Trim an MP3 or MP4 (and other audio/video) to a chosen start/end and export in your desired format.

Strip the lead vocal out of a song for a karaoke track, or roughly isolate the vocals.

Mix several audio/video tracks into one — per-track volume, timing, fades, pitch and ducking.

Upload a PDF, Word or text file — or paste a link to one — and listen to it read aloud. Choose a voice, set the speed, then play it or download the audio.
