The Problem

Arabic TTS is booming — but who checks the quality?

13+ models competing on the Arabic TTS Arena. Teams ship audio with silence gaps, clipping, low volume, background noise, and wrong sample rates. Everyone builds ad-hoc scripts to catch the same problems. samt runs 20 checks on any WAV file and gives you a single quality score. Offline. No API. Pure Python stdlib.

20 Checks

Five categories. Every audio problem caught.

Each check has clear thresholds and contributes to the overall quality score.
