    Calibration Of Soundcard

    Hello Everyone, I calibrated my sound card but the high end looks odd. Why wouldn’t it be a flat line? As you can see it’s affecting the room measurements in the opposite way. Plus phasing look weird.

    Limit design for rew

    How to know the speaker system is hifi? Limit will help you judge. Limit can be added, for example (frequency response, thd, impedance). Limit tool will help you to make limit with measurement results。 In the graphic display interface, it should show pass or fail.. Limit should have at least 2...

    New calibration design for rew

    In order to manage the calibration of multiple devices more easily, I designed such a new structure. Calibration is saved as a group, each group has multiple calibrations, and calibration data of multiple devices can be added (each device can add a sensitivity and a curve). I might design a...

    Import b&k microphone data to rew

    Maybe rew will support bk data in the future? :cool: (import the bk data to soundcheck is working)

    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...

    Newbie DIY Acoustic Treatment - Trying hard :)

    Hi! (Sorry in advance for any language mistake!) I'm quite new to whole acoustic treatment thing, but I'm trying to take it seriously. Since I'm on the budget I just watch as many valuable tutorials and figure out the best way to treat my room. Right now I bought few panels from a local...

    "Birdies" from REW Tone Generator

    While using REW to generate tones for sniffing out room resonances, I've noticed "birdies" from the REW generator while generating low (subsonic) frequencies. The original thread about this is on Audio Circle, and includes an explanation of "birdies" for those not familiar with this effect...

    REW SPL Meter Calibration against C- or A-Weighted SPL Meter

    Dear John, I want to use the REW SPL Meter. For the calibration I was just wondering whether I should set my external hardware SPL-Meter to C- or A weighting. When I hit on calibrate in the REW SPL-meter, the REW SPL-meter always jumps back to C-weighting, no matter if I have set A-weighting on...

    USE of REW RTA for engineering applications

    Hi all, I'm a mechanical engineer looking to do some acoustic analysis of a small device. I cant declare what it is that I am working on due to confidentiality, but I have a pretty solid analogy for it. Imagine a train conductors whistle, which has a cork ball in it to create that signature...
