Creates fancy vinyl-like PNGs from music files

• Can "encode" 8-bit mono WAV files to PNG files
• Can "decode" those PNG files to re-create the original WAV

There are no releases, you'll have to build MusicImage yourself. It's as easy as dub build in the project folder though.

I recommend using ldc, as the resulting binary will run much faster than the dmd version.

dub build --compiler ldc2 -b release --parallel

• -i/--infile: The input file. Can be either a .png or a .wav file. (Required)
• -o/--outfile: The output file. Can be either a .png or a .wav file, but mustn't have the same extension as -i. (Required)
• -r/--rate: Sample rate override. Only used when decoding PNGs to WAVs. (Optional. Default: 8000)
• -d/--diameter: The diameter of the hole in the middle of the spiral. Can be used to insert downscaled album art. (Optional. Default: 80)
• -g/--gap: Gap size multiplier. Because of Reasons™, the smaller this value is, the slower MusicImage will run. (Optional. Default: 0.3)

This image decodes to this WAV file. (Standard settings: -r 8000 -d 80 -g 0.3)

(The black background and the album cover were added after the fact in Photoshop. MusicImage outputs PNGs with a transparent background.)

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

MusicImage only supports WAV files with:

• one channel
• 8 bits per sample

If you try to open anything else, MusicImage will crash. All the relevant checks are in simplewave/wavereader.d if you want to change them.
