Frequently Asked Questions
Does it work in background tabs?
Yes. TuneLab uses the Web Audio API clock, which keeps accurate time even when the tab is in the background — unlike JavaScript-based metronomes that drift.
What genre tempos should I practice at?
Common ranges: Hip Hop 85-95, House 120-130, Techno 128-140, Drum and Bass 170-180, Trance 135-145.
Will my settings be saved?
Yes. Your BPM and time signature persist in your browser's local storage. Close the tab and come back — your last settings are restored automatically.
