Dave Godowsky

Set your tempo and bar count, then hit Record — or leave Bars blank to record endlessly and stop whenever you like. Your browser will ask for mic access.

Using AirPods? Keep them for listening only and set the Microphone above to your device's built-in mic (Deja VU picks it automatically when it can). Recording through the AirPods' own mic forces Bluetooth into phone-call mode — that's the muffled "filtered" sound — and makes latency worse. For the tightest timing, wired headphones are still the gold standard.

Shortcuts: R record loop · O riff/overdub · Space play/stop. Each riff session — from when you start to when you stop — is saved as one take below.

BPM mode (best for fitting the grid): type the BPM and Bars above, then drag anywhere on the wave to slide a perfectly-sized loop window over the clip — the gridlines show every beat. Free range: drag the green (start) and red (end) markers to any two points, any length — the loop cycles between them, and tempo is worked out from the region and your bar count. Zoom in for fine placement — markers snap to zero-crossings for a click-free splice. You can reopen this editor anytime with Edit clip on the Loop track.

WAVs are mono, 16-bit, at your device sample rate — drop them straight into any DAW. All loop-length files line up bar-for-bar. The mixdown applies your track gains — cranked into the red, it clips just like playback. Stems export raw so you keep full range in the DAW.
