Purpose

Denoise removes background noise from a signal using an NVIDIA noise-removal model. It is built for cleaning up dialogue, voice capture, and live input where steady noise sits under the wanted sound.

Use

Insert it inline on a noisy source. Wire audio into in and out onward. Set Modelpath to the noise-removal model file, then use Strength and Intensity to balance noise reduction against keeping the voice natural.

Inputs and outputs

• Input 0: in accepts mono or stereo PCM. It is required.
• Output 0: out emits the same shape as the input.

Controls

• Strength: how aggressively noise is removed.
• Intensity: blend between the original and the cleaned signal, for dialing back over-processing.
• Modelpath: path to the noise-removal model file.

Notes

• Denoise runs on an NVIDIA GPU and needs the NVIDIA Audio Effects runtime and a model file installed on the machine. If the runtime or model is missing, the node passes audio through.
• Detection works on a single channel and is applied across the output, so the cleaned result is centered.
• Push Strength only as far as the voice still sounds natural; back off with Intensity if it sounds processed.
