Can I use a Spotify or Apple Music playlist?

MUSIC THAT FITS YOUR STRIDE
Keep a favourite song and adjust its pulse to a running rhythm you already find comfortable. Prepare a downloadable version before you head out.
Use one audio file from your device, up to 5 minutes and 100 MB. This prepares a fixed-speed download; it does not follow your footsteps or connect to streaming playlists.
Prepare your running track for free
The audio tool opens on the Pitch Tempo home page.

Choose a comfortable cadence first, decide how the musical pulse will line up with your steps, then adjust a suitable song’s BPM. Export that fixed-speed version before your run. This is a way to prepare music you already own, rather than a player that changes speed as you move.
The useful starting point is a track with a clear, steady beat near the pace you want. A song you struggle to follow while standing still is unlikely to become an easy rhythm cue simply because its detected BPM matches a number.
BPM counts musical beats. Running cadence is commonly expressed as steps per minute, counting both feet. You can choose to take one step per musical beat, or two steps per beat if that feels natural with the song’s pulse.
| Chosen cadence | One step per beat | Two steps per beat |
|---|---|---|
| 160 steps/min | 160 BPM | 80 BPM |
| 170 steps/min | 170 BPM | 85 BPM |
| 180 steps/min | 180 BPM | 90 BPM |
These are arithmetic examples, not recommended cadences. There is no target in this guide that every runner should adopt. Use a rhythm that suits you; the audio tool does not measure your gait, prescribe training or calculate a running pace in minutes per kilometre.
An automatic detector may describe a song as 85 BPM while you count a convincing faster pulse at 170. Listen for the pulse you intend to follow before treating the reading as a mistake or doubling the audio speed.
Suppose your chosen rhythm is 170 steps per minute and your song has a usable pulse at 160 BPM. For one step per beat, the tempo setting is 170 ÷ 160 × 100 = 106.25%. Keep pitch at 0 semitones if you want to retain the original key.
A different track at 80 BPM could use the same 106.25% setting to become 85 BPM, with two steps per beat. Decide which relationship you are using before doing the calculation. Setting an 80 BPM file to 170 BPM would require 212.5%, beyond Pitch Tempo’s 150% maximum and unnecessary for this two-steps-per-beat example.
Small changes often keep more of the familiar character of a recording. A large adjustment can make the voice or percussion sound less natural. If the result loses the quality you liked, select another song closer to the required pulse.
Open the music BPM finder and tempo controls, upload a track and select Find pitch / tempo. Compare the estimate with the beat you hear.
Select Change pitch / tempo. Type the tempo percentage in the numeric field and leave pitch at zero. Listen preview applies it to the first 20 seconds of source audio.
Choose Download full track and an output format. Download the result, then check that your intended music app opens it and that the pulse stays usable beyond the introduction.
A 20-second opening may include an ambient introduction rather than the main beat. Preview cannot jump to a later section; check the complete exported file before relying on it. The service does not assemble songs into a continuous workout mix or insert transition beats.

No. The download plays at the tempo you selected. It does not use motion sensors or adjust in real time.
No. Speeding up the whole recording keeps its relative tempo variations. Choose a steady source if you need a consistent pulse.
Compare opening previews before exporting. A full export completes that chat; another full version needs a new upload and uses the normal new-chat allowance. The service overview explains the workflow and limits.
Bring a song with a clear, steady pulse and a target you have chosen. Find its BPM, make a modest adjustment and save a version for your next run.
