    Much better suggestion!!!

    The higher, the number the better. The Mac mini is clearly better than a cheap NUC unit LOL! With 55x, you have plenty of CPU power to spare.

    NULL filter?

    If my explanation was not clear, post your zip file here, I'll modify it for you.

    weird the zip file loads up for me in Roon (under the convolution tab)... Maybe Roon on Mac and PC behave a bit differently? Another way to assess how much CPU headroom you have is to look it up in Roon (see pic below), if the multiplier is below 1 you might run into issues. BTW the filter I...

    NULL filter?

    Ahh! This is going to require a bit of nerding out, but it can be done. I haven't tested it thoroughly but give it a try. So I created a wav file that's an impulse of 1 and has a tap length of 131072. It's a single channel wave file. I Called it null.wav the cfg file looks (in my example) looks...

    NULL filter?

    I think JRiver allows you to do that directly. In DSP Studio, select Parametric equalizer, then add "mix Channel". You can choose a source channel, a destination channel and whether you want to swap one for he other, copy, move, add, substract. So hopefully you can create whatever map you want.

    Here's a Roon DSP filter for the 3 way demo measurement, with 131072 taps, and 96 KHz sampling . I'm sure your Mac mini can handle it. Give it a try.

    Using sub as separate speaker

    Awesome news! See, I told you it’d be worth it !

    Enhancement Request for Next Release

    Thank you that makes a lot of sense.

    Enhancement Request for Next Release

    Here are a couple of other enhancements that would be awesome (pie in the sky, probably not a priority for Bernt): The ability to run a correction repeatedly while varying a variable. For example once you run a correction filter, you would instruct Audiolense to run the calculations again while...

    Using sub as separate speaker

    Sorry it's so much trouble to sort it out. It'll be worth it in the end ! BTW the RME FF400 seems to allow mixing channels to mono (I don't have one and only looked rapidly at the manual, so I might be wrong). see attached mid page under 'mono'. If I 'm right you can send R+L low freq to your...

    Using sub as separate speaker

    A lot of Subs have R+L inputs (they are summed inside the sub) . Does your sub only have 1 single input? Sorry I can't remember the specifics of your system, perhaps that's not an option... If you have time, try running a distortion analysis for your mains and your sub (no DSP) in REW. You can...

    Strange Subwoofer Measurement

    A bit hard to read but I think I see 7 step responses, where there should be 8. I think none of these step responses represent the subwoofer’s step response. Can you zoom out and see if there’s another step response a bit later?

    Strange Subwoofer Measurement

    Hi Jeffrey, Does your subwoofer have an internal DSP? If it does it could introduce a significant delay.

    Confused

    I use a Motu dac. There was a shelf eq in a channel that wasn’t supposed to have one. My routing table and EQ table are a bit out of control (too big) ! The reason I had a shelf EQ in another channel is that my DAC is used as my phono preamp as well. I mix the right and left channels below 150...
