Compressing files degrades audio quality, but it also makes the file smaller, so it’s not taking up a lot of storage space, and it’s quick to download. Tidal, which offers a hi-fi plan that uses the FLAC file format, is Amazon Music HD’s direct competitor. Amazon Music HD uses lossless FLAC files, which preserve audio quality. Its library includes HD audio (CD-quality; bit depth of 16 bits and a 44.1kHz sample rate) and Ultra HD audio (24-bit with sample rates that range from 44.1kHz up to 192kHz). Whether you can tell the difference depends on your ears and your audio equipment. Need help understanding these specs? Learn about common audio terms, including sample rate (Khz), bit-depth, and bit-rate. How Is Amazon Music HD Different from Prime Music and Amazon Music Unlimited?
