First to bring AAD to market - proven technology that intelligently wakes the audio chain only when sound matters.
Studio‑quality digital capture with flexible I/O to fit any system architecture.
Microamp‑class operation designed for always‑on devices and ultra‑long field life.
Exceptional signal‑to‑noise with a minimal delay profile for clear, natural audio capture.
Access documentation for this line of analog microphones.
Product is EOL and not recommended for new designs
Compact, reliable, and ultra-low-power, delivering superior sound quality and Acoustic Activity Detection with built-in digital output.
When used among mic arrays, TDK microphones act as smart assistants to detect your voice from across the room, clearly and accurately.
High SNR ensures alerts trigger on real events—not background noise—while integrated AAD enables intelligent, low-power monitoring
Designed for outdoors - the high AOP, SNR, and dynamic range of TDK microphones ensure reliable, clear audio in any environment.
New cutting-edge application area enabled by smart sound microphones. With mics an audio interferace becomes possible
