[QUOTE="Mark DeArman, post: 39934, member: 950"] Re: Well, THAT's Not Gonna Fucking Work! Well I reproduced the phase response in the HF now. The error comes from a one sample difference of the t0 to the impulse response of the HF LP filter type response of a DSP. I'll produce the results here in the forum later on. This is what I was wondering about originally. The t0 choice can dramatically effect results with SMAART or when other measurements which determine the frequency response from the FFT of the derived impulse response. I would like to also point out that I will make available all algorithms and programs which I used to make my measurements if requested. I can't pass out the swept sine programs but the algorithms I will give away for free. In fact they are on [URL="http://www.cascadeacoustic.com"]www.cascadeacoustic.com[/URL] in the tutorial section. The Lock-In Amp program from Feldman I will pass on if anyone wants. P.S. I'm not trying to sell any product to the sound reinforcement industry. I don't want anyone to think my website plug is against SMAART or SysTune. Course I'll bet on the SysTune measurements all day above others. I'm still trying to get a SMAART system down here... duh this is taking like a week... too long. We have five licenses. [/QUOTE]
