The problem
Comparing two recordings is not a byte comparison. Meaningful differences live in the waveform and in what was actually said — and neither a binary diff nor a plain text diff captures both.
The approach
- 01
Built waveform-level comparison across WAV files.
- 02
Paired it with transcript diffing so text and audio differences are reported together.
- 03
Produced detailed segment analysis, so the output localises where recordings diverge rather than just reporting that they do.
- 04
Packaged and published to npm as a typed TypeScript library.
The outcome
A published, installable npm package that gives audio and transcript diffing with per-segment detail.
Built with
