FIR filter Audio object implements a mechanism for time domain FIR filtering. FIR filters are more stable than IIR
filters and can be designed to have linear phase response. However they require a filter of higher order for similar
response as an IIR and hence computationally intensive.
The filter operational mode can be controlled from GTT. The FIR filter coefficents can be provided through GTT custom panel from pre-stored coefficient files in .csv format.
Currently the user can specify the number of elements which is the order of filter. The minimum is 2 and the maximum 1024.
