RadioSonify models and example data

This repository has mixed licensing. Do not treat every file as MIT. The MusicNet code and checkpoints are CC BY-NC 4.0 and are restricted to non-commercial use. See the inventory below and the per-component license files before use or redistribution.

Model and data asset provenance

RadioSonify downloads optional resources from TorchLight/radiosonify. The client pins an immutable commit in radiosonify.hub.REVISION; a moving branch is never used at runtime.

Asset path	Origin and modifications	License
data/Burst.npy, data/RawBurst.npy, data/ParkesBurst.npy, data/Profile.npy, data/Burst-wirfi.wav	Example artifacts shipped in the original MSP repository under its top-level license. They are provided only as small API demonstrations, not as a scientific reference dataset.	MIT
models/hifigan/config.json, models/hifigan/generator.pth	HiFi-GAN Universal V1 architecture and base checkpoint from jik876/hifi-gan, then fine-tuned by the MSP authors for 500k steps on a collection of 500 symphonic recordings. The historical repository did not retain a machine-readable corpus manifest, so users requiring training-data-level provenance should not treat this checkpoint as fully auditable.	MIT for the upstream implementation and the MSP checkpoint, to the extent of the rights held by their respective authors
models/musicnet/args.json, models/musicnet/{bestmodel,lastmodel}_{0..5}.pth	Official pretrained MusicNet archive published by Facebook Research for A Universal Music Translation Network. args.json is a safe JSON conversion of the original serialized argument object.	CC BY-NC 4.0; non-commercial use only

On 2026-08-01, all twelve hosted MusicNet checkpoint files were verified as follows: their byte size and ZIP CRC match Facebook Research's official pretrained_musicnet.zip; their SHA-256 values match the files retained in the MSP Git history and the pinned Hugging Face objects.

Instrument responses

RadioSonify 0.2.0 no longer downloads the historical piano.wav and vio.wav files because their external provenance could not be reconstructed. The piano and violin responses are now generated deterministically from analytic waveforms by radiosonify.hub, then cached locally as PCM16 WAV files. No third-party sound recording is used.

Citation

When publishing results, record the RadioSonify version, the pinned Hub revision, the selected method/checkpoint, all effective parameters, the input shape, and the input data's own provenance. The result metadata records most runtime parameters but is not a substitute for preserving the original input and its checksum.
