You can test the Nero VQF encoder as soon as Nero is installed. You can encode an unlimited number of audio files or pieces of music from CD in the VQF format.
VQF (pronounced Twin VQ) is an audio compression process that was originally invented by NTT (Nippon Telephone & Telegraph). The encoding algorithm on which it is based is different from that used for MP3 or WMA files however. With VQF, a type of standard chip is used to describe sounds with the help of precalculated codebooks. This makes it possible to achieve an attractive sound with the audio files compared with conventional MP3 files that have a lower bit rate. This major advantage is bought at the expense of the very high computing power required for compressing however. Depending on the speed of your PC, audio compression may only take place at real-time speed. Another drawback with the Sound VQ file format is the limited choice of output bit rates compared with the mp3 format. Fewer options are available here at present. Even so, the Sound VQ file format is still an attractive alternative to the conventional MP34 format because of its outstanding packrate. Nero supports both encoding and decoding of VQF files.
The high processing power needed to decompress VQF files means that the maximum possible burning speed will depend on the power of your PC. As a 'rule of thumb' we can say that Pentium systems with a clock speed over 100Mhz should be capable of burning at twice the speed. Computers of Pentium II class and higher should be capable of burning 4 or even 8 times faster. Pentium III or IV PCs can achieve even higher burn speeds.
