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.

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.
