grepgrep

grepgrep is a desktop audio practice and transcription app for musicians.

It is designed for learning songs by ear, slowing audio down without changing pitch, viewing the waveform, looping difficult sections, and navigating quickly while practicing or transcribing.

Features

• waveform display
• loop region selection and repeat playback
• pitch-preserving speed control
• support for mp3, flac, wav, ogg, aac, and m4a

WIP

• instrument audio separation is currently work in progress
