What is the difference between .shn and .pvf?

Description: The SHN file format, short for Shorten Compressed Audio File, is a type of compressed audio file developed for efficiently archiving high-quality digital audio. Shorten was one of the early lossless compression methods for audio, meaning it allows the exact original audio data to be reconstructed from the compressed data, without any loss in 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.
