About formats

3G2 (3GPP2 file format) is a multimedia container developed by the 3rd Generation Partnership Project 2 for use on CDMA2000 mobile networks. Built on the ISO base media file format (MPEG-4 Part 12), it stores video encoded with H.263 or MPEG-4 Visual alongside audio in AMR, EVRC, or AAC codecs. The specification was first published in December 2003 to provide a standardized way for CDMA-based phones and networks to handle multimedia messaging and video playback. 3G2 files are engineered for extremely low-bandwidth conditions, achieving playable video quality at bit rates as low as 30-60 kbps. This makes the format especially efficient for mobile video capture on devices with limited processing power and storage. The container supports multiple tracks, timed text for subtitles, and embedded metadata. One significant benefit is near-universal compatibility with CDMA handsets from the mid-2000s era, ensuring reliable playback across a wide range of mobile devices. Though newer formats like MP4 have superseded 3G2 for most purposes, it remains useful for working with legacy mobile content and for situations where minimal file size is the primary concern.
Initial release: December 2003
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.

Frequently Asked Questions

Why convert 3G2 to DVMS?

Some professional or archival systems require DVMS format. Converting 3G2 to DVMS makes your audio usable in those dedicated platforms and tools.

What apps support DVMS playback?

You can play DVMS with SoX and legacy telephony voice messaging tools.

How long does 3G2 to DVMS conversion take?

Our cloud servers handle the processing quickly. Typical 3G2 recordings convert to DVMS in under a minute, though larger files naturally take longer.

Can I convert 3G2 to DVMS on my phone?

The tool works on smartphones and tablets. Open convertio.tools in your mobile browser, upload the 3G2, choose DVMS, and download when done.

Does converting 3G2 to DVMS lose quality?

Quality depends on the bitrate and codec settings you choose. Higher bitrates preserve more detail from the original 3G2 audio track.

Is the conversion private and secure?

Uploaded files are deleted immediately after conversion, and completed DVMS downloads are removed from our servers within 24 hours for full privacy.
