About Implementing A Sound Equalizer - akin...@hotmail.com - Apr 20 8:22:43 2008

Hello , 

I want to build a multiband equalizer. I know that I must create bandpass filters for that
aim.

So should they be FIR or IIR filters and why ? 

Is there any sample code in C\C++ for building an equalizer ?
Best Regards,
Akın Öcal

I would recommend FIR filters, as you can avoid phase distortions, and you 
have unconditional stability and protection against overflows.
