| # Model and data asset provenance |
|
|
| RadioSonify downloads optional resources from |
| [`TorchLight/radiosonify`](https://huggingface.co/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`](https://github.com/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](https://github.com/facebookresearch/music-translation). `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. |
