Online Tempo Changer: Speed Up Songs for Workouts
Research shows that high-tempo music (120-140 BPM) improves athletic performance. It helps runners maintain a consistent cadence and pushes gym-goers to lift harder.
But what if your favorite song is a slow ballad at 90 BPM? You don't have to delete it from your playlist. You just need to change the tempo.
The BPM Hack
By increasing the speed of a track by 10-20%, you turn a relaxed radio hit into high-energy gym fuel.
- Original: 100 BPM (Moderate walking pace).
- 1.25x Speed: 125 BPM (Jogging pace).
- 1.5x Speed: 150 BPM (High-intensity sprinting).
How to Create a Custom Workflow Playlist
- Gather Tracks: Pick the songs that motivate you.
- Use the Tool: Open our Audio Speed Changer.
- Boost Speed: Set the speed to
1.2or1.3. - Preserve Pitch: This is crucial. Ensure "Keep Pitch" is checked so the vocals sound natural, just faster (like a radio edit).
- Download: Save the new MP3s to your phone.
Why Not Just Use "Nightcore"?
Nightcore (fast + high pitch) is fun, but for a 30-minute run, listening to chipmunk voices can be annoying. A proper Tempo Changer keeps the artist's voice sounding authentic, just more energetic.
