Slow down a fast solo without changing its pitch, move a song to your key and loop the bar you are learning. No ads, no account, works offline. 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 until it sits under your fingers. Built for musicians who practise with recordings: singers, guitarists, bassists, pianists, drummers, students and teachers. CHANGE THE PITCH • Transpose up or down by up to 24 semitones, in steps of one semitone • Fine-tune in cents (±50) to match a detuned recording or an instrument that is not at A440 • The tempo stays the same while the key changes • Natural voice: keeps voices sounding natural when you shift the pitch CHANGE THE SPEED • From 25% to 400% of the original speed • The pitch stays the same while you slow down or speed up • Link pitch and speed: works like a record player, faster sounds higher LOOP ANY SECTION • Set an A-B loop and repeat a riff, a chorus or a tricky passage • Drag the A and B markers on the waveform to adjust the loop • Tap or drag the waveform to jump anywhere in the song • Skip back or forward 5 seconds KEY AND TEMPO DETECTION • Detects the key and the BPM of the song • Shows the new key and tempo after your changes, so you always know what you are playing in EFFECTS • 10-band equaliser (±12 dB) with Flat, Bass, Voice and Bright presets • Preamp and left/right balance • Reduce vocals: removes the centre of the stereo mix, where lead vocals usually are, to sing or play along.
