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.

AMR (Adaptive Multi-Rate) is a compressed audio format optimized for speech, standardized by the European Telecommunications Standards Institute and adopted as a mandatory codec for GSM and 3G mobile networks. The codec dynamically switches between eight bit rates — from 4.75 to 12.2 kbps — depending on network conditions and background noise levels. When link quality drops, the encoder shifts to a lower rate, trading marginal clarity for transmission reliability. This adaptive mechanism is defined by the 3GPP specifications and represents one of the most widely deployed voice codecs globally, used in billions of mobile calls. The primary advantage is compression efficiency: one minute of AMR audio at 12.2 kbps occupies roughly 90 KB, practical for voice memos, voicemail, and MMS on bandwidth-constrained networks. Another benefit is built-in voice activity detection and comfort noise generation, reducing transmission during silence. While AMR is unsuitable for music due to its narrow bandwidth (300-3400 Hz), it excels at delivering intelligible speech under challenging network conditions.

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.
