 CharlieLaub Offline Premium Member Posts: 113 Thank you received: 8 knuisje, Thanks so much for posting your spreadsheet (in post #1118 ) that can calculate the MiniDSP Z-transform transfer function coefficients. I had developed a very complicated crossover using the Laplace Domain transfer functions, but obviously could not enter those coefficients... I would have been stuck... so thanks again!!! One request, however, as you are missing two important filter functions: the FIRST order shelving high and low pass filters. Any chance that you could add these to the spreadsheet??? -Charlie Please Log in or Create an account to join the conversation. Last edit: by CharlieLaub.

 dreite Offline Platinum Member Posts: 1656 Thank you received: 739 Charlie, Those first-order filters can be programmed without using the advanced biquad capability. Just select a normal high/low-shelf and Q=1. Cheers, Dave. Please Log in or Create an account to join the conversation.
