EJW Posted October 27, 2007 Report Share Posted October 27, 2007 Ok, here's one for you long time Labview gurus. I was writing my own media player in labview, and i thought it would be cool to add an EQ. Unfortunately, i have no clue how to do this. I am assuming I would use and band pass filter to get each band i want, then modify the amplitude somehow, and then, the part i really don't know, is how to combine it all back into one signal. Anyone want to take a stab at this? I'd appreciate any input, thanks much folks! Quote Link to comment

We actually had an Equalizer demo we presented quite often that was part of the examples we shipped with the original DSP boards (waaayyy back around 1990ish - hey, you said "long time LabVIEW gurus"). Yes, it was a bank of bandpass filters. Those VIs are super old so I don't think I have them anymore. When I return from my business trip in a week, I'll make a note to look around in my old things and see if I can find something to help you. Quote Link to comment

PJM_labview Posted October 27, 2007 Report Share Posted October 27, 2007 I don't know if you care about the display side of it, but if you do, attached below is one way to do this. Note: OpenG VIs Required. PJM Download File:post-121-1193433707.vi LV8.2 Quote Link to comment
