To change a steady 120 BPM song to 100 BPM, enter 120 as the original and 100 as the target. The tool sets speed to 100 ÷ 120 while keeping pitch unchanged. You can detect an estimated original BPM or enter it yourself.
GOOD TO KNOW
Using the Speed changer.
How do I slow down music without changing pitch?+
Open a song and lower the speed while it plays. Keep the pitch control at zero to preserve the original key. Try 0.8× to practice a difficult phrase, then gradually return to normal speed.
How does playback speed affect BPM and duration?+
At 0.5×, a steady 120 BPM song plays at about 60 BPM and takes twice as long. At 1.5×, it plays at about 180 BPM and takes two-thirds as long. The key and BPM finder still reports estimates for the original recording.
Can I save a slowed-down song?+
Yes. Choose MP3 or WAV beside Download to save the adjusted audio. Longer recordings and slower speeds take more time and device storage to export. No account or audio upload is needed.
