About formats

TOD is a high-definition video recording format developed by JVC and introduced in 2007 with the Everio GZ-HD7 camcorder series. Serving as the HD counterpart to the standard-definition MOD format, TOD files contain MPEG-2 transport stream data with H.264/AVC video encoded at resolutions up to 1920x1080 interlaced, paired with AC-3 (Dolby Digital) audio. The format was developed as JVC transitioned its Everio camcorder line from standard definition to high definition, providing a recording format that balanced HD quality with practical file sizes for the hard disk drives and memory cards used as recording media. TOD files share structural similarities with the MPEG-2 transport stream used in broadcast applications, making them compatible with many professional and consumer video tools that handle transport stream content. JVC organized TOD recordings within a directory structure that includes metadata files for clip management, mirroring the approach used for MOD files but tailored to HD content parameters. The format records at bit rates sufficient for high-definition consumer video, typically ranging from 15 to 27 Mbps depending on the recording quality setting selected on the camera. While TOD is specific to JVC products and was eventually superseded by more widely adopted formats like AVCHD, it remains relevant for owners of JVC Everio HD camcorders who need to access, edit, or convert their recorded footage using modern video software.

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.

Frequently Asked Questions

Why convert TOD to VOX?

VOX is built for IVR telephony platforms. Extract audio from proprietary TOD into a purpose-built format.

What uses VOX files?

Systems and apps designed for IVR telephony platforms accept VOX as their native audio format.

Is VOX widely compatible?

VOX is a specialized format. SOX and dedicated tools handle it; mainstream players may not.

Will the quality be adequate?

VOX quality suits its intended purpose. Output depends on the audio quality in your TOD source.

Can I batch convert?

Upload several TOD files and extract VOX audio from each simultaneously.
