The AudioWow works using both hardware and software to upgrade your recording game. On the hardware front, it packs an external audio card that runs the digital signal processing and a 6mm studio-grade condenser microphone that trumps the one you’ve got built into your smartphone. The secret sauce for the AudioWow, however, lies in the app, which has more pro-features than I could possibly count. Not only does the AudioWow app let you record podcasts and interviews, it also lets you record calls. The studio-grade microphone makes a palpable difference to your audio recording, allowing you to cut background noise, add reverb and other effects, and even manage equalizer levels to get the audio you desire.
