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.

rm

RM (RealMedia) is a proprietary multimedia container format developed by RealNetworks beginning in 1997. The format was designed specifically for streaming media delivery over the internet, packaging RealVideo and RealAudio codecs into a container optimized for low-bandwidth playback. RM became one of the dominant streaming formats in the late 1990s and early 2000s, when RealPlayer was among the most widely installed media applications and RealNetworks pioneered the concept of buffered streaming video before broadband became widespread. The format uses constant bit rate encoding and a proprietary container structure that supports forward error correction, allowing reasonably smooth playback even over unreliable dial-up connections. RM files can contain multiple streams at different bit rates, enabling SureStream technology that adapts playback quality to available bandwidth in real time. The container supports metadata for title, author, and copyright information, and RealNetworks developed the RTSP and PNA streaming protocols alongside the format for efficient network delivery. Compression in RM was considered impressive for its era, delivering watchable video at bit rates as low as 20-30 kbps when competing approaches struggled. While RealMedia has been largely replaced by modern streaming technologies, RM files remain in archives from the early internet era, including news organizations, educational institutions, and media libraries that adopted RealMedia during its peak popularity.

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.
