image2sound 0.5

A Python utility that converts images to audio.

image2sound

image2sound is a utility that accepts an image file, converts the RGB values of each pixel to a frequency, and saves the result to three separate WAV files.

NOTE: Large image files no longer automatically result in large audio files as the user can specify a target track length and sane defaults are applied when this is not specified.

Requirements

• PIL
• numpy
• wavio
• argparse
• math

To run

Simply running python3 main.py will generate audio using the test image and default settings.

Arguments

The following optional arguments may be set, however:

• -p for a path to an image
• -key for musical key (defaults to C )
• -t for tempo (defaults to 60 bpm)
• -min for the desired number of minutes (defaults to 1 so must be set to zero if shorter tracks are wanted)
• -sec for the desired number of seconds (defaults to zero)

"Split" mode

Note that the default behavior of the utility is to create a single stereo audio file. Adding --split will split the resulting audio into three separate files (red, green, blue).

"Reveal" mode

Adding --reveal will override the key, tempo, and minutes/seconds with data derived from the image itself, "revealing" the music within the image as it were,

Example 1:

python3 main.py -p image.png -key Dminor -t 80 -min 11 -sec 38

Example 2:

python3 main.py -p image.png -key Dminor -t 80 -min 11 -sec 38 --split

Example 3:

python3 main.py -p image.png --reveal
