No Audio MIDI Setup required
BlackHole gives you a virtual device and leaves the wiring to you: multi-output devices, aggregate devices, and sample-rate matching in Audio MIDI Setup. SoundPipe does all of that from one window.
SoundPipe vs BlackHole
BlackHole is an excellent open-source virtual audio driver — but it is only a driver. SoundPipe adds the app around it: a routing UI, volume control, monitoring, and a one-click install.
BlackHole gives you a virtual device and leaves the wiring to you: multi-output devices, aggregate devices, and sample-rate matching in Audio MIDI Setup. SoundPipe does all of that from one window.
With BlackHole, monitoring your own routed audio means building a multi-output device by hand — and you lose volume-key control in the process. SoundPipe routes to your headphones or speakers directly.
BlackHole passes audio through at a fixed level. SoundPipe gives every channel its own volume control so you can balance sources without touching the apps producing them.
BlackHole requires every device in the chain to run at the same sample rate, and mismatches produce silence or distortion. SoundPipe works with any sample rate and keeps devices in sync automatically.
Full credit where due: BlackHole is free, open source, widely used, and rock solid. If you're comfortable configuring macOS audio by hand and don't need volume control, use it. This table shows what SoundPipe's $10 buys you on top.
| Feature | SoundPipe | BlackHole | Notes |
|---|---|---|---|
| Virtual audio devices | Yes | Yes | Both create virtual devices other apps can read and write. |
| Free and open source | No | Yes | BlackHole is GPL-licensed and free. SoundPipe costs $10. |
| One-click install | Yes | Partial | BlackHole ships an installer, but all routing setup afterwards is manual. |
| Feature | SoundPipe | BlackHole | Notes |
|---|---|---|---|
| Graphical routing UI | Yes | No | BlackHole has no UI at all — configuration happens in Audio MIDI Setup. |
| Per-channel volume | Yes | No | BlackHole passes audio at a fixed level. |
| Monitoring without multi-output workarounds | Yes | No | With BlackHole you build a multi-output device by hand to hear routed audio. |
| Automatic sample-rate handling | Yes | No | BlackHole needs every device manually set to the same rate. |
| Low latency | Yes | Yes | Both are fast. SoundPipe stays under 15 ms; BlackHole adds effectively zero latency as a passthrough driver. |
Try SoundPipe free and see if the $10 is worth the saved fiddling. (We think it is.)
