Evaluation of Audio Super-Resolution performance on the out-of-domain split of the MUSDB18-HQ dataset, measured using LSD, LSD-HF, and ViSQOL.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Audio Super-Resolution |
| Dataset (including any stated split) | MUSDB18-HQ Out-of-domain |
| Metric | LSD |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 16 of 16 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [LSD](<https://www.sota2.com/research/sota/audio-super-resolution-on-musdb18-hq-out-of-domain.md?metric=LSD>): Lower is better; unit: SCALAR.

- [LSD-HF](<https://www.sota2.com/research/sota/audio-super-resolution-on-musdb18-hq-out-of-domain.md?metric=LSD-HF>): Lower is better; unit: SCALAR.

- [ViSQOL](<https://www.sota2.com/research/sota/audio-super-resolution-on-musdb18-hq-out-of-domain.md?metric=ViSQOL>): Higher is better; unit: SCALAR.
