Both keep file sizes reasonable but, as the name implies, deliver hi-res audio in a lossless format. Less commonly, you’ll see ALAC, or the Apple Lossless Audio Codec. The most common format you’ll see when shopping for hi-res music is FLAC, or the Free Lossless Audio Codec. There are more possible hi-res audio formats than we’re going to mention here, especially when you get into streaming, but we’ll look at the most common. While lossless audio definitely has a place in hi-res audio, lossless audio itself doesn’t qualify as hi-res audio, as CD audio itself is lossless. MP3 is the best-known type of lossy audio compression but is declining in popularity in favor of better-sounding formats. This is compared to lossy compression, which reduces audio fidelity to shrink file sizes. Lossless audio refers to the type of file compression (or lack thereof) used to keep the file size or stream bitrates lower.
