Field notes
Tonera exposes the intermediate cleanup process rather than treating transcription as a one-click black box: users can adjust minimum note length and frame thresholds before exporting. The page recommends using the original MP3 instead of converting it to WAV, noting that a new container cannot restore information removed by compression. Standard processing remains in-browser, while optional stem separation uses Replicate and costs two credits.
