What is FLAC?

FLAC (Free Lossless Audio Codec) provides lossless compression of digital audio without any quality loss, reducing file size by 50-60%.

What is AIFF?

Audio Interchange File Format (AIFF) is Apple's uncompressed audio format, offering CD-quality sound for professional audio production.
