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.

NIST SPHERE (SPeech HEader REsources) is a specialized audio file format created by the National Institute of Standards and Technology for speech research, particularly projects funded by DARPA. The format wraps raw audio samples with a structured ASCII header encoding metadata such as sample rate, channel count, encoding type, speaker demographics, and transcription annotations — making it ideal for distributing speech corpora. NIST files typically store uncompressed PCM or mu-law audio at telephone-quality sample rates (8 kHz or 16 kHz), though the container is flexible enough to hold various encodings. A key advantage is the rich self-documenting header that lets researchers embed detailed corpus metadata directly in the file, eliminating sidecar files. SPHERE has also become the de facto standard for major speech databases like TIMIT, Switchboard, and the Fisher corpus, ensuring broad recognition across academic and government labs. The open specification and availability of command-line tools (sphere, h_strip, w_decode) make it straightforward to convert, inspect, and process these files programmatically in speech processing pipelines.
Initial release: 1990

Frequently Asked Questions

Why convert DTS to NIST?

DTS surround audio converted to NIST becomes usable in studio environments and specialized academic audio tools.

What programs can open NIST?

Open NIST with NIST Sphere utilities, SoX, and academic speech processing tools.

What happens to audio quality during conversion?

The converter decodes your DTS and re-encodes it as NIST. Output quality depends on the target format and settings you choose.

Is batch conversion supported?

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

Is the conversion private?

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

What platforms are supported?

Any device with a modern browser — Windows, macOS, Linux, Android, iOS. Convert DTS to NIST from wherever you are.
