What is TempoLab Pro?

A mobile app for practicing with your own audio files: change tempo and pitch, loop sections, add markers, use EQ/reverb/metronome, and export results. Built for musicians, singers, and anyone who learns by listening.

Which platforms are supported?

iOS and Android. iPad and large Android tablets get an enhanced layout with side navigation.

Yes to download and practice. Ads appear in the free tier. A one-time Remove Ads purchase unlocks Premium features.

What languages are supported?

17 locales including English, Hebrew, Arabic, Chinese (Simplified & Traditional), French, German, Italian, Japanese, Korean, Portuguese (BR & PT), Russian, and Spanish.

What file formats can I import?

Common formats such as MP3, M4A, WAV, and FLAC (device-dependent). If import fails, try another format or a non-DRM copy.

Why can’t I import my Apple Music / Spotify song?

Streaming downloads are often DRM-protected. TempoLab Pro only works with files you have rights to use locally — recordings you made, purchased downloads without DRM, or stems shared with you.

Does changing tempo change pitch?

Not by default. Tempo and pitch are independent. Vinyl mode links them intentionally for creative/record-style playback.

How precise is looping?

You can nudge loop points by ±10 milliseconds — enough to align by ear to transients and grid.

What is formant correction?

When shifting pitch on vocals, formant processing helps the voice keep a more natural character instead of sounding overly thin or heavy.

What’s the difference between waveform and spectrogram?

Waveform shows amplitude over time; spectrogram shows frequency content. Both help you navigate — use whichever reads faster for your material.

Does Practice mode increase tempo automatically?

Yes. You set start speed, end speed, and step size; the app ramps speed during the session.

Is there a metronome?

Yes — use it alongside your track or with tap tempo to match BPM.
