Record It allows you to record audio on Mac. You can record system sound, microphone sound and any other audio devices' sound.
Please note that to record audio, there needs a plugin Record It Audio Device which is a free extension that enables you to capture system sounds on your Mac. It acts as a virtual audio input device and sends the sound from music, videos, and system alerts that you would normally hear through your speakers to the input channel so that it may be recorded by screen capturing software.
