Applications

Operating System Name Description Version Release Date Download
OS X EigenStudio®

A standalone application to control the Eigenmike® microphone hardware (PGA gain and calibration) and beamformer processing. Functions such as steering, changing beampatterns, recording and monitoring inputs and output, etc. in a very intuitive manner are provided. Plus up to 4th order HOA encoding and very basic audio file editing.

2.8.5 Apr. 28 - 2017 Download
OS X em32setGain

The em32setGain application provides a simple interface to control the Eigenmike® microphone array hardware (PGA gain and calibration). This allows for the recording of calibrated microphone signals at optimum levels with 3rd party DAWs (Don't use em32setGain together with EigenStudio® since the latter one provides its own hardware control).

OS X EigenUnits®

The EigenUnits® plugins comprise a set of standalone Apple Audio Units (AUs) that can be used in conjunction with the em32 Eigenmike® microphone array hardware. Currently available plugins: 1) EigenUnit-EM32Control: controls PGA level and sensor calibration via the em32/EMIB hardware. 2) EigenUnit-Encoder: encodes the sensor signals into 4th order Eigenbeams (HOA signals, spherical harmonics). 3) EigenUnit-Beamformer: applies beamforming, with control over pattern, order, and steering direction. 4) EigenUnit-HFExtension: improves the performance of the Beamformer above spatial Nyquist.
