An overdub-first multitrack recorder: play, record, play it back, and record more on top — up to 8 layers — then export. It measures your actual room and uses that to make layers sit together.
To record your takes and to play a short calibration tone and measure your room. Audio stays on your device; nothing is uploaded. You can change this in Settings → Privacy & Security → Microphone.
Sample-accurate layering needs a stable, low-latency path. Wired headphones = GREEN (full sample-accurate overdub). Built-in speaker or Bluetooth/AirPods = RED — timing isn’t guaranteed and earlier layers may bleed into the mic, so sample-accurate overdub is disabled on those routes. Plug in wired headphones for the best results.
A brief, level-limited sweep the app plays through the speaker and records back to measure your room’s character (reverb and tone). It’s band-limited and capped for speaker and hearing safety.
Entirely on your device. OverDub collects nothing, has no account, and never transmits your audio or projects. See the Privacy notice.
WAV and AAC (.m4a), via the iOS share sheet. Exports are loudness/true-peak managed so they’re safe for sharing and streaming.
That’s intentional — changing the audio route mid-take ends and flags the take rather than silently continuing across the discontinuity. Keep the truncated take or re-record.
Email support@overdubapp.com with “Bug” or “Feature” in the subject. Steps to reproduce help a lot.
