Avoiding speaker feedback/interference. Help!
I just downloaded the Loopy HD app on my iphone 5 and loving it. I have made a few 9 loop vocal tracks, using a headset and it sounds fine when played from the phone to the headphones. When I plug the iphone into my speakers (3.5mm-3.5mm male cable) to play the tracks with some volume I get incredible feedback above very low volumes. Is there a way of turning the iphone microphone off so there is only output from the device, or any other way of eliminating the feedback? And if more hardware is required to do this, what would you recommend?!
