What is a AAC file?
AAC, or Advanced Audio Coding, is a widely used audio format known for delivering high-quality sound at relatively low bitrates. Developed as the successor to MP3, it became popular for streaming and digital distribution thanks to its efficient compression algorithms and broad device support.
AAC is the default format for Apple’s iTunes, iOS devices, and YouTube audio. It supports multi-channel audio, a wide frequency range, and features like perceptual noise shaping, making it a favorite for music, podcasts, and even broadcasting.
How to open AAC files
You can open AAC files with most modern media players like VLC, iTunes, Windows Media Player, and QuickTime. They’re also supported on smartphones and tablets without any additional software.

What is a M4R file?
M4R is another extension of the M4A format, used specifically for iPhone ringtones. It contains AAC-encoded audio and is designed to be easily imported into iOS devices via iTunes. In most cases, M4R files are short clips extracted from longer M4A or MP3 songs.
Despite being almost identical to M4A in structure, the M4R extension helps iTunes and iPhones recognize the file as a ringtone rather than music or podcast content.
How to open M4R files
M4R files are used for iPhone ringtones and can be played or transferred using iTunes. On most systems, VLC and QuickTime can also open them directly.
