What to expect
- Supported inputs
- MP3, M4A, WAV, OGG, FLAC, and other recordings this browser can read, or a video whose sound you want.
- What happens
- Pauses longer than your setting are shortened rather than removed outright. The parts kept are copied from the original without re-encoding, so the sound isn't changed.
- Limits
- Music or steady noise under the speech hides the pauses. “Um”s and “uh”s can be cut in English only.
