Recording audio on the Mac just got a little easier thanks to WavTap, a nifty audio utility created by Github user Patrick Ellis. Spotted by Peter Kirn of Create Digital Music, the tool lets you record audio on your Mac using a keyboard shortcut. You can use the customizable shortcut to both start and stop the recording on the fly.
WavTap is a fork of Soundflower, an OS X system extension that lets you pass audio from one application to another. Besides being a single channel device, Soundflower also acts as a 16-channel device, which means WavTap can potentially record input from a multichannel rig.
WavTap is open source and available for free on GitHub. There's no installer included in the app, so users must have Xcode installed and know how to install an app using Terminal.
