Higher order ambisonics till now has been based on synthesis and manipulation. There have been very few live recordings and very few microphones which can record in second order.
So there is a lot of excitement for the i arrival of a compact 2nd order microphone which can be directly plugged into an eight channel recorder.
Outputs are to two 12pin DIN connectors, one carrying channels 1-4 and the other carrying channels 5-8. A provide very flexible Mogami cables to connect these to the recorder.
The microphone will be accurately calibrated, with filtermatrix files to produce output signals as 2nd order B format or SPS format with much higher positional resolution than a four channel first order microphone.
The microphone is priced at 1800 USD. It will come with an experimental shockmount, and two 1.5 meter cables, DIN 12 F one side four XLR 3 M on the other side. Longer lengths can be ordered.
We now have a reliable calibration system for the microphone so we have begun to take orders.
Want a listen ? here is an early recording at a 3rd Century BC theater in Orissa. Recorded from a distance of 10 meters with Brahma-8 ser no 001.
Both stereo and 2nd order Ambisonic (8-channel) versions.
