[[About me]]
Today I can proudly annouce the arrival of the 3rd version of the digital MEMS microphone array, the DMMA.3 (see [[here|http://homepages.inf.ed.ac.uk/s9903055/datasheet/DMMA3.datasheet.pdf]] for a datasheet).

Based on the USBPAL from [[Rigisystems|http://www.rigisystems.net/index.php/usbpalen.html]] and using eight (8) Analog Devices digital MEMS microphone array [[ADMP441|http://www.analog.com/en/mems-sensors/mems-microphones/admp441/products/product.html]] the DMMA.3 is a circular microphone array with a diameter of 4 cm, ideally to fit onto your pocket size mobile device.

[[Analogue|http://homepages.inf.ed.ac.uk/s9903055/audio/analogue_96k.wav]]

The text for this recordings is:
A: During the day they will also charge the polymer lithium batteries, which will allow the aircraft to fly at night.
B: A second plane is currently under construction.

Experiments will be carried out in the coming months and the results made publicily available soon afterwards.
