Detect a song's current tempo, enter an exact target BPM, preserve the original pitch, preview the result, and export the adjusted audio.
Drop a song, loop, backing track, or recording here to detect and change its BPM, or or import from:
Confirm the detected tempo, enter the BPM you need, and keep the original pitch.
A BPM changer adjusts a song from its current beats-per-minute value to a specific target tempo. Instead of choosing only a general speed percentage, you can work with the exact BPM required by a rehearsal, backing track, mix, routine, or production.
The tool estimates the source tempo, lets you correct or replace that estimate, calculates the required speed change, and keeps the original pitch while the duration changes.
Analyze the selected track and start with an estimated current BPM.
Correct the source tempo and enter any target from 20 to 400 BPM.
Fix common tempo-reading differences with one click before choosing the target.
Hear the adjusted tempo and export WAV, MP3, M4A, FLAC, or OGG without transposing the song.
Move from the detected tempo to an exact BPM in three steps.
Add a song, loop, backing track, or recording and review the estimated current BPM.
Edit the source value when needed, use Half BPM or Double BPM for common corrections, and enter the new BPM.
Listen to the tempo-adjusted preview, choose WAV, MP3, M4A, FLAC, or OGG, and process the complete file.
Exact BPM control is useful when a percentage alone is not specific enough.
Prepare a song at the rehearsal or performance tempo used by a band, singer, or instrumentalist.
Set tracks to a consistent pace for choreography, fitness classes, warm-ups, or practice sessions.
Compare how a song, beat, or arrangement feels at nearby BPM values before committing to a final tempo.
Create a tempo-matched reference for DJ preparation, edits, transitions, and timing experiments.
Both tools preserve pitch, but they use different ways to define the new speed.
| Tool | Input | Result | Choose it when |
|---|---|---|---|
| BPM Changer | Current BPM and target BPM | Exact requested tempo | You know the BPM the track must reach |
| Tempo Changer | Speed percentage | Relative speed change | You want audio slower or faster without a required BPM |
| BPM Finder | Audio file only | Tempo estimate | You need to measure BPM without changing the audio |
Upload the song, confirm its current BPM, enter the target BPM, preview the change, and export the adjusted audio.
Yes. The BPM changer adjusts tempo and duration while keeping the song in its original musical key.
The detected BPM is a starting estimate. Complex rhythms, quiet intros, syncopation, and half-time grooves can require manual correction.
Some rhythms can be counted at half-time or double-time. Use the Half BPM and Double BPM buttons to correct the source value before setting the target.
Current and target BPM values can be set from 20 to 400. The resulting speed change is limited to 50% through 200% for practical browser processing.
The BPM-adjusted result can be exported as WAV, MP3, M4A, FLAC, or OGG.
Yes. Increasing BPM shortens the track, while decreasing BPM makes it longer. The new duration is shown before export.
No. The built-in BPM detection, preview, and audio processing run in your browser.
