DNR65231-VC1¶

1. Introduction¶

1.1 Product Description¶

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

• The strong noise reduction model employs a deep neural network architecture, effectively handling various stationary and non-stationary noise in complex acoustic environments while maintaining high voice fidelity and achieving maximum noise suppression
• The singing noise reduction model uses a lightweight design to reduce processing latency to 11 milliseconds, 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 multiple application areas including streaming equipment, conference systems, recording devices, and outdoor sports cameras.
