Creating low pass filters help!

GBNvKGBNvK Posts: 2Member
Heya all,

I am researching the theory behind low-pass filters, and I want to write a program that will take in a WAV file, allow me to change the low pass and stop pass elements and basically rewrite the WAV with these changes. I have looked on the net for help but I cant find any information that doesnt contain big algebraic equations.

Can anybody point me in a direction for a relative newby at audio programming ?

Thanks,

GBNvK

    What language do you need to develop it in?

    Heya Gaashius...

    I will be writing it in Blitzbasic as this offers extreme ease of use with speedy results :) Basically, if any code examples are forthcoming then I suppose it would be cool in some kinda psuedocode, but I can read C. :)

    Well I leave this question to the others... since my english is terrible, I hear Blitzbasic first of here. Low pass and stop pass elements are somekind of first heard also - maybe I know what do you think, but I don't know what are them - since I teach everything myself(And usually in hungarian).

    I'm afraid that a BASIC type language cannot hold such PL forms as C does, I mean here about built-in assembler, etc. I hope others can give you good answers. Or you could tell me what's that low pass and stop pass things - I could help maybe maybe...

    i'm assuming since you just want to write wav files, that your not concerned with speed (i.e. assembly inserts). Here's good site for
    simple audio in ansi-type C++. Includes all sorts of useful tools.
    check it out:
