Is there a way to calibrate each of those elements (again similarly to the procedure mentioned above) in the application such that the app can automatically remove the test system’s inherent frequency response from that of the DUT?
– in the case of testing a speaker, remove the response of the test system’s microphone from the DUT’s measured response in that system
– In the case of testing a microphone, remove the response of the test system’s speaker from the DUT’s measured response in that system

If you have a reference microphone, which you can assume to have a negligible effect on your measurements over the frequency range of interest, then you can perform baseline measurements to be used for automatic correction in the Dual FFT Analyzer.
When measuring a loudspeaker, you would use your reference mic to measure the loudspeaker directly. When measuring a microphone, you would first perform a measurement with your reference microphone, capture that measurement, and then apply that measurement as a correction factor for your next measurement. For your next measurement, you would then replace the reference microphone with the microphone under test.
When performing measurements on acoustic transducers, like loudspeakers and microphones, extra care must be taken to ensure that measurements are consistent and reliable. Making sure coherence is maximized will be very helpful, but an understanding of acoustics and the effects of the acoustic space, in which your measurements are being performed, will help ensure that your results are truly meaningful.

Each of those elements contributes to the overall measured response, as mentioned in the article above.

Electroacoustics Toolbox currently relies on audio interface hardware (e.g. hardware devices from MOTU, RME, Echo Digital Audio, Edirol, PreSonus, M-Audio, etc) for input.

Is an interface to Matlab supported?

Electroacoustics Toolbox is a Mac-compatible software package, which is independent of MATLAB. However, the Toolbox can export data to MAT-files.

What formats of captured data are supported?

Electroacoustics Toolbox captures LPCM data from the afore-mentioned audio interface devices.

Is an interface to LABVIEW supported?

Electroacoustics Toolbox is a Mac-compatible software package, which is independent of LabVIEW.
