Use your iPhone/iPad as a microphone and output sound to headphones or speakers. You can also use it to record audio instead of playing sound. The app comes with four built-in effects. Stereo input is available on compatible devices only. The microphone on the iPhone is positioned vertically, so by using it in landscape orientation, you can experience a greater sense of stereo sound. Please note that this app was created just for my personal use, and I cannot guarantee its performance on devices I do not own.
