01 / Choose
Connect a destination
Select Live audio from other apps, then choose an installed AUv3 effect or sampler with an audio input.
Live audio routing for iOS
Move sound between apps.
Patchbay sends permitted live audio from another app into a compatible AUv3 effect or sampler. Capture a sound, stop the incoming feed, and listen to the result without rebuilding your setup.
Designed for iPhone and iPad running iOS or iPadOS 27 or later.
PATCHBAY
01Source
Live audio from other apps
02Destination
Your AUv3 sampler
A short path from source to sample.
Patchbay hosts the destination Audio Unit and keeps it available between takes. Apple’s system prompt remains in control of when capture begins.
02 / Capture
Approve and record
Open the destination controls, start recording, and approve Apple’s screen-capture prompt before playing your source.
03 / Listen
Stop and audition
Finish the sample, stop incoming audio, and listen immediately. The same destination stays open for the next take.
Local by design
Your audio stays in your audio workflow.
Patchbay processes captured audio in memory and routes it to the Audio Unit you select. It does not create an account, upload audio, request microphone access, or save screen video.
No analytics
No advertising
No developer cloud
Built around the way iOS handles audio.
Patchbay works within Apple’s capture controls and AUv3 extension system. Clear boundaries keep the workflow predictable.
System consent
You decide when capture starts
iOS asks for approval each time. Patchbay cannot bypass or dismiss the system prompt.
AUv3 hosting
Use compatible audio tools
The destination runs as an Audio Unit inside Patchbay, separately from its standalone app.
Protected media
Capture rules still apply
Protected content and apps that disallow capture may provide silence. Use audio you have permission to record.
