How to record streaming audio on a Mac
A live set that will never be uploaded, a webinar that expires, internet radio, a broadcast in a tab. If your Mac can play it, your Mac can record it, at full quality.
Why downloading is often not an option
Live streams frequently exist only while they happen. There is no file to download, the platform offers no replay, or the replay is cut. The only copy that will ever exist is the audio your Mac is playing right now.
Recording that playback is a capture problem, not a download problem, and it works the same for every source: browser tabs, apps, players, anything.
The clean way to capture it
AirCheck records your Mac's system audio through Apple's ScreenCaptureKit. No virtual driver in the audio stack, no browser extension, no rerouting; you grant permission once and keep hearing everything normally while it records.
- Full quality. Lossless 24-bit capture at the system rate, taken before the speakers, so a quiet volume knob does not ruin the take.
- Unlimited length. An all-night broadcast fits; disk space is the only bound.
- Dropout recovery. Device hiccups mid-stream do not split or lose the recording.
- WAV or MP3 out. The take converts when it stops and drags out of the app as a normal file.
If your Mac plays it, AirCheck records it.
One-off payment. Fourteen-day refund, no questions asked.
A note on rights
Recording something for yourself and redistributing it are different things. Keep personal recordings personal, and check the terms of the service you are capturing from if you are unsure.
