About CAF files
The CAF (Core Audio Format) is an audio file format developed by Apple for professional audio applications. It supports high-quality audio with flexible compression options and can store multiple tracks, metadata, and effects. CAF is widely used in Apple's audio production tools like Logic Pro and GarageBand due to its reliability and large file size support. While not as common as MP3 or WAV, it is valued for advanced audio editing and recording needs.
About M4A files
M4A (MPEG-4 Audio) is a high-quality audio format developed by Apple, based on the AAC (Advanced Audio Coding) standard. It offers better sound compression than MP3 while maintaining excellent audio quality, making it ideal for music and podcasts. M4A files are often used in iTunes and Apple devices, supporting lossy compression with smaller file sizes than MP3 at similar quality levels. Though less universal than MP3, it is widely supported on modern devices and media players.
