Recording with TetraMic

Using the TetraMic

The TetraMic is a tetrahedral soundfield microphone made by Core Sound, and I have described it in detail elsewhere on this site.  The microphone does not include electronics to process the output from the capsules (known as A-format) into the B-format that is used for storage and processing, so this has to be done by computer, either live while recording or later in post-processing.

When I first received the TetraMic (in 2007), I continued to use the same equipment for recording as I had been doing with my native B-format setup; I merely added the conversion from A- to B-format to my workflow in place of the alignment procedures that were necessary previously (the conversion uses a customised parameter file supplied by Core Sound, which makes all the necessary corrections for the particular set of capsules).

I have now (in 2011) started using a Tascam DR-680 recorder, which is quicker and easier to set up.  I will add illustrations and further details here at some future time.
