Standard guitar E2–E4 and bass E1–G2 shown for reference. In-tune window is ±5 cents. Allow microphone access when asked; turn off any browser noise suppression for best tracking.
Solo instrument (you playing into the mic)? Use "Transcribe directly" — free, on-device, works on iPhone. "Separate full mix" isolates vocals/drums/bass/guitar/piano first (needs the Riffer worker + Replicate).
Record a riff, then loop it while you practise over it — the metronome can run at the same time. Slow it to 50–75% to learn fast passages; pitch stays true with the lock on (untick for tape-style pitch drop). Overdub stacks layers on top — the first recording sets the loop length, and overdubs play the loop at 100% speed while you record. With snap on, the loop length rounds to the metronome grid — set the metronome BPM first and record with it running for tightest results. Use headphones to avoid the mic picking up the loop.
Device names appear after you've granted mic permission at least once (use Refresh). Output selection works in Chrome/Edge on desktop; iPhones always use the system output. Settings are remembered on this device. On iPhone: the first tap anywhere activates audio (a silent keeper track holds the session open, so the silent switch no longer mutes the metronome/chime). Software volume is restricted by iOS, so the loop volume slider re-renders the audio when released; overall loudness is the side volume buttons.
