About M4A and AAC Formats

M4A (MPEG-4 Audio)

M4A is an audio-only MPEG-4 container commonly used by Apple devices and iTunes. Supports both lossy (AAC) and lossless (ALAC) compression.

AAC (Advanced Audio Coding)

AAC (Advanced Audio Coding) is a lossy format that provides better sound quality than MP3 at similar bit rates. Used by YouTube, Apple, and many streaming services.
