Pitch & Speed changes the key and the tempo of any song, separately. Slow down a fast solo without changing its pitch, transpose a song to suit your voice or instrument, and loop the bar you are learning.
Pitch: transpose up or down by up to 24 semitones, and fine-tune in cents (±50) to match a detuned recording. Speed: from 25% to 400% of the original, with the pitch unchanged, or link the two like a record player.
Loop any section with A-B markers on the waveform. The app detects the key and the BPM of the song and shows the new ones after your changes.
Effects: 10-band equaliser, preamp, balance, and reduce vocals to sing or play along. Open MP3, M4A, WAV, FLAC and OGG files, or the audio of a video. Export the song or just the loop as M4A or WAV.
Free, no ads, no account, no in-app purchases. Works offline and collects no data: your songs never leave your device unless you share them. For Android, iPhone and Windows.
I'm an independent developer. I made a simple practice tool for playing along with recordings: change the key and the tempo of a song separately, and loop the part you are learning. I wanted it free, with no ads, no account and no data collection, working offline on Android, iPhone and Windows.
