About AAC files
AAC (Advanced Audio Coding) is a highly efficient audio compression format developed by Fraunhofer IIS, AT&T, Dolby, and others. It delivers better sound quality than MP3 at similar bitrates, making it ideal for music streaming, podcasts, and mobile devices. AAC is the default audio format for Apple products (iTunes, iPods, iPhones) and is widely supported across platforms. Its lossy compression reduces file sizes significantly while maintaining excellent audio fidelity, though it's not as universally compatible as MP3.
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.
