Menu bar audio recorder
Pick Music, a browser or a video call and TapeOut records that app alone - no notification pings, no other tabs. Or leave one app out and record the rest.

Choose what goes into the file before you press record. TapeOut finds an app's helper processes too, so a browser's audio is caught even though it plays from a separate process.
A lecture in your browser, a podcast app, a game - recorded on its own, while everything else keeps playing.
Record a call without the music playing in the background, or a game without your chat app's pings.
Whatever the computer plays, mixed down to one stereo file.

The popover shows the source, the elapsed time and a live level meter, so you know the signal is there before the take is over.

Pick the format per job. Finished recordings are listed with their source and length - drag one straight into an editor, notes or a message.
Requires macOS 14.4 or later · English, Deutsch, Español, Русский, Українська · $6.99 one-time, no subscription. Please respect copyright and other people's rights in what you record.
