mp3PRO

An enhanced MP3 format from Coding Technologies that reduced an MP3 file to half its size while retaining the same sound quality. Thomson Multimedia, which later became Technicolor SA, licensed the technology in 2001. However, mp3PRO was never widely used because it was not compatible with MP3 players that did not support the format. See aacPlus and MP3.


Spectral Band Replication (SBR)
mp3PRO used Spectral Band Replication (SBR) to cut the sampling rate in half and encode the missing high frequencies at 1.5 Kbps, which are stored in the auxiliary data fields. The decoder restores the high frequencies from the SBR data.
