AISonic™ SmartMics are low-power, intelligent microphones from Knowles that are adaptable across various form factors in mobile devices, true wireless stereo (TWS) earbuds, and IoT applications. They enhance audio processing and understanding while maintaining a compact size. By handling data processing at the edge, these SmartMics offer wake-on-voice capabilities with reduced power consumption and increased privacy, all without compromising performance.
