  1. [HELP] Poor Man's multiamplification linearization

    REW Forum
    Hi everyone, as a NPO we're experimenting multiamplification with an HT amplifier (Yamaha RX-V663) that provides a "measurement tool" for calibration (the well-known Ypao microphone). Even if we obviously know that it's not the best method to obtain good results, what level of accuracy do you...
  2. UHD SDR calibration?

    Video Calibration
    Hi all... Been gone a while... Hope all is well... I'm familiar with video calibration at 1080... A friend has asked me to do a new set, 4k, and I figured I'd just get the latest test patterns and go, but it seems technology has passed me by... I've been reading up, but it seems I'm missing...
  3. Soundcard calibration

    REW Forum
    So it's been a couple of years since I've played with REW and it's showing. New computer and I can't seem to get a good sound card calibration. I have a simple stereo headphone to stereo headphone jack going from the line output to the line input on the computer. Here is the soundcard...
  4. Question for someone who has intimately familiar with how auto calibration software works.

    Electronic Processing/Equalization Devices
    I have always wondered why all (at least the ones I have played with Audyssey, MCCAC YPAO) the auto calibration software seems to only run a single pass per channel? Yes I know some of them will allow you to adjust the position of the mic and run multiple passes but that is not what I am...

I just purchased a Focusrite 2i2 USB and I want to make sure I am doing the REW sound card loopback calibration correctly. I was expecting flat response out to 20k the low...
  10. Need advice toward my first calibration plan

    REW Forum
    Hello everyone, I have downloaded REW in my MAC. I am excited to run some tests but don't know where to start. Equipments I own: 1. MiniDSP mic, calibration file was downloaded. 2. A surround sound processor. 3. Full range large L/R speakers, center, 2 subs. I would like to calibrate a 3.1...
  11. Hi Hello and first Question

    REW Forum
    Hello all, this is my first post. Is anyone able to help me find a calibration file I can use in REW for a Radioshack SPL meter? My model is analogue and probably 10 years old (although I can't remember when I bought it). I've spotted some correction data in the forum but wouldn't know how to...

    SPL Meters | Mic's | Calibration | Sound Cards
    Hey there, I got my measurment kit since 10 years. It was calibrated by a company that no longer exists. I tried to convert the cal in exel to a 90 degree one like this one in my picture. Don't need that 100% correct. It's just more convenient to measure in 90 degree. Anyone could help me...

  14. IR export--deconvolving by soundcard calibration

    REW Forum
    Good day, I can't find an answer to the question how to deconvolve the exported impulse response using the sound card calibration in REW. From my experiments, it looks like by default REW doesn't do it. Here is what I tried: 1) Calibrated the sound card 2) Made a loopback measurement -- the FR...
  15. Microphone calibration file in REW

    REW Forum
    If there is a better thread for this type of question, please point me their direction. I'm trying to learn REW to do some room treatment measurements, and have a question about calibration files. I have a Dayton EMM-6 microphone that I purchased through Cross-Spectrum Labs, that came with...
  16. Wonky measurement- calibration to blame?

    REW Forum
    I’m in the early stages of incorporating acoustical treatment into my theater. I downloaded the REW software with the intention of using it to identify a relevant baseline to compare post treatment results. I’m running windows 7, am using a Radioshack 30-2055 SPL meter and a BehringerUCA202 as...

  18. UMIK-1 SPL Calibration

    REW Forum
    Hi, I bought the Mini DSP UMIK-1 microphone and when comparing the SPL meter in REW to the classic radio shack SPL meter, the REW measurement is 5db hotter. I have the correct calibration file loaded for the microphone, could it be something else? Thanks, Sean.
  19. Enlarging the notes window for calibration measurement using loopback

    REW Forum
    I can't seem to enlarge the notes window for calibration measurement. I guess its kept intentionally small, to allow multiple measurements to be tabbed. When doing a loopback cal then there are a lot more details than the notes window size can show, especially for the soundcard setup. Yes I...
