DNR65231_VC1

Single-Channel Ultra-Low Latency AI Deep Noise Reduction Processor with USB and I2S Interface

DNR65231_VC1 Block Diagram

DNR65231 is a high-performance AI deep noise reduction product based on XMOS processor architecture, designed to provide audio equipment manufacturers with exceptional audio processing capabilities. The product integrates two independently optimized AI noise reduction models.

  • The strong noise reduction model employs a deep neural network architecture, capable of effectively handling various stationary and non-stationary noises in complex acoustic environments, achieving maximum noise suppression while ensuring high fidelity voice restoration
  • The vocal noise reduction model reduces processing latency to 11 milliseconds through lightweight design, effectively suppressing background noise while fully preserving vocal characteristics.
  • The product supports I2S audio input with output to USB, and also supports USB audio output to I2S, widely applicable to streaming equipment, conferencing systems, recording devices, outdoor action cameras, and many other applications.
