BlackBox Audio Recorder
BlackBox is an always-on audio recorder for macOS. It runs quietly in your menu bar, continuously capturing audio from any input device and saving uncompressed WAV files to your Mac.
Built for musicians, podcasters, sound designers, and anyone who never wants to miss a moment of audio.
$49.99 one-time, no subscription. Requires macOS 15.0 (Sequoia) or later.
Features
