We decided to improve TwinVQ algorithm with latest MPEG-4 bandwidth extension - Spectral Band Replication (SBR)
MPEG-4 TwinVQ + SBR will be called vqfPro and expected to be CD quality at 32 kb/s!!
VQF, as everybody knows, is a major breakthrough in audio coding technology - with 50% improvements over MP3, and with bandwidth extension it gets additional 30% of bit rate savings.
Special Pre-Post-Echo-Away™ (similar but better than TNS) is used to reduce small problems VQF had with transients.
Additional WMA-Death vbr quality control with multi-pass will bring audio quality to completely new levels.
Expect beta versions soon.
