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?

What You Need to Use Amazon Music HD There are a few requirements for listening to Amazon Music HD. You need an Amazon account, but you don’t have to have a Prime membership.Then, you need to download the desktop app to get HD features, which the web doesn't support.Amazon recommends a reliable internet connection of 1.5 to 2 Mbps for HD streaming and 5 to 10 Mbps for Ultra HD streaming, which is typically available in LTE signals.For data usage concerns, HD audio typically consumes up to 5.5 MB of data per minute, and Ultra HD audio up to 12 MB of data per minute (when listening at the highest sample rates). Compatible devices: Alexa-enabled Echo devices (2nd generation and later), Fire TVs, and Fire Tablets all support HD quality audio. The Echo Studio supports Ultra HD quality audio.Most iPhones and iPads released since 2014 (devices running on iOS 11, or later) can support HD/Ultra HD (up to 24-bit, 48kHz) without any additional equipment.

Apple AirPlay supports HD quality playback.Most Android devices released since 2014 can support HD/Ultra HD playback (up to 48kHz).
