Convert vqf to pvf

What is the difference between .vqf and .pvf?

Description: 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.; The Portable Voice Format (PVF) is a digital audio file format primarily used for storing voice recordings. PVF files are designed to encapsulate voice data at various bit rates, making them suitable for applications where voice clarity and file size are critical, such as voicemail systems, interactive voice response systems, and other telephony applications. Unlike more common audio formats that aim for high fidelity and music playback, PVF focuses on the efficient encoding of speech, optimizing for intelligibility and compact file size.
