Lossless audio refers to a type of digital audio compression that preserves the original sound quality of the recording. Unlike lossy formats, which discard some audio data to reduce file size, lossless formats retain all the details, ensuring that the playback is identical to the source. Common lossless audio formats include FLAC, ALAC, and WAV. This high-quality audio is particularly favored by audiophiles and music professionals who seek the best listening experience. Lossless audio files are larger than their lossy counterparts, such as MP3 or AAC, but they provide a richer and more accurate representation of the music.
