Winamp Mp3Pro Plugin

Combining mp3 with the SBR enhancement technology generates an audio signal with high bandwidth at low bit rates. mp3PRO, the resulting audio format is composed out of two components, the mp3 part for the low frequencies and the SBR or "PRO" part for the high frequencies. Since the "PRO" part requires only a few kbps, the format could be done in a way that it is still compatible with the original mp3 format. This FACT allows existing mp3 players to play mp3PRO files. They simply ignore the PRO part. The only requirement is that they also have to support sampling rates of 16, 22.5 and 24 kHz along with 32, 44.1 and 48 kHz. While all (mp3 standard compliant) software players fulfil this requirement, not all portable and CD/DVD players do. To learn whether your MP3 Player is capable to play mp3PRO files, please check with its manual or manufacturer.
