Local audio utility

Trim audio. Keep it local.

Trim controls are not enabled yet. The current workbench converts a supported local file to WAV without range selection. Your file never enters a server queue.

Output format

This route is mapped from the survey, but the browser export currently supports WAV only. MP3 and M4A encoders are not enabled yet.

Choose a file to unlock the conversion path.

Browser-native processing keeps the original on your device. Output quality depends on the decoder available in your browser.

Route intent from the supplied CSV: audio trimmer / cut mp3 / trim audio. The browser capability is explicit, so a limited decoder never looks like a completed upload.
