The WT1388 is an AI noise reduction audio processing chip independently developed by Nanjing Indigo Microelectronics. The WT1388 integrates a neural network acceleration engine and a high-performance audio processing unit, enabling it to suppress background noise in real-time under various complex acoustic environments, significantly enhancing speech clarity and intelligibility. The WT1388 can effectively handle multiple types of non-stationary noise such as wind noise, motor noise, and crowd noise, providing stable, low-latency noise reduction performance with low power consumption. It is suitable for application scenarios such as two-way radios, wireless headsets, industrial, and outdoor terminals. ■ Audio Interface Specifications: ▪ 100dB SNR (A-weighted) ▪ Supports analog differential input/output ▪ ADC/DAC sampling rate: 8kHz ■ Operating Voltage: Digital 3.3V, Analog 3.3V ■ QFN40L Package: 5.00mm × 5.00mm × 0.75mm ■ Function List: ▪ AI noise reduction based on neural network training Application Scenarios: Two-way Radios, Wireless Headsets |
