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 AC3 files
AC3 (Audio Coding 3), also known as Dolby Digital, is a multi-channel audio compression format developed by Dolby Laboratories. It efficiently reduces file size while maintaining high sound quality, supporting up to 6 channels (5.1 surround sound). AC3 is widely used in DVDs, Blu-rays, digital TV broadcasts, and home theaters. Though a lossy format, it delivers excellent audio performance for entertainment purposes, though not suitable for professional audio mastering due to its compression.
