Function and characteristic

Main Features:

Multi-Scenario Drag-and-Drop Architecture

An open platform that auto-loads required modules by scenario, allowing fast drag-and-drop DSP configuration without manual wiring.

Auto-Snap Programming Connections

Modules automatically snap into correct nodes when dragged, enabling quick programming without deleting or reconnecting signal lines.

Advanced Audio Processing Technologies

Built-in AEC, adaptive filters, crossovers, and FIR algorithms deliver high-quality, stable audio performance across diverse application scenarios. 

DSP Module Color Indicators

Two color states clearly show module signal on/off status, simplifying troubleshooting and improving system visibility. 

Multi-Device Operation & Scenario Switching

Supports multiple device models with cross-device copy/paste and built-in DSP modes for meetings, hybrid conferencing, and BGM.
