Recording Ambisonic A-Format audio is a fairly specialised task which should be undertaken by someone with experience in that particular field. You need a 4-channel field recorder with identical gain and phase structures across all 4 channels in order to record the 4-channel 1st order A Format signal. There are not many recording devices that are suitable ...

You will need a set of plugins/tools that allow you to up-mix mono and stereo files to B-Format. This will usually involve orientation of the incoming signal around three planes (pitch, roll, yaw). Were you to be using Reaper, the Ambisonic Toolkit is freely available for this purpose. The workflow usually involves laying up your mono and stereo effects ...

An omnidirectional capsule is a pressure receiver whereas all directional capsules are pressure gradient receivers. That means that you would need to drill the right amount of holes/sound paths behind the membrane to get a proper cardioid capsule. Going the other way is much more realistic (namely closing the sound paths to the back of the membrane). You ...

It you look at a classic microphone, like the SM-58, you will realize that the capsule itself is somewhat omni. What creates the directivity are tiny accoustic pathways (tunnels? Not sure how to call them in english) that cause the sound to enter the back of the capsule with a slight delay, causing phase cancellation in the back. I have honestly no idea ...

Hi all, I was following this thread. I love that some of you are as interested as I am in using ambisonics with the visual medium. At this point, my master's thesis may well be redundant and out of date, but hopefully it can be of help. Thanks for the shout out, Daniel!
