The 70% rule
If you can’t play it cleanly at 70% tempo, you’re not ready to speed up. Drop to 60%. Loop four bars, not the whole tune. TempoLab exists so you don’t waste reps on vanity speed. ---
Mark the money beats
Before you touch EQ or reverb, mark where the kick lands, where the vocal breathes, where the guitar slides. Your future self will jump there in one tap instead of scrubbing blind. ---
Loop small, win small
A two-bar loop beats a thirty-two-bar loop for muscle memory. Set A just before the downbeat, B on the last sixteenth you keep rushing. ±10 ms matters — your ear feels phase before your brain names it. ---
Pitch is for comfort, not cheating
Transpose down for morning warmups, up to test if a part still speaks when you’re tired. If you’re learning a cover, practice in the original key at least every third session so you don’t surprise yourself at the gig. ---
Vinyl mode has a vibe
When you link tempo and pitch, you get that sampler/record feel — useful for creative practice, not just transcription. Try it on a soul sample: slow down and hear the harmonics move together. ---
EQ while you practice, not after
Cut 200–400 Hz if the guitar mask is hiding the kick. Boost 3–5 kHz lightly to hear pick attack on acoustic parts. You’re not mastering — you’re making the part audible at low tempo. ---
Practice mode = honest reps
Set start 65%, end 95%, small steps. The day you fail is data: note the % and loop that bar again tomorrow. Speed is a side effect of accuracy. ---
Tap tempo before you argue BPM
Two producers, two numbers. Tap the groove — swing lies to the grid. Use metronome after you agree on feel. ---
Frequently asked questions
Quick answers about features, privacy, and billing.
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.
Is it free?+
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.
