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.
About ALAC files
ALAC (Apple Lossless Audio Codec) is a lossless audio format developed by Apple, designed to compress audio files without sacrificing sound quality. It maintains the full fidelity of the original recording while reducing file sizes, making it ideal for music archiving and high-fidelity listening. ALAC is natively supported on Apple devices and iTunes, though it can also be played on other platforms with compatible software. While similar to FLAC in quality, ALAC is optimized for Apple's ecosystem and is a popular choice for users within that environment who want lossless audio without the larger file sizes of uncompressed formats like WAV.
