Hi John, than you very much for your fast reply. The IR is used as guitar cab IR in a guitar modelling unit. Due to limited DSP power in real time and for the sake of acceptable latency those files are pretty short, 140ms is already a pretty long IR, most units use half (or even shorter). That...

ok, after few headaches I found my mistake. the mistake was in my algorithm. The strange sine came from a stupid wrong cutting, was no noise. But now I face another (for me) strange phenomena. When I just process the data FFT and extract the IR the frequency response looks pretty good from 150...

Inspired by REW I started working on a little DSP programming myself. I was reading lots of theory and actually I am pretty happy so far with first results of my little app. Overall the IRs done by the app seem to look pretty close to the ones done with REW, with few differencies which I dont...

Hi John, thank you very much. I start getting doubts about the "minimum phase" topic. I actually came to the IR topic through guitar cab (and amp) modeling. Here is "minimum phase" a pronounced and often "discussed" topic. Even those commercial package of IR files which one can buy almost all...

I just built a little own application for measuring IR impulses for cabs. I actually did this with pleasure using REW for a while but since I needed to automate the microphone position relativ to the speaker by a stepper I neede a way to trigger measurment-movment automatically. It took me a...
