Set the overall output DCA audio bitrate.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

sou

SOU is a raw audio format designation that functions as an alias for unsigned 8-bit PCM data (u8) in the SoX audio processing framework. Files with the .sou extension contain headerless, uncompressed audio samples stored as unsigned 8-bit integers — each byte represents a single amplitude value from 0 to 255, with 128 as the silence midpoint. Because there is no header, playback parameters such as sample rate and channel count must be specified externally. The default assumption is typically mono at 8000 Hz, though the data can represent any rate the recording hardware supported. The u8 encoding that SOU aliases is one of the simplest possible digital audio representations, predating structured audio containers like WAV and AIFF. Raw unsigned PCM was commonly produced by early sound cards and digitizers in the late 1980s and early 1990s, when storage constraints and limited processing power made headerless formats a practical choice. One advantage is absolute simplicity: SOU files can be read by any program capable of basic file I/O, with no parsing of container structures or metadata decoding required — useful for embedded systems, hardware diagnostics, and educational contexts where audio fundamentals are being explored. The format's minimal overhead also means that conversion to any modern container is lossless and instantaneous, since the raw PCM samples can be wrapped in a WAV or AIFF header without any transcoding.

dts

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.

Frequently Asked Questions

What is the benefit of converting SOU to DTS?

Since SOU has bare PCM data requiring manual configuration to play back, switching to DTS provides cinema-grade multi-channel audio.

What programs can play DTS?

You can open DTS with VLC, PotPlayer, home theater receivers, and Blu-ray players.

Will I lose audio quality converting SOU to DTS?

SOU stores voice at very low quality. Moving to DTS makes the audio playable everywhere — quality stays consistent with the source.

Does this converter work on mobile devices?

Absolutely. Since conversion happens in the browser, any device with internet access and a modern browser will work.

How long does SOU to DTS conversion take?

Most conversions finish within seconds. Processing time depends on recording length, but the cloud-based engine handles it quickly.

What if my SOU recording is very long?

The converter handles recordings of various lengths. For very large or numerous files, premium plans provide extended capacity.
