Recommended Posts

Hi Iam writing a software mixer, I want to make support for filtering, but I can't figure out how its done. Ive looked around some and can't find anything useful. I want to know what I should do to an audio signal if I want to cut it for example at 4000khz. Anything useful would be great! thanks

For audio filters, google for IIR and FIR - Infinate Impulse Reponse and Finite Impulse Response. Also look for other audio applications, particularly linux ones, since they all tend to be open source. Look for stompboxes and gtkGEP.

Infact....

There is one link which may help, although in Polish, you will be able to find your way around the site. Oh and http://www.musicdsp.org is a great source for anything digital and DSP!.
