .
docker run --rm -v "`pwd`/audiowaveform:/audiowaveform" audiowaveform-build
The executable should appear at audiowaveform/build/audiowaveform.
Copy it from there to where you need it.
