Hallo

I am trying to implement my first experimental audio plugin using JUCE. I wanted to create a FIR filter, where the coefficients will be provided by me. JUCE has a class for IIR filters and i can make IIR filters easily using that class. Has anyone tried making a FIR Filter in JUCE? can you give me some idea or code for the FIR filter in JUCE audio plugin

just keep an array of floats with your coefficients and, then, do the filtering. for each sample: multiply and accumulate.

You'd be far better off asking this type of question in the DSP and Plugin Development Forum.

You could just port or re-implement one of these, it's fairly easy to do.
