Changelog
What changed in each SoundPipe release, from new features to performance fixes.
Every SoundPipe release, newest first. Updates arrive automatically through the in-app updater (SoundPipe menu, Check for Updates…), or grab the latest from the download page.
Cleaner shutdown of background helpers
- Fixed a background helper occasionally staying alive after its device or source was removed, which could keep capturing or leave a second copy of audio playing until the Mac was restarted.
App captures follow the app
- An app capture now keeps working after the app quits and relaunches. Previously the capture had to be removed and added again.
- While a captured app is not running, SoundPipe simply waits for it.
Steadier app capture with Bluetooth headphones
- Fixed app and system capture crackling and dropping out when Bluetooth headphones were the Mac's current output, most noticeably while their microphone was also in use.
Multichannel routing without a Pass-Thru source
- Fixed sources wired to channels 3 and above going silent on devices whose Pass-Thru source had been removed. Every channel now routes as drawn regardless of which sources the device has.
Better multichannel routing
- Monitors and sources now follow the full channel layout of the devices they connect, so surround devices and multi-output interfaces route exactly as wired.
- Fixed a rare case where a temporary error from the license server could deactivate a valid license.
- Updates now take effect immediately after installing, with no reinstall needed.
Fixed muffled app capture on systems with third-party virtual audio devices
- Fixed application and system audio capture sounding muffled and washed out on Macs where a third-party virtual audio device (such as Background Music) holds the system sound-effects output. macOS used that device as the capture's timing reference, and a misbehaving one could deliver the captured audio at the wrong pace or silence it entirely. Capture timing now always comes from a physical output device.
- As a safety net, SoundPipe now measures the true rate of incoming captured audio and corrects the conversion automatically if the system ever misreports it, noting the correction in the service log.
Faster updates and easier wire selection
- Updates that don't change the audio driver no longer reinstall it, so most updates skip the admin prompt and the brief system-audio pause.
- Routing wires are now selectable by clicking anywhere along the wire, not just at the ends.
Lower idle CPU
- Cut the app's idle CPU use from around 13% to around 3% by eliminating unnecessary window redraws.
A properly attributed background service
- The background service now appears under the SoundPipe name in System Settings → General → Login Items & Extensions, instead of as an anonymous item.
- Documented where to find your license key after purchase, in the docs and the site FAQ.
Smoother audio under load, and licenses go on sale
- Audio no longer skips when the CPU is under heavy load: buffers now adapt to the conditions instead of assuming an idle machine.
- Volume changes apply instantly without restarting the audio path, so there's no glitch while you drag a slider.
- Dragging a volume slider no longer redraws the entire window, cutting CPU use during adjustments.
- If the trial runs out while audio is flowing, the app now opens to explain the noise overlay instead of leaving you guessing.
- Fixed the trial timer occasionally resetting after the background service restarted.
- Buying a license is now live on the site.
Meters that always move
- Output meters now move even when no app is actively listening to the device.
Capture fix for notarized builds
- Fixed hardware and microphone capture being silently denied in notarized builds.
License activation and these docs
- License keys now activate through a signed license service and keep working offline for 60 days at a time.
- Launched this documentation section.
First public releases
- Virtual audio devices, app and system audio capture, hardware routing and monitoring, per-channel volume, live meters, and the free trial.
