Commercial proof of concept
Sound Quality POC
A commercial proof of concept for comparing sounds using psychoacoustic metrics.
Commercial proof of concept00 — Context
The problem
Engineers needed to compare sounds using loudness, sharpness, roughness, and tonality without losing the signal context.
01 — Role
My contribution
- 01
Helped turn specialist psychoacoustic analysis into a guided metric-comparison workflow.
- 02
Connected metric results to the compared signals.
- 03
Made differences between sounds easier to inspect without losing the underlying signal context.
02 — Engineering
Technical approach
- 01
Group metrics around a step-by-step comparison.
- 02
Keep the source signals visible beside metric results.
- 03
Refine terminology and ordering with specialist feedback.
03 — Quality
How I checked it
- 01
Observed whether users could identify differences between sounds.
- 02
Checked metric labels and conclusions against the available evidence.
- 03
Used feedback to simplify confusing steps.
