Love it...
I need a microphone - preferably wireless - for events at a banquet hall. But, we dont have tons of money to throw around. So, through research and a good blog write up, I found this app. No distortion. No delay. The voice does come through, a bit on the canned side but, this was solved with a headset attachment (Bluetooth). Easy transmission through our Apple TV set up. Cheaper and free versions of the microphone and megaphone apps all produced delays, distortion and very canned results.
