Rogue Amoeba, one of the best software houses for the Mac has just released Piezo, which lets you record audio from any app on you mac. Sounds simple right – that’s the point. Recording audio has always been somewhat of a tricky task, especially on a computer because you have so many apps and tasks running. Often times, while recording, you can contaminate a clean audio recording simply by opening up an app that plays a sound or if someone decides to Skype you. Recording on a computer was never easy and now it is….and it’ll only cost you $10.
