Hi Sreeraj, I don't have anything constructive to say about things right now. I've looked at the video but have not looked at the code or played with it myself. All I wanted to say was that this is looking fantastic! I'm really happy with the functionality (and future work you've talked about). The flexibility and design capabilities are great. I particularly like the pole-zero plot, both in the ability to see what the filter looks like and how you can manipulate them graphically to adjust the filter taps. I think this will be a great educational tool, now, too. Thanks for the update.
