MP3 format co-creator Thomson has come out with new software tools for creation and playback of an enhanced version of the old mp3 format. The resulting format, dubbed “mp3HD”, will use lossless compression—making it an exact replica of CD tracks, or at least close enough—for a boost in sound quality and detail.
The resulting mp3HD format will have bitrates in the 500-900kbps range, a whole lot more than the average mp3 file that usually gets ripped at 128kbps. Because of the big bitrate-bump, expect the average 4-minute song’s file size to be around 14-26MB, compared to the average mp3 file that’s at around 4MBs.
Thomson says that the mp3HD files will still be backward-compatible to mp3 players, since the mp3HD file will still contain the regular mp3 data, and the new format will still carry the .mp3 extension. Playing them on an unsupported device will give you none of the benefits, though.
The significantly larger file size might not make much sense to the general public, especially when the detail might not even be that noticeable to the untrained ear. But audiophiles and purists who are into high-end sound will be sure to appreciate the boost in quality.
Utilities and player plug-ins for creating and playing mp3HD files can be downloaded from all4mp3.com or mp3HD.com.
