USING AIRPODS?
We’re trying wireless live monitoring, too. It’s experimental: Bluetooth delay may make singing or playing uncomfortable. Record & replay gives you another way to listen.

Good to know.
What do I need?
An iPhone and headphones. Wired headphones are the recommended start for live monitoring. Audio interfaces need connected headphones. AirPods live uses the phone’s microphone and may feel delayed; record & replay is the alternative. Avoid live monitoring through speakers.
Can I keep my music playing?
Humstrum is designed to request audio mixing from iOS. It doesn’t control or capture another app’s music. Compatibility depends on your player, iOS and headphones, and still needs device testing. Music from speakers can be picked up by the microphone.
Is this my “true” voice?
It’s a microphone’s perspective. Your voice also reaches you through your head; Humstrum doesn’t cancel that bone conduction or recreate exactly what every listener hears.
Does my audio stay private?
The app is designed to keep audio on your iPhone, with no account, ads, analytics or cloud audio. One take stays in local cache until replaced, deleted or cleared by iOS, and is excluded from backups. This site has no added analytics or signup form; the host may process access information. Final publisher and support details will be added before release.
