MusicImage (but written in Go this time)

Creates fancy vinyl-like PNGs from music files

Features

• Can "encode" mono/stereo 8-24 bit WAV files to PNG files
  • (with the exception of 16-bit stereo files)
• Can "decode" PNG files to re-create the original WAV
• Support for "deep color" PNG files to fit more samples into a single pixel

Download

There are no releases, you'll have to build MusicImage yourself. If your Go development environment is set up properly, this should be as easy as running:

go get
go build

Usage

To create PNGs from WAV files:

$ musicimage -i infile-11025hz.wav -o encoded.png

To recreate the WAV file from a PNG:

$ musicimage -i encoded.png -o outfile-decoded.wav

General Options

• -d/--diameter: The diameter of the cutout in the middle of the image. Can be used to insert album covers in a vinyl label-like fashion. (Optional. Default: 64)
• -s/--separation: The distance between spiral turns, in pixels. (Optional. Default: 1)
• -D/--deep: Treats PNGs as 64-bit PNGs to stuff more data into or read more data from a single pixel. (Optional. Default: 1)

PNG → WAV Options

• -r/--bitrate: Sample rate override. (Optional. Default: 11025)
• -b/--bitdepth: Bit depth override. (Optional. Allowed values: 8, 16, 24. Default: 8)
• -c/--channels: Channel number override. (Optional. Allowed values: 1, 2. Default: 1)

Example

This image decodes to this WAV file (with the standard settings: -d 64 -s 1 -r 11025 -b 8 -c 1)

(The full song is available on iTunes and on Spotify, by the way. It's great.)

Limitations

MusicImage only supports WAV files with:

• one or two channels
• 8, 16, or 24 bits per sample
  • 16-bit stereo WAV files are not supported at all
