About formats

DTS (Digital Theater Systems) is a multi-channel audio codec originally engineered for cinema sound, now a staple of home theater and Blu-ray releases. Conceived by DTS, Inc. and first showcased theatrically alongside the 1993 film Jurassic Park, the technology delivers up to 5.1 discrete channels of surround sound at bit rates typically between 768 kbps and 1.5 Mbps. Unlike competing codecs that lean on aggressive psychoacoustic modeling, DTS allocates a higher data budget to each channel, preserving finer spatial detail and low-level dynamics. The format encodes audio using sub-band ADPCM combined with vector quantization, producing a perceptibly rich sound field. Its extended variant, DTS-HD Master Audio, adds a lossless extension layer for bit-for-bit accuracy up to 24-bit/192 kHz. Key strengths include broad hardware adoption across AV receivers, gaming consoles, and automotive infotainment systems, along with robust error concealment that masks minor disc or stream glitches. For anyone working with surround-sound content intended for physical media or high-end streaming, DTS provides a proven pathway from studio mix to living room.

CVSD (Continuously Variable Slope Delta modulation) is a voice digitization method standardized for military and telephony use by NATO and the CCITT during the 1970s. It encodes differences between consecutive samples as a single bit — 1 if the current sample exceeds the prediction, 0 otherwise — while a syllabic companding filter adjusts step size by monitoring runs of identical bits. Operating at 16 to 64 kbps, CVSD balances voice intelligibility against bandwidth, making it the encoding of choice for secure military links and tactical radio systems. The bitstream can be decoded with straightforward hardware, originally built into dedicated integrated circuits. One advantage is implementation simplicity — encoders and decoders need minimal resources, enabling real-time processing on low-power embedded hardware. Robustness under noisy conditions is another strength, as single-bit errors affect only local samples rather than corrupting entire frames. SoX provides software encoding and decoding support, letting modern systems work with legacy CVSD recordings from military archives and vintage telecommunications infrastructure.

Frequently Asked Questions

Why convert DTS to CVSD?

DTS surround audio needs re-encoding for voice systems. Converting to CVSD makes it ready for telephony or VoIP use.

What programs can open CVSD?

Open CVSD with SoX and telecommunications software supporting CVSD encoding.

Is there quality loss converting to CVSD?

CVSD is a specialized format with its own encoding constraints. Quality depends on CVSD capabilities and the settings you choose.

Is batch conversion supported?

Absolutely. Drop multiple DTS files into the converter and they will all be processed to CVSD together in one operation.

Is the conversion private?

Yes — your DTS is removed from our servers right after processing. CVSD output files are automatically deleted within 24 hours.

Is the conversion fast?

Speed depends on the DTS file size, but most audio conversions to CVSD complete within seconds thanks to server-side processing power.
