Object filter/fir16


#1

Hello,

do anyone know how i can set the coefficients of the object filter/fir16?

thanks

Gunnar

The coef input uses one buffer (16 samples) as coefficients.
You can use "other/bufferindex" + "table/read" to scan a table at buffer rate.
Use "disp/scope buffer" to visualize the coefficients.

thank you very much for you advice. Its very interessting and exciting for me to check the theory behind FIR with a tool like axoloti.

Designing (FIR but also other) filter coefficients can be anywhere between easy and complex. Doing filter coefficient design explicitly in a patch is a bit weird. I hope to have an integrated filter coefficient design wizard in Axoloti one day, but this is very low priority...

i start study again smile

so many things lost over the time.

That's a good DSP foundations book!

table/allocate 32b 16sliders
is perfect for checking how the fir sounds :wink:

maybe i have found an nice tool
