Convert AIFF to M4R

Understanding AIFF and M4R file formats

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple, widely used for storing high-quality audio data. It is commonly used in professional audio and music production due to its lossless nature and excellent sound fidelity.

M4R is a specialized audio format based on the MPEG-4 Part 14 standard, primarily used for iPhone ringtones. M4R files are essentially AAC-encoded audio files with a .m4r extension, optimized for use on Apple devices.

Why convert AIFF to M4R?

Converting AIFF to M4R is necessary when you want to use a high-quality audio clip as a custom ringtone on an iPhone. Since iPhones only recognize ringtones in the M4R format, converting your AIFF files ensures compatibility and allows you to personalize your device.
