M4R File Converter

An M4R file is encoded using Advanced Audio Coding (AAC), which provides better sound quality than MP3 at similar bit rates. The file is typically wrapped in an MPEG-4 container, which supports metadata like track name and artist. Because of their structure, M4R files are compatible with most Apple devices but may require conversion for use on other platforms.

M4R files are essentially AAC audio files with a different extension to signify their ringtone purpose. They can be created using iTunes or converted from other audio formats. Interestingly, the M4R format became popular with the release of the iPhone, as Apple aimed to standardize ringtone files for their ecosystem.
