MP3

MP3

The MP3 file format is a widely used digital audio encoding format that compresses audio data with minimal loss of quality, making it ideal for storing and sharing music efficiently. It is supported by a vast range of media players, such as VLC, Windows Media Player, and iTunes, as well as editing tools like Audacity and Adobe Audition. The format uses a lossy compression algorithm based on perceptual coding, which removes inaudible frequencies, and supports metadata like ID3 tags for storing song information, album art, and more.

FLAC

Free Lossless Audio Codec

FLAC (Free Lossless Audio Codec) is an open-source audio format designed for lossless compression, preserving original audio quality while reducing file size. It is widely supported by media players like VLC, Foobar2000, and streaming platforms such as Tidal, and can be created or converted using tools like Audacity or XLD. FLAC files use metadata tagging (e.g., ID3, Vorbis comments) and support high-resolution audio, multichannel audio, and optional error-checking for data integrity.
