IIR Filter example
How about a 31 band EQ using IIR FIlters.

I think that importation or duplication of the microchip DSP library is in the plans, and that includes IIR. Doing a GEQ wouldn't be that difficult once you have the IIR, but you've got to get the audio in and out of the dsPIC. They have a codec interface for that purpose. I wish the dsPIC had enough RAM for an OGG decoder...

That's great!

zristic,
Ok great. Because I gave you the weekend off I will allow you a few extra days to get it ready.

Any progress
Hi zristic,
How's my example comming?

Slow but sure
Ok thanks!
Re: Any progress
Essential for Pascal, but not for IIR. I don't believe that any of the DSP algorithms can run on the dsPIC using floating point, and be fast enough for audio.zristic wrote:At the moment we are implementing floating point, which is essential.
If you know what you're doing, you're not learning anything.

We are coming back to the topic again... It is chicken and egg question, therefore we will make a chicken and an egg at the same time, so all roosters will be happy.LGR wrote:Essential for Pascal, but not for IIR.

Another proud user of LV 24-33A Development System and mikroPascal PRO for dsPIC :)
