VQF is a file extension that supports the TwinVQ audio format. NNT Labs developed it using the TD weighted enclosed vector quantization to create small data files. However, this product is marketed by Yamaha as SoundVQ. You can encode it in 80, 128, 96, 192, and 160 kbps bitrates. This extension is compatible with various operating systems, including Windows, Linux, Android, iOS, and macOS. You can use different programs to open these files, from VideoLAN VLC, File Viewer Plus, and Nero 2018 to Nullsoft Winamp. In addition, it allows you to convert files into .vqf format, making it easier to play different audio files.
