AMT 3447
Ultra-low-power Sound Processor with 16 APUs
The AMT3447 is an ultra-low-power, high-performance microcontroller engineered for next-generation audio processing. Featuring 16 independent Audio Processing Units (APUs), this cutting-edge device delivers unparalleled flexibility in sound shaping and enhancement. Each APU operates as a fully programmable digital filter—empowering developers to fine-tune the audio recording path with precision control. Whether you’re building advanced voice activation systems, smart acoustic interfaces, or high-fidelity audio capture technologies, the AMT3447 brings professional-grade DSP capabilities into a compact, energy-efficient footprint.
