What Is Lossless Audio?
Most audio compression techniques lose some amount of data contained in the original source file. This occurs when music is compressed into an MP3 format in order to discard all the sounds a machine thinks cannot be audibly perceived by the human ear. This reduces the amount of storage needed to hold entire albums.
The issue with this form of compression is that bits of the discarded audio can be perceived and listeners are left with the feeling that they’re listening to lower quality music. To use lossless audio, you will require a player that supports it.
What Is HD Music?
High-Definition audio, also referred to as HD audio is a term for audio files with greater than 44.1kHz sample rate or higher than 16-bit audio bit depth. Unlike standard streaming music tracks, HD music uses lossless compression (as mentioned earlier in this article) whereby more information from the original recording is preserved, in order to be considered HD, music tracks need to be lossless.
