Patch Bay
A visual, low-latency audio routing matrix for macOS. Tap individual apps without interrupting playback, host VST3 plugins inline, and patch signals cleanly between virtual CoreAudio buses and hardware interfaces.

Built like hardware. Wired for macOS.
Designed around a visual node canvas and a native C++/Swift audio engine so every connection stays predictable under studio load.

Inline VST3 Hosting
Scan your installed VST3 plugins and patch EQ, compression, limiters, or room correction directly inside any signal path.
Node-Based Patchbay
Drag patch cables between app taps, hardware microphones, interfaces, VST3 inserts, and virtual outputs in one clear workspace.
Tunable Ring-Buffer Latency
Lock-free C++ ring buffers keep audio glitch-free with per-session latency controls tuned for live monitoring or broadcast.

Frequently Asked Questions
Does Patch Bay require restarting audio apps when routing?
No. Patch Bay uses native macOS process tap capture so you can tap audio from running applications without interrupting playback, and route through the CoreAudio HAL virtual driver into your DAW or broadcast software.
Can I run VST3 plugins on system or app audio?
Yes. Patch Bay includes an integrated VST3 scanner and host, allowing you to insert VST3 effects directly between any audio source and output destination.
