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.

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: mp4 to mp3 / video to mp3. The browser capability is explicit, so a limited decoder never looks like a completed upload.
