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.
See requirements.txt
for specifics
Simply running python3 main.py
will generate audio using the test image and
default settings.
The following optional arguments may be set, however:
-p
for a path to an image-o
for path to save the output file to-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)-ts
to set the time signature (defaults to 1/1, essentially "no feel")
The algorithm now uses Blackman smoothing by default. The original conversion method had a characteristic "clicky" sound due to incomplete wave forms. To achieve the original sound, pass
--nosmooth
.
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).
Adding --reveal
will override the key, tempo, and minutes/seconds with data
derived from the image itself, "revealing" the music within the image
"Reveal" mode plus overrides
You can specify arguments as overrides in conjunction with "Reveal" mode. For example, if you want to make sure that the key is D-Major, but you want the other parameters to be derived from the image, run
python3 main.py -key D-Major --reveal
Adding --method2
will utilize an experimental new conversion method that
limits the left and right channels to specific frequency ranges, simulating "
left-hand" and "right-hand" keyboard parts. Please note that this method does
not currently support "Split" mode.
Example 1:
python3 main.py -p image.png -key D-minor -t 80 -min 11 -sec 38
Example 2:
python3 main.py -p image.png -key D-minor -t 80 -min 11 -sec 38 --split
Example 3:
python3 main.py -p image.png --reveal
Example 4:
python3 main.py -p image.png -key G-Major -t 96 -min 4 -sec 20 -ts 3/4 --split
