This audio & video speed changer and pitch shifter lets you import MP4, MKV, WAV, and MP3 files, extract audio for waveform editing, and play or export as MP3/WAV while independently adjusting Pitch, Tempo, and Formant.

With A-B looping, playback marking, waveform editing, and vocal processing, it is ideal for music transcription, vocal practice, dance routines, language learning, and audio analysis.
