About formats

MTS is a file extension associated with the AVCHD recording format, jointly developed by Sony and Panasonic for high-definition consumer camcorders. Files with the MTS extension contain MPEG-2 transport stream data carrying H.264/AVC video at resolutions up to 1920x1080, paired with Dolby Digital (AC-3) or LPCM audio. The MTS designation is used when AVCHD content is accessed directly from the recording media, as opposed to M2TS files which typically refer to the same transport stream format in Blu-ray disc contexts. Consumer and semi-professional camcorders from Sony, Panasonic, Canon, and other manufacturers write MTS files into a structured directory hierarchy on memory cards or internal storage, accompanied by index and playlist files that organize clips for in-camera playback. The transport stream packaging includes timing information critical for maintaining audio-video synchronization and supports features like random access points for efficient seeking. MTS recordings preserve the full quality captured by the camera sensor, making them suitable as source material for editing workflows. The use of H.264 compression provides an effective balance between video quality and file size, enabling extended recording times on commonly available SD and SDHC memory cards. MTS files are recognized by all major video editing applications and can be imported directly into editing timelines, though some workflows benefit from transcoding to editing-optimized formats for smoother real-time performance.

CVU is an unsigned variant of the CVS telephony audio format, differing in how delta-encoded values are represented in the binary stream. While CVS stores slope delta values as signed quantities, CVU treats them as unsigned, shifting the numerical interpretation of each sample. Both share the underlying CVSD modulation technique — 1-bit adaptive delta coding where step size varies according to recent output bit patterns — operating at comparable rates, typically 16 kbps for narrowband voice at 8 kHz. The signed-versus-unsigned distinction matters at the decoder, where correct interpretation determines proper waveform reconstruction. CVU files appear in telephony and embedded communication contexts where hardware adopted the unsigned convention. A practical advantage is straightforward interfacing with systems using unsigned arithmetic natively, avoiding sign extension in decoders. Like its signed counterpart, CVU achieves extreme bandwidth efficiency, compressing voice into compact bitstreams for constrained links. SoX supports CVU, providing a reliable path for converting these niche telephony recordings into modern formats for analysis or archival.

Frequently Asked Questions

Why convert MTS to CVU?

CVU provides CVU encoding for telephony platforms. Converting extracts compatible audio from your MTS camcorder recordings.

What software handles CVU?

Specialized audio tools, SoX, and format-specific applications handle CVU files for playback and processing.

Is CVU widely supported?

CVU serves specific use cases. For general audio needs, MP3, WAV, or FLAC are more broadly compatible.

Can I adjust encoding settings?

Yes — configure sample rate and encoding parameters before converting to match your target system requirements.

Is batch conversion available?

Upload multiple MTS files and extract CVU audio from each simultaneously in one session.
