Calibration service for Core Sound's TetraMic

As one result of a NDA signed with Core Sound, I can offer a free calibration service for anyone using their TetraMic on a Linux system. Given the serial number, I will provide a TetraProc configuration based on the impulse response measurements performed by Core Sound on your microphone. Currently this configuration does not use the convolution capabilities of TetraProc, but the results are excellent even without that. The combination of a very well designed microphone with IR-based calibration provides an affordable Ambisonic recording system of really suberb quality.
