- 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 M4A file is an audio file created in the MPEG-4 format, a multimedia container format used to store compressed audio and video data. It contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC).
