Useful next steps

Convert audio to another format	Create MP3, WAV, OGG, FLAC or M4A from a recording or a video soundtrack. Check the selected excerpt and listen to the exported file.
Transcribe audio and video files	Save speech from a file as TXT, SRT or VTT. Choose the language and check words, names and timestamps against the recording.
Trim and rotate a video	Choose start and end times, rotate the picture and adjust volume. Review the result as one continuous video excerpt.

Start with a moderate setting

The filter is mainly intended for relatively steady noise. Stronger processing is not always better: quiet speech details may disappear or sound artificial. Listen to pauses and word beginnings and endings. Keep the lowest setting that produces a useful improvement for your purpose.

Assess what remains

Changing noises, other voices and music may remain. The tool does not create separate vocal and instrumental tracks. Processing takes place on the server for one file up to 25 MB and ten minutes. You can choose a time range and export MP3, WAV, OGG, FLAC or M4A.
