NTT TwinVQ encoder

TwinVQ Player TwinVQ is an audio encoding technology developed at NTT (Nippon Telephone and Telegraph). It uses an unique technology called Vector Quantization (VQ) for encoding.

The format using the TwinVQ technology is called VQF. There are several limitations in this format: 2 channels at most, no VBR, very slow encoding, little support, no public specifications or open source implementation. It can pretty safely be considered dead these days.

TwinVQ, on the other hand, is still alive as part of the MPEG4 audio standard, being used for very small bitrates (8-16kbps).

A mirror of the NTT TwinVQ page is available here.

TwinVQ Encoder I am also mirroring Thor's page from dalnetvqf, featuring VQF plugins for Winamp. Thanks to Thor for providing these files.
