[edit] Install nuances on OS X

• Read the comments about Ambdec on this Wiki as most of those apply.
• As the instructions state, you will need Fftw and Libsndfile. When installing Fftw then:

./configure --enable-float

• As the instructions state, you will need to edit the file ~/.tetraprocrc. You need to change two lines. Change "/home/your-login/" to "/Users/zzzzzz/", where zzzzzz is your actual login name (on each of the two lines).

[edit] Calibrating a Native B-Format microphone

An approach to calibrating the elements of a native B-Format microphone is described in detail here.
