Yamaha Sound-VQ was software for working with audio encoded using Yamaha's Sound-VQ technology. A VQL file provides locator information that helps the software identify or access related Sound-VQ content.
Because it is a supporting file, a VQL file is normally used together with the Sound-VQ software and its associated audio files. It is not intended to be opened or played as a standalone audio recording.
Open the file with the Yamaha Sound-VQ software that created or uses it. In normal use, the software reads the VQL file automatically when it accesses the related Sound-VQ content.
A VQL file generally cannot be meaningfully opened in a standard audio player or text editor.
A VQL file is locator data, not an audio file, so it cannot be usefully converted to a common audio format. Keep it with the related Sound-VQ files if they are still needed by the Yamaha Sound-VQ software.
