![]() Hi-res audio is: "Lossless audio that is capable of reproducing the full range of sound from recordings that have been mastered from better than CD quality music sources.".There's no universal standard for high-resolution audio, which is also called hi-res audio or HRA, though The Digital Entertainment Group (in conjunction with the Consumer Electronics Association and The Recording Academy) has published the following formal definition for the term: It was storage and tranmission demands that prompted audio compression in digital forms, and with the cost of storage dropping, and the wider availability of faster mobile and broadband data, this has prompted a move to higher quality music. Whenever any data is lost or removed from a music file during compression, the resolution is negatively impacted. ![]() With lossless compression, all original data from the music file can be restored after it is uncompressed, whereas lossy compression permanently reduces the music file by cutting out some data during the encoding process and makes it much smaller. In order to make a music file smaller, it must go through either lossless or lossy compression. Simply put: they're easier (and cheaper) to distribute to consumers who download or stream. It's no secret that the music industry went from physical formats (like vinyl) to digital formats (like MP3), but most people don't realise sound quality was impacted during that transition due to a demand to make music files smaller. However, other providers have upped their game with many offering higher quality audio.īefore we get into high-resolution audio, let's start by discussing compression. Tidal is one of the most well-known services to offer hi-res audio.
