waveman2 is the Golang successor the first waveman, built to convert audio files
(later, only mp3), into cool-looking, more abstract audio waveforms, by reducing
the samples to a smaller-sized slice and rendering out SVGs.
See https://github.com/zoomoid/wave-man for the original project written in Python. Be warned, decoding is slow, even though the audio file is resampled to 16 times lower sampling rate before processing, and the project depends on several utilities to decode mp3 files and convert them to PCM before tranformation.
waveman2 is designed to be both extensible with other painters than the default
ones, and also to be imported into any other Golang project as a dependency.
This way, you can easily realize the original idea of waveman to be combined
with a web server that processes audio files sent to the server with a set of
defaults and/or user-defined properties, without having to implement web server
functionality in the waveman codebase itself.
See ./docs for the command manual.
You can build the project from source by cloning the repository and then running
# Downloads all the go dependencies needed to build
$ go get -d -v ./...
# Builds a binary named "waveman" in the local directory
$ go build -o waveman
# Run waveman locally
$ ./waveman
