    miniDSP + UMIK Input Conflict

    I don’t know if this is a MacOS or REW setting that I need to resolve. When connecting both a miniDSP 2x4 HD and UMIK-1 to separate USB-C inputs on my Mac, only the miniDSP appears among the REW inputs. I can’t access the UMIK-1. Same on the Mac MIDI Settings utility. Given both devices are...

    Two UMIK-1 mics?

    Hi All, I am wondering if it is possible to use two UMIK-1 mics with REW and a PC to speed up measurements? I know that there is licensed multi-mic version, which is not really meant for multi Umik-1 config but I wonder if I could have two of them in two different positions in the room and...

    I would like to compare delay of signal passing through subwoofer to delay in stereo speakers. Purpose is to align the signals in the crossover point using phase adjustment on subwoofer. Can I use REW with only a Umik-1 from minidsp for this? I'm completely new to REW and it seems like the...

    Two UMIK mics with very different low-dB spectrums. Have you seen this behavior?

    I am aware that Mini-DSP has modified newer UMIK-1 mics, to 'alleviate' the USB noise spikes (and that this isn't a problem when analyzing a speaker). I -didn't- know this until I purchased a newer mic... and measured these two very different noise levels. I have ordered an SPL meter, to...

    Absolute dB SPL calibration of digital MICs

    A digital MIC with calibration data has the enormous advantage of NOT needing an additional calibrator. (Of course the provided CAL-data has to be correct). A digital MIC like all USB-MICs may be used as a calibrated Sound Level Meter right out of the BOX (after applying the cal-data and an...

    Feature request? Subwoofer phase measurement with band limited timing reference

    tl;dr: Is there a way to band-limit the acoustic timing reference e.g. to 80-120 Hz so the data makes (relative) sense when crossing a sub to the mains? Hi there, quick Intro first: my name is Robin. I'm from Germany and I was bit by the HiFi bug 20 years back, when an old car battery, car...
