FIR filter

Post by lizard4mg »

I want to process the convolution of an audio input signal with an impulse response. How can I create a FIR filter? Can I introduced the coefficients by using a text file?

Thanks!

If you want to make your own filter then you can use the DSP code component.

If you look inside something like the Moog Filter you will see the DSP code component used at the bottom level.

MYCO released a convolver quite a while ago on the SM forum.. I didn't see it available here yet so check the sm forum search for MYCO and real time convolution.
edit:
It might have been matti that did that convolver?

Yep, me. Hi :D

Though it seems the files haven't been online for a while now. I'll have to see if i have them somewhere.

Edit: I read through the original thread from SM forums (as i don't remember where it was left) and i think it might not be a very good example for FS. If i rewrote it with FS specific tricks it might work better. Maybe a project for some rainy day :D
