I've not used that product.

You didn't say how the microphones are oriented / arranged.  You also didn't
say if you intend to do simple summation beamforming or also intend to do
beam steering.  With simple summation beamforming (no delays inserted in the
element (microphone) channels) you will still need to align the delays if
the ADC is sequential across the channels.

You might try alt.sci.physics.acoustics with your question.

One parameter to look out for, is how well the sampling in the different 
channels are synced. The ideal array sampling system would consist of 
8 ADCs in parallel that sample in the exact same moment with neglectable
"sample and hold" times. 

You should try to find a data sheet for this thing, and see how the sampling 
is done, and decide whether it suits your needs.

I was looking for eight microphone inputs and something not too expensive.
I wondered (even though the application is for music) if this would fit the bill

It comes with software - maybe I could create 8 .wav files with this kit and process
off-line.I don't need real-time processing at present.
Anybody used it for anything or got any other ideas?


Thanks
