Convert M4R to AIFC

The M4R file extension stands for MPEG-4 Ringtone and is primarily used for creating custom ringtones for Apple devices, particularly iPhones. This format, a variant of the standard MPEG-4 Audio (M4A), emerged alongside the introduction of the iPhone in 2007. M4R files utilize Advanced Audio Coding (AAC) for compression, ensuring high-quality sound in a compact file size. Their use is strictly tied to Apple's ecosystem, allowing users to personalize their device's ringtones through the iTunes platform. M4R's history is closely linked to the evolution of mobile technology and the personalization trend in smartphone usage.

The AIFC file extension stands for Compressed Audio Interchange File Format, which is a variant of the AIFF (Audio Interchange File Format) used for storing audio data. Developed by Apple in the late 1980s, AIFC files incorporate compression to reduce file size while maintaining audio quality, making them suitable for professional audio applications. They support various compression codecs, such as ADPCM and MPEG-4, and are commonly used in digital audio workstations and multimedia software. AIFC files ensure high fidelity and compatibility across different platforms, enhancing audio storage and distribution efficiency.
