TempoLab: Music Practice

Change tempo and pitch, loop sections and separate voice offline.

Practice music at your own pace with TempoLab.

Open a local audio file and adjust tempo from 50% to 200% without changing pitch, or transpose up to 12 semitones. Repeat an A–B section and set exact boundaries with minute, second and millisecond wheels.

Save named sections for each recording. Use progressive practice to increase the tempo after a chosen number of repetitions. Keep playback going in the background or with the screen off.

Shape your sound with a five-band equalizer and level control. Export the whole recording or a selected section as 16-bit WAV with the current tempo, pitch and equalizer settings.

Separate voice and instrumental from a 0.5–20 second section, entirely on your device, using Spleeter. Compare the results and save WAV files. Separation quality depends on the recording and may include artifacts. Keep the app open while processing.

English, Romanian and Spanish. No account required. Audio processing works offline. Import supports mono/stereo files up to 30 minutes / 512 MB decoded audio; format support depends on Android codecs. Android 10+ on ARM64 devices.
