Product description: ReSpeaker Mic Array v2.0
ReSpeaker Mic Array v2.0 by Seeed is another more extended version of ReSpeaker Mic Array v1. Based on the XVF-3000 chip. A board with a built-in long-range microphone, capable of detecting voices at a distance of 5 m, even in the presence of background noise.
ReSpeaker Mic Array v2.0 - audio control panel.
Botland is an official distributor of electronics and robotics solutions from Seeedstudio. Hundreds of ready to use devices, components and modules are available from stock or to order. Our team guarantees that all Seeedstudio products presented here are original.
With the ReSpeaker Mic Array v2.0 panel, you can extend your project with a voice interface. It is compatible with Linux, macOS and Windows systems. Array V2.0 has built in similar audio processing algorithms as its predecessor, but with far better code quality.
TheAEC (Acoustic Echo Cancellation)algorithm is a full-duplex solution, which means that the device can playback audio while simultaneously listening to its surroundings. The number of microphones has been reduced from seven to four. Reducing the number of microphones allows for lower board costs. Thanks to the updated algorithms, the final quality of the voice processing has not decreased, but has improved. The new chipset allows for circular or linear electronic design, as well as the ability to change the spacing of the microphones.
Key features of the ReSpeaker Mic Array v2.0 panel
- Voice capture in the far field
- Set of four microphones
- 12 programmable RGB LED indicators
- Voice activity detection
- Direction of sound
- Noise suppression
- Reverberation suppression
- Acoustic echo cancellation
- Supports USB Audio Class 1.0 (UAC 1.0)
