What is the difference between .pvf and .mp3?

Description: 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.; An MP3 file is an audio file saved in a compressed audio format developed by the Moving Picture Experts Group (MPEG) that uses "Layer 3" audio compression. It is commonly used to store music and audiobooks with near-CD quality sound (stereo, 16-bit) and roughly 1/10 the size of a .WAV or .AIF file.
