GarageBand iPhone exports M4A, not MP3

Unlike GarageBand for Mac, the iOS version only exports as M4A. This format works in Apple's ecosystem but requires conversion for most music distribution and sharing platforms. Converting to MP3 at 192kbps or higher preserves audio quality while ensuring universal compatibility.
