Can I slow down an MP3 and save the result?
Yes. Upload your MP3 on the home page, select a slower tempo and export the full recording. MP3 is convenient for a practice playlist; other output choices are explained in the format guide.
MORE TIME FOR EVERY PHRASE
When a recording moves faster than you can follow, a slower practice version gives you time to hear the notes, understand the rhythm and play along in the same key.
Prepare a downloadable practice file from audio up to 5 minutes and 100 MB. Preview starts with the first 20 seconds; selected-section looping is not available.
The audio tool opens on the Pitch Tempo home page.

Use the free tempo changer on the Pitch Tempo home page. Upload your audio, choose Change pitch / tempo, leave pitch at 0 semitones and set tempo below 100%. Request a preview, then download a slower version of the whole recording for practice. The available speed range is 50% to 150% of the original.
You do not need to identify the song’s BPM first when working in percentages. For example, 80% means four-fifths of the original pace, whatever its starting tempo.
A fast guitar run can blur into a single gesture before you have worked out its notes. A piano passage may leave too little time to coordinate both hands. For a singer, the difficulty might be the timing of consonants or an entrance between quick phrases. A slower recording gives you more listening and response time while keeping the notes at their original pitch.
Start with a moderate reduction, such as 80%, and listen again. If you still cannot follow the passage, choose a lower setting within the available range. If it has become easy to follow, try moving closer to 100%. There is no required practice percentage: the useful setting depends on the phrase and what you are working on.
Slowing the audio does not isolate an instrument, identify the notes or generate tablature. You still work out the part yourself, using the recording as a clearer reference.
Choose a short musical goal, such as following one phrase with steady timing. Work at a manageable pace, then make a small increase when you can repeat it comfortably. If mistakes return, step back and work on the transition that caused them.
| Tempo setting | Approximate BPM | Possible purpose |
|---|---|---|
| 60% | 72 BPM | Listen closely and work out the phrase |
| 80% | 96 BPM | Connect the notes with more fluent timing |
| 90% | 108 BPM | Rehearse near the original pace |
| 100% | 120 BPM | Return to the recording’s original tempo |
This is an illustrative sequence, not an automatic training mode. Pitch Tempo applies one selected speed to an export; it does not increase the tempo on each repetition. Its player also has no adjustable A–B loop. You can replay the finished file or use your own practice player after downloading it.
Choose one useful speed for your next practice session. Making another full version after export requires a new chat and another upload of the original, which uses your new-chat allowance. Before exporting, you can compare different speeds using the opening preview in the same chat.
Visit the home audio tool and select a readable recording no larger than 100 MB and no longer than 5 minutes. Use an audio file such as MP3, WAV or FLAC. Streaming links and song-title lookup are not supported.
After preparation, choose Change pitch / tempo. Set a speed between 50% and 100% for slower practice and keep pitch at 0 semitones. For a named BPM target, first choose Find pitch / tempo to obtain a starting estimate.
Choose Listen preview to process your settings. The source excerpt is the first 20 seconds, or the whole source if shorter. At 80% speed, a 20-second excerpt lasts about 25 seconds. Adjusting either control clears that preview until you request a new one.
Select Download full track, choose an output format and wait for the finished recording. The final player lets you hear the complete result before saving it. If the difficult passage is later in the song, check it here; the short preview cannot select a different section.
Keeping pitch unchanged lets you play along using the same notes, but time stretching can still change the texture of a recording. At larger slowdowns, sharp attacks or sustained sounds may become less clear. Compare nearby speed settings and choose one that gives you enough time without making the phrase difficult to hear.
If the notes themselves sound higher or lower, check that the pitch control is still at 0 semitones. If the rhythm seems uneven, listen to the source: slowing a live performance preserves its timing variations. It does not automatically turn an expressive performance into a perfectly steady beat.
BPM detection may return half-time or double-time interpretations. A percentage change still slows the file by the selected amount. If you are matching a specific metronome marking, check the estimated starting pulse before relying on the calculated target.
Yes. Upload your MP3 on the home page, select a slower tempo and export the full recording. MP3 is convenient for a practice playlist; other output choices are explained in the format guide.
With pitch at 0 semitones, changing tempo preserves the source pitch. An instrument that matched the original should still match the slowed version. This does not correct a source recording that was already outside your instrument’s tuning.
The current editor applies one tempo setting to the entire uploaded file. It does not trim out a solo, loop a selected section or automatically raise the practice speed. The preview always starts at the beginning.
Yes. The five-minute limit applies to the uploaded source. A four-minute recording slowed to 80% lasts approximately five minutes; at 50%, it lasts approximately eight minutes.
No. Guests can create 3 new chats per 24 hours, while free accounts allow 5 per hour and save progress. Keep your downloaded copy for rehearsal: guest audio on the server expires after 24 hours, and account audio after 7 days from the original upload.
Open your audio on the home page, choose a slower tempo and download a full rehearsal version when the settings sound right.
