Evaluation of Direction of Arrival (DOA) Estimation performance on the full SOFA dataset, reporting angular error metrics and percentage accuracy at various error tolerances.

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 | Direction of Arrival Estimation |
| Dataset (including any stated split) | SOFA (full) |
| Metric | Accuracy (\< 5°) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [Accuracy (\< 5°)](<https://www.sota2.com/research/sota/direction-of-arrival-estimation-on-sofa-full.md?metric=Accuracy%20(%3C%205%C2%B0)>): Higher is better; unit: PERCENT.

- [Accuracy (\< 10°)](<https://www.sota2.com/research/sota/direction-of-arrival-estimation-on-sofa-full.md?metric=Accuracy%20(%3C%2010%C2%B0)>): Higher is better; unit: PERCENT.

- [Accuracy (\< 15°)](<https://www.sota2.com/research/sota/direction-of-arrival-estimation-on-sofa-full.md?metric=Accuracy%20(%3C%2015%C2%B0)>): Higher is better; unit: PERCENT.

- [Angular Error (Avg)](<https://www.sota2.com/research/sota/direction-of-arrival-estimation-on-sofa-full.md?metric=Angular%20Error%20(Avg)>): Lower is better; unit: SCALAR.

- [Improvement vs Baseline (%)](<https://www.sota2.com/research/sota/direction-of-arrival-estimation-on-sofa-full.md?metric=Improvement%20vs%20Baseline%20(%25)>): Higher is better; unit: PERCENT.
