Mcaster1AudioPipe
Broadcast-grade virtual audio routing for creators, broadcasters, and professionals. Create invisible audio cables between any apps on your Mac — no hardware, no hassle, no limits.
v1.2.0-beta.1 — Apple Developer ID signed & notarized. macOS 13 Ventura or later. Apple Silicon native (arm64).
What Is Mcaster1AudioPipe?
Think of it as invisible audio cables running inside your computer.
Virtual Audio Cables
Create named virtual audio devices that show up in your system just like a real microphone or speaker. Send audio from one app to another — silently, instantly, and with zero perceptible delay.
Visual Patch Bay
Drag-and-drop cables between devices in a gorgeous 3D patch bay interface. See your entire audio routing at a glance — just like a real studio patch panel, but on your screen.
Zero-Latency Routing
Built on lock-free ring buffers that move audio at sub-millisecond speeds. Your listeners will never hear a gap, a glitch, or a delay. Broadcast-grade performance, period.
Per-Pipe Controls
Every virtual cable gets its own volume, mute, and real-time level meters. Monitor peak levels, watch for clipping, and adjust your mix without ever leaving the app.
Up to 16 Pipes
Run up to 16 simultaneous named audio pipes. Create separate routes for music, voice, sound effects, talkback, mix-minus — whatever your workflow needs. Name them anything you want.
No Reboot Required
Install the driver and start routing audio immediately. No kernel extensions, no rebooting, no complicated setup wizards. It just works — on both macOS and Windows.
How It Works
AudioPipe sits between your apps, connecting audio outputs to audio inputs through virtual devices.
For Broadcasters
Route your media player directly into your streaming encoder without any external hardware. Perfect for internet radio, podcasts, and live shows. Track metadata flows through automatically for stream titles.
For Content Creators
Separate your game audio, voice chat, music, and alerts into individual virtual cables. Mix them independently. Record or stream exactly what your audience should hear — nothing more, nothing less.
Part of the Mcaster1 Broadcast Stack
AudioPipe is the audio wiring that connects the entire Mcaster1 ecosystem together.
| Product | What It Does |
|---|---|
| Mcaster1AMP | Desktop media player — plays your music and sends it into AudioPipe |
| Mcaster1AudioPipe | Virtual audio routing — the invisible cables connecting everything (this product) |
| Mcaster1DSPEncoder | Broadcast encoder — captures audio from AudioPipe and streams it live |

Use them together for a complete end-to-end broadcast chain, or use AudioPipe standalone with any audio software you already own.
