Move fset() and any other custom function to a utils folder. parfilt should go there, too.

Add everything that happens in the browse_ir_pushbutton_Callback to path_ir_edit_Callback.

In case the anechoic testing signal has a different sample rate than the impulse response, add a resampling method to handle this issue.

Include only the necessary parfilt functions used in the app.

Audio signals that are being saved (i.e inverse, equalized), have a variable dB difference with the audio signals reproduced outside the app with the same coefficients.
This is caused by the normalization on the magnitude inside the app for the purpose of better visualization.

Update
If no normalization takes place, then the audio signals to be saved will possibly be clipped.
Leave this issue open, until I give it some more thought.

Check the normalization process throughout the application.
