Following up on the insightful comments from Fons et al. - The increase or decrease in noise relative to the self-noise of a single mic is often referred to in the literature as White Noise Gain (WNG). This can be calculated or measured for linear filtering operations such as Ambisonics B-for

Hi Archontis et al., Nice work! It’s great someone is taking the time to put together the infrastructure for web-based ambisonics. I enjoyed watching your Intensity Analyzer. How did you encode the raw Eigenmike signals? Using some of our software (EigenUnits-Encoder or EigenStudio), or som

Hi Martin, If you’re already using ambiX, you might try looking at inserting the ambix_converter_o3 plugin between the TOACore outputs and the decoder inputs. It can easily take care of the conversion for you. Note that in addition to channel ordering you also need to convert the normalizatio

Hi, I briefly wanted to let members of this list and users of the em32 Eigenmike(R) know that we just released a set of AU plugins for use with the em32. Currently this includes one AU to control the microphone's programmable gain amplifier levels (PGA levels) and calibration, and one AU to en
