Question: what are lossless audio formats?
Answer: A lossless file, the FLAC (Free Lossless Audio Codec) is compressed to nearly half the size of an uncompressed WAV or AIFF of equivalent sample rate, but there should be no “loss” in terms of how it sounds. ... Other lossless audio file formats include ALAC (Apple Lossless) and WMA Lossless (Windows Media Audio).
