Pitch Changer & Key Changer

Pitch Changer & Key Changer lets you change the pitch, key and speed of any song or audio file on your phone. Lower the key to fit your voice, raise it to match your instrument, slow a song down to learn it, or speed it up to practise. FREE, NO ADS - Pitch changer: shift any song up or down by up to 12 semitones with simple + and - buttons. - Key changer: the shift is shown in semitones so you always know how far you moved from the original. - Speed changer: from 0.25x to 2x, and changing the speed never changes the pitch. - A-B loop to repeat the part you are practising. - Plays with the screen off, with controls in the notification. - No time limit and no ads at all. PRIVATE AND SIMPLE - Pick a file from your phone with the normal file picker. No account, no sign-in, no media library permission. - Works offline. Your music never leaves your device. - MP3, M4A, WAV, FLAC, OGG and more, as supported by your phone. PRO, ONE-TIME PURCHASE (NO SUBSCRIPTION) - Save the changed song as a new audio file. Your first export is free, so you can try it before you decide. - Fine-tune the pitch in cents. - Save presets for your favourite pitch and speed settings. Pay once, keep it. No weekly or yearly plans. WHO IT IS FOR Singers who need the right key, guitar and piano players practising with slowed-down songs, musicians transposing a backing track, dancers and teachers adjusting the tempo of a track. This app changes audio files you already have on your phone. It does not download or stream music. Questions or ideas? Write to [email protected].
