Pick the route that matches the file you actually need. Updated August 2026.
For microphone-only audio, use QuickTime Player. For a screen video with desktop audio, use OBS Studio. For a free audio-routing setup, use BlackHole. If you want one local audio file containing Mac audio, a microphone or both, use a recorder built on Apple's native capture APIs.
Short answer
The important distinction is between an input and the sound playing on the Mac. QuickTime's audio recorder can select a microphone or another input device, but it does not offer Mac system audio as a source. Modern Mac apps can capture system audio through Apple's ScreenCaptureKit or Core Audio APIs after you grant permission, so a virtual audio driver is no longer the only route.
Built in
This is the shortest path for voice notes and external inputs. Apple's own QuickTime guide lists microphone and quality choices, but no system-audio source. Apple's Screenshot toolbar has the same limitation for audio: its recording option is a microphone. Use it when the screen matters and microphone audio is enough.
Free and capable
OBS is the strongest free option when you need scenes, video, streaming, separate sources or per-application control. Its official macOS audio guide confirms that current versions can capture all desktop audio or a chosen app without a virtual device. The tradeoff is an interface designed for production and streaming rather than a quick audio-only take.
Free audio routing
BlackHole is open source, supports Intel and Apple silicon, and works with applications that can record an ordinary input device. Its own documentation explains the routing: the sending app outputs to BlackHole and the recording app receives from it. A Multi-Output Device is what lets you keep hearing the sound while it is routed to the recorder.
Choose this route when zero cost and routing flexibility matter more than setup time. Remember to restore your normal output device afterwards.
Audio only, no routing
PX7 Audio Recorder captures Mac audio through Apple's native APIs and can combine it with one Core Audio input in the same recording. Choose Mac audio, microphone or both, watch the live meters, and save WAV, AIFF, CAF or M4A. It does not install a virtual driver, upload audio or require an account.
It costs €19 once after a seven-day trial and requires macOS 14.2 or later on Apple silicon. It is not the right choice if you need Intel support, per-application source selection, separate tracks, streaming scenes or a free tool; use BlackHole or OBS for those cases.
Homebrew install from the public PX7 cask:
brew install --cask px7digital/tap/px7-audio-recorder
Before the real take
This catches the failures that matter: the wrong input, a silent system source, feedback, clipping or an unexpected save location. Also make sure you have permission to record calls, meetings and copyrighted material; consent and copyright rules depend on what and where you record.
Quick answers
No. QuickTime Player's audio recorder accepts a microphone or another audio input, but it does not offer the sound playing on the Mac as a source.
Yes. On current macOS versions, apps can capture system audio through Apple's native audio APIs after you grant permission, without installing or routing through a virtual device.
Yes. OBS Studio 30 or later on macOS 13 or later can capture all desktop audio or one application with its macOS Audio Capture source.
Use an app that combines a native system-audio source with a Core Audio input, or combine BlackHole and the microphone in an Aggregate Device. Test both meters before the real take.
