  3. Time it takes to reach the microphone

    REW Forum
    I want to setup my audio system in my car using proper measuring tools. The problem in a car is that the distance from the right speaker is different to the speaker from the left. Since I have an audio processor in my car, I can make a time alignment setting, so I can delay the sound coming...
  4. 4955 Microphone by B&K

    SPL Meters | Mic's | Calibration | Sound Cards
    Recently, we bought two low-noise mics (4955 by B&K) plus amplifier (Nexus 2690), to perform measurements down to 0 dB HL. Their noise level is ca 6.5 dB (A). To make further experiments, I would help me know what kind of mics they are. Attached data sheet does not say that much. Are they...

    SPL Meters | Mic's | Calibration | Sound Cards
    Hi if a mic has a sensitivity of 10mV/Pa can I use this for SPL on the top of the calibration file. If not can I convert this for SPL? Thanks in advance

  7. Uncalibrated dbx RTA-M Microphone Advice

    REW Forum
    I am planning to EQ my home studio where I mix orchestral music. My personal research has lead me to two uncalibrated microphones that have a relatively, flat response curves; I would say, flat enough to use to find major problems in my room, the dbx RTA-M and the Presonus PRM1. I am very aware...

    SPL Meters | Mic's | Calibration | Sound Cards
    Hi all I would like to know if the XTZ microphone pro needs "normal" 48v phantom power. I would be very happy if someone could measure that on the included usb-interface. Thanks. Andy
  12. Binaural measurement + how exactly does REW process L/R microphone input signals?

    REW Forum
    I've followed / used the work of Dr. Earl Geddes to tune automotive audio systems professionally to down right spooky / lifelike results. I used specialized commercially available hardware and software to achieve this. But who can afford this if they want to apply similar principles at home...
  13. Audio recording with REW through calibrated microphone?

    REW Forum
    Is there any way to record short audio files with REW? I am especially interested in this feature, because I don't know which other recording-software would support calibration files for the used microphones. I currently have a UMIK-1 and would like to use this to record short audio clips (up...

  15. microphone calibration by comparison

    REW Forum
    it's probably a stupid question : suppose i have a calibrate micro M1 and a non calibrate one M2 using M1 i take a measure (loading M1 file in calibration space) =>A1 using M2 i take a measure in the same condition ( unloading M1 file of course) =>A2 is the export measure of (A2-A1) represent...

  19. Using Yamaha YPAO microphone with REW

    REW Forum
    Am a new user of REW. Just tried using the Yamaha AVR YPAO microphone with REW, it seems to work quite well (more sensitive than the laptop built in microphone). However, I notice the freq response from 1khz - 20khz drops off about 15db from the lower ranges (20hz-1khz). Has anyone tried the...
