FMRadioSR

FM Radio Super Resolution

This is a model designed to upscale recordings of FM radio. It was created using the Aero architecture with a modified version of the "Aero" project:

• Modified Project: https://github.com/pokepress/aero
• Original: https://github.com/slp-rl/aero

Usage:

1. Check out and install the modified version of the Aero project and put the checkpoint file in the working directory.
2. If needed, convert the audio recordinng to 44.1 khz stereo.
3. Call the new project with:

python predict.py experiment=aero_441-441 +filename="PATH_TO_AUDIO_FILE" +output="PATH_TO_OUTPUT_DIRECTORY" checkpoint_file="PATH_TO_CHECKPOINT_FILE"

The model should be able to:

• Reduce stereo hiss
• Reduce certain kinds of static/interference
• Reduce 19khz stereo pilot
• Reduce overly warm bass frequencies (boost them 3 or so dB if you miss them)
• Restore lost high & low frequencies (generally only up to 16khz since most training data is MP3-based)

Things to be aware of:

• The model isn't currently great at removing static from the mono (L+R) channel, as those have been dificult to reproduce using the equipment I have.
• The "predict" script will normalize the audio after running inference on the whole file, so it likely will be at a different volume than the source track.
• The model was trained from audio digitized directly off the radios used, but should work decently for recordings digitized from cassette tapes, etc.
