A VQF file, standing for TwinVQ (Vector Quantized) Audio File, is a compressed audio format developed by NTT (Nippon Telegraph and Telephone Corporation) in the late 1990s. It was designed to offer higher compression rates compared to the more commonly used MP3 format, aiming to produce smaller file sizes while retaining a similar audio quality.
An OPUS file is an audio file created in the Opus format (also called "Ogg Opus"), a lossy audio format developed for Internet streaming. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s.
