The CrispMic® is a highly directional, USB plug-and-play array microphone that provides crisp, clear, noise-reduced speech at one meter away. Developed by Li Creative Technologies, Inc., CrispMic^TM is designed for optimal use with speech recognition software, Skype®, conference call software, and VoIP software. Advanced acoustic beam forming and noise reduction on its multiple microphones allow the user to capture clean speech signals regardless of their noisy background environment - at home, at work, or outdoors.

The CrispMic® is portable: it can be mounted on a laptop or flat screen and includes a stand for easy table-top installation. It also has a built-in DSP processor, so the device does not need to share CPU power with a computer or laptop.

The CrispMic® has two modes: (1) Light ON: optimized for speech recognition; (2) Light OFF: optimized for speech communications and VoIP apps, especially in noisy environments.

With CrispMic® you can untether yourself from your headset or close-talking microphone yet still obtain superior microphone performance, all at a price you can afford.

Please refer to the Datasheet for technical and performance specifications.
