I wanted to ask for examples of IIR filters. I still don't quite understand how it filters it out. It would be better that the filter be good enough for audio filtering. Help would be appreciated. Thanks in advance Last edit by pub_123 at 2 Nov 2021, 09:34 AM ------------- |

If you just want snippets of code you can use, the best place always used to be musicdsp.org - lots of really useful examples but not much explanation. The site went down for a few years and then someone brought it back, it has a new layout but the content is just an archive of the old site. Filters here: https://www.musicdsp.org/en/latest/Filters/index.html If you want to learn about the theory behind them, I strongly recommend The DSP Guide, available here: https://www.dspguide.com/ The whole book is accessible online or can be downloaded per-chapter as PDF. I've read the whole thing, it's fantastic. One annoying bit is that it's a little old, so the examples are all using BASIC but they're easy enough to follow. Another good resource, if you find yourself trying to design biquad filters, is this online calculator: https://www.earlevel.com/main/2013/10/13/biquad-calculator-v2/ That site has plenty of other online calculators and resources too. ------------- |
