I have the iRig Pro Duo I/O. I currently use it with my iPhone 14 Pro Max. I connect my saxophone mic to channel 1 and my backing track to channel 2. I then use the iPhone camera to record myself playing. I have the iPhone camera settings to record in stereo but, when I analyze the recording afterwards, the sax is playing out of the left speaker and the backing track out of the right.
Is there a way to get both channels to mix and be stereo? Am I missing something here?
