Lossless audio refers to a type of digital audio compression that preserves the original quality of sound without any loss of data. Formats like FLAC and ALAC allow music enthusiasts to enjoy high-fidelity audio while saving storage space compared to uncompressed formats. Unlike lossy formats such as MP3, which discard some audio information to reduce file size, lossless audio retains every detail of the original recording. This makes it a preferred choice for audiophiles and professionals who require the best sound quality for music production and listening experiences.
