The higher the bitrate, the more information it transfers and the better it's going to sound (assuming you have the necessary components to properly play it).
The lower the bitrate, the less information and the worse a digital audio file is going to sound. In a nutshell, the bitrate of an audio file is the amount of data transferred per second. The bitrate of a digital audio file is the primary metric we use to determine audio quality. And not every lossless streaming service supports them. The catch is that most lossless streaming services don't have a huge catalog of these ultra high-resolution audio tracks. For example, Tidal gives its HiFi subscribers the option of listening to Master Quality Authenticated (MQA) certified tracks (up to 24bit/96kHz), while Amazon Music HD gives its subscribers the ability to listen to "Ultra HD" (up to 24-bit/192kHz).
In popular use "lossless" means the same quality as a CD (16-bit/44.1 kHz), but there are a number of lossless streaming services that offer even higher-quality digital audio files. Lossless just means that no detail has been destroyed in the compression process the quality of the lossless file therefore depends on the original source that's being compressed. The average size of lossless compressed audio file, such as FLAC or ALAC (Apple Lossless), is now a little more than 1/2 the size of its original recording.Īpple Is there anything better than lossless? For context, the average size of a compressed audio file, like a MP3 or a AAC, is about 1/4 the size of its original recording. "Lossless" doesn't mean uncompressed, but rather it refers to a type of compressed digital audio file that uses advantaged data compression algorithms so that the audio track doesn't "lose" any detail in the compression process. This squishing process is "lossy" the end result is missing detail that the previous, un-squished version had, specifically at the low and high ends, so that it doesn't sound nearly as good. These are files that have pointedly squished so they take up less storage space on your smartphone or digital music player.
