This Space serves a single-page scrollable survey for subjective evaluation of noise reduction quality.

Instructions:
- Each question has a Noise Reference (if available), plus two anonymized audios: Audio A (1‑prefixed) and Audio B (2‑prefixed).
- Task: select which audio contains less of the original noise.
- Click "Submit All" to export a CSV with your results.

Scoring note: any audio filename containing `t0.99` is treated as the wrong option; the other one is counted as correct.

Build/runtime:
- `requirements.txt` pins `gradio>=4.44.1` to avoid schema issues.
