Evaluation of models performing multi-instrument timbre transfer specifically on the CocoChorales self-reconstruction setup, utilizing objective metrics like FAD, JD, and MFCC-cos.

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 | Multi-instrument timbre transfer |
| Dataset (including any stated split) | CocoChorales self-reconstruction |
| Metric | FAD |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 6 of 6 |
| 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

- [FAD](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=FAD>): Lower is better; unit: SCALAR.

- [JD](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=JD>): Lower is better; unit: SCALAR.

- [MFCC-cos](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=MFCC-cos>): Lower is better; unit: SCALAR.

- [Confidence](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=Confidence>): Higher is better; unit: PERCENT.

- [FADm](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=FADm>): Lower is better; unit: SCALAR.

- [CCS](<https://www.sota2.com/research/sota/multi-instrument-timbre-transfer-on-cocochorales-self-reconstruction.md?metric=CCS>): Higher is better; unit: PERCENT.
