DHD Introduces AI-Based Audio Noise Reduction to XD3 IP Core
Posted on Tuesday, March 31, 2026
"The AI-based noise reduction process is much more effective than traditional filter-based tools,” comments Christoph Gottert, DHD international sales manager. "Potential applications include the reduction of background distractions from source content such as sports commentaries or traffic noise from outdoor news reports. Processing intensity can be adjusted quickly and easily at a DHD mixing console or remotely. Three instances, each stereo, can be run in parallel on one XD3 core."
Cores form the heart of every DHD system, processing all the audio as well as connecting control surfaces such as the RX2, compact SX2, desktop DX2, and touchscreen-controlled TX2. DHD cores also perform input/output routing and interfacing with the outside world. IP audio feeds and IP-connected remote device control can be closely integrated. Automated workflows and product virtualisation are also supported. Connectivity options include Audinate Dante, AES67/RAVENNA, AES3/EBU, Gigabit Audio, APC, MADI, and analogue.
Three modules are available in the XD3 range: a controller and IP core, a 12k router extension, plus a DSP extension. These can be operated individually or in redundancy mode as a fully synchronous main and standby pair including seamless switching between the two devices.
The standard XD3 IP core comprises a single DSP processor supporting up to 24 faders and 48 summing busses. Also available is a three-DSP version supporting 64 faders and 96 summing busses, plus a five-DSP version supporting 96 faders and 126 summing busses. Each DSP module uses 40-bit floating-point processing for fader channels, channel processing, fixed processing, and summing operations. Additional routing capacities are provided to allow the use of up to 4, 16 or 24 Gigabit Audio ports respectively. Additional memory for channel delay and program delay is added with each DSP module.
DHD audio GmbH develops and produces digital audio studio equipment and systems for professional applications in broadcast control rooms, DJ-operated radio studios, OB trucks, SNG vans, ingest stations, and edit suites. DHD also produces routing and talkback matrices, audio-over-IP interfaces, and supporting software. DHD devices can be operated directly or under IP networked control. Designed and manufactured in Germany, DHD products are used successfully by broadcasters around the globe.
