Please, explain me. What is a difference between mp3/mp3PRO(*.mp3) and Lame MP3 Encoder(*.mp3) files? Thanks.
googled out: mp3pro is meant for low bitrate, and I believe that at 64 kbit/s the quality is better than mp3 at the same bitrate. It uses something called Spectral Band Replication to extrapolate the higher kHz harmonics. This make 64 kbit/s mp3pro sound about equivalent to 112kbit/s mp3.
