Read this if you have a multi-channel version of WinMLS, if you are using multiple microphones simultaneously and want to correct for the magnitude frequency response of each microphone.
This is implemented using the _ch tag used for other multi-channel parts of the software.
We will give an example of using four microphones, but it is very similar for 2 or 24 microphones.
First generate a set of compensation files like explain in the section above. The filename must end with _ch and the channel number:
In the example above the microphone is obviously four Neutric 3382. If you have microphones of different brands find a common name for them since the name part in front of _ch has to be the same. This is because WinMLS supports more that one set of multi-channel microphones and uses the name part to keep them apart.
Move these files to the WinMLS subfolder named Microphone Compensation.
These will now be displayed as a single item named as neutrik3382_MultiCh1-4 in the list box shown below. Set this as your selected choice.
Now you have seperate microphone compensation for 1, 2, 3 and 4 channel measurements.
Important note: This compensation applies when performing multi-channel measurements, but it will also be applied correctly when opening .wmb and .wav files measured using WinMLS as well, since the channel number is stored in the file header and WinMLS will use this info to find the corresponding microphone compensation file.
