About formats

3GP is a multimedia container format defined by the 3rd Generation Partnership Project as the standard media format for 3G mobile services. Based on the ISO base media file format (MPEG-4 Part 12), it was designed to reduce storage and bandwidth requirements so that mobile phones with limited capabilities could efficiently capture, store, and play video content. The format typically uses H.263 or H.264 video codecs paired with AMR-NB, AMR-WB, or AAC audio. 3GP was instrumental in bringing multimedia to mobile devices during the early smartphone era, when network speeds and device hardware imposed tight constraints on file sizes. The streamlined container strips away overhead found in full MP4 files, resulting in significantly smaller files that stream reliably over slow 3G connections. 3GP supports both GSM and UMTS network protocols and includes provisions for timed text and still images within the container. Broad adoption by major handset manufacturers ensured that practically every 3G-capable phone could handle 3GP media natively. Although modern mobile devices now favor MP4 and other advanced formats, 3GP files are still encountered in archives of older mobile recordings and in regions where bandwidth-efficient video delivery remains important.

PVF (Portable Voice Format) is a simple audio file format designed for voice message storage in Linux-based telephony systems, most notably ISDN4Linux and its vbox voicemail application. The format emerged from the European ISDN ecosystem of the late 1990s, when Linux servers increasingly handled PBX and answering machine duties over digital phone lines. PVF files store raw signed 16-bit PCM samples at 8000 Hz mono, preceded by a minimal plain-text header specifying data format and byte ordering. This deliberate simplicity is one of the format's primary strengths — with no compression and a human-readable header, PVF files are trivially easy to parse, pipe, and manipulate using standard Unix tools. The 8 kHz rate matches the Nyquist requirement for telephone-bandwidth speech (300-3400 Hz), making PVF a natural intermediate format for voice processing pipelines. Another advantage is cross-architecture portability: the explicit byte-order declaration means PVF files move between big-endian and little-endian systems without ambiguity. The SoX audio toolkit provides native PVF read/write support, enabling straightforward conversion to modern formats.
