realies/audiowaveform repository overview

⁠Audio Waveform Image Generator Docker Container

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.

⁠Typical Usage

⁠Using Docker CLI

alias awf='docker run --rm -v `pwd`:/tmp -w /tmp realies/audiowaveform'
awf -i input.wav -o output.png
