About formats

M2V is a file format containing MPEG-2 video elementary streams without an encapsulating container or associated audio data. Standardized as part of ISO/IEC 13818-2 (also known as ITU-T H.262) by the Moving Picture Experts Group in 1995, M2V stores raw compressed video exactly as it would appear within an MPEG-2 program or transport stream, but stripped of all multiplexing overhead. This makes M2V files primarily useful in professional authoring workflows, particularly DVD production, where video and audio streams are prepared and encoded separately before being muxed together into the final container format. M2V streams support both interlaced and progressive scan modes at resolutions ranging from standard definition up to 1920x1080 HD, with bit rates typically ranging from 2 to 15 Mbps for consumer content and up to 80 Mbps in professional applications. The use of both intra-coded frames and predictive frames provides an effective balance between compression efficiency and random access capability. Because M2V contains only video with no audio or synchronization information, it requires pairing with a separate audio file for complete playback. DVD authoring software commonly expects M2V input alongside AC3 or LPCM audio files, making this format an essential intermediate step in professional disc mastering and broadcast preparation workflows.
Initial release: July 1995
VOX is a headerless audio format built around Dialogic ADPCM encoding, widely adopted in telephony, interactive voice response (IVR) systems, and voice mail platforms since the 1980s. Each audio sample is compressed into 4 bits using an algorithm developed by Oki Electric and implemented in hardware on Dialogic Corporation's telephony interface cards. VOX files typically use a sampling rate of 6000 or 8000 Hz, producing extremely compact recordings optimized for speech intelligibility rather than musical fidelity. Because the format carries no header, playback software must know the sample rate and encoding parameters in advance — a trade-off that reduces overhead but demands careful file management. The primary advantage of VOX is storage efficiency: a one-minute voice recording at 8 kHz occupies roughly 240 KB, making it practical for systems storing thousands of prompts. Dialogic ADPCM conforms to the ITU-T G.726 standard, ensuring interoperability across telephony equipment from different vendors. Even as modern call centers migrate to IP-based systems with codecs like Opus, vast libraries of VOX recordings persist in legacy IVR deployments and compliance archives worldwide.
Initial release: 1983

Frequently Asked Questions

Why should I convert M2V to VOX?

Converting M2V to VOX extracts whatever audio data accompanies the video stream, producing a standalone audio file for any player.

Which applications support VOX?

Telephony IVR systems, Dialogic hardware, and VoIP platforms process Dialogic VOX audio.

Does it work on phones and tablets?

Yes. The converter runs in any modern mobile browser on iOS and Android devices, with the same functionality as desktop.

What happens to my uploaded files?

Uploaded M2V files are deleted from our servers immediately after processing. Converted VOX files are auto-removed within 24 hours.

Can I convert several files at once?

Yes. Upload multiple M2V files and extract VOX audio from each one in a single batch operation — fast and convenient.
