  1. How to connect a diy audio signal to my “expensive” audio interface

    DIY Audio
    I'm a hobbyist and after some experimentation (around 4 years) I want to connect my signals I create on the breadboard to my expensive audio interface. Until now I was using the "mic" input on my laptop to connect the signals and I haven't damaged it. I'm using a 40k resistor in series with each...
  2. Audio interface for impedance measurment

    REW Forum
    Hi all, A while ago I purchased a Behringer UCA202 that turned out to be fake ( eBay). I tried to use it with my DIY jig (using two 5 ohm non-inductive resistors in series) and I could not get the thing to work without noise. Eventually, I went to a friend to use his Dayton DATs to get out the...
  3. Need USB Audio Interface to be Stable with ASIO4ALL

    SPL Meters | Mic's | Calibration | Sound Cards
    My interface is not stable in multi-channel mode using ASIO4ALL with REW. I'm able to direct test tones to each channel individually and in combination, albeit with much switching noise in the process. At its best, the ASIO4ALL driver gets reset, forcing an REW restart or laptop reboot. At...
  4. Extending REW to import custom data files

    REW Forum
    Hello, Is there a way to extend REW to import custom test data? Does REW provide a plugin interface or programmers API? We have legacy data from APx500 measurements that we'd like to import directly. Currently, we have to save the APx500 project data to *.xlsx (with multiple Excel sheets)...
  5. USB audio interface (sound card) comparison: M-Audio, PreSonus and Steinberg

    REW Forum
    I was looking for a USB sound card (aka audio interface) that had decent THD measurements for low frequencies. The Steinberg UR22mkII seem to beat the competition when I tested it in REW against the other interfaces listed below. I chose the three I tested because they were all locally...
  6. I need to access the digital I/O of my interface within REW

    REW Forum
    I need to access the digital I/O of my interface within REW, but I cannot find any method of doing so. OSX 10.9.5 REW 5.1 The configuration of my audio interface doesn't allow the default inputs to be swapped. I've tried Soundflower with no luck. Any tips?
  7. Calibrating audio interface

    REW Forum
    When calibrating the audio interface, instructions say to connect the line-in to the line-out jack. Why not connect the line-out jack to the XLR mic-in? Aren't those the ports that are generally used when performing measurements? I have a Tascam US 322 with Dayton EMM-6 microphone. Thanks, Six.
  8. using REW with Steinberg UR824 interface

    REW Forum
    Thanks for providing the public with a world-class set of tools in REW. I am using a Steinberg UR824 interface connected to a Windows 8.1 Professional computer as the primary interface in a studio and would like to utilize it as the basis for REW measurements. I have an observation and a...
  9. Interface recommendation

    REW Forum
    Ive just started using REW. I picked up the Presonus AudioBox which was priced right. However, the cross talk between channel 1 and 2 is unacceptable. Using Channel 1 for the measurement mic, 2 for playback. Even though channel 2 preamp is turned down all the way, i can hear my voice if...

    Best Interface With REW/Pic's Added I think my M Audio Pre II is going south on me and I may need to another, any advice as to which will give good results without breaking the bank?
  11. Calibration audio interface graph

    REW Forum
    Hi, I've finally managed to calibrate the RME UCX interface. At the beginning I was getting a really strange readings due to the stereo width in the TotalMix..ouch :). Now the soundcard calibration are fine, although I am puzzled what does represents the bottom curve? For the test I am using...
  12. REW 5.01beta17 interface bug

    REW Forum
    Hi, Not sure where to post this, but I guess here is a good a place as any. REW has a small interface/controls bug. When I display an ETC envelope and select a filter (in the bottom-right corner of the graph), the ETC smoothing is gone, even though the setting still says 1 ms (for example). I...

    REW Forum
    Hi John:) Would you recommemend the Focusrite Scarlett 2i2 2 In/2 Out USB Recording Audio Interface for my first steps using REW with the eventual aim of building a 600 litre sonosub with Aurasound NSF18 driver please? I am basing my selection purely on Amazon customer reviews some of which can...
  14. Graphic interface bugs

    REW Forum
    Hello! This is my first post here and I'm relatively new to this area of hi-fi. I have a MiniDSP, UMIK-1 and a computer which has REW. The problem is that the graphic interface goes haywire in REW. Here's some screenshots explaining what's happening: http://i.imgur.com/6eKQyoI.png...
  15. preferred Midi interface, REW->BFD, DEQ, FBQ ??

    REW Forum
    Hello Gents, Was trying to find the latest midi USB interface everyone prefers and where to buy. I've tried several times with an older (2yrs) roland UM1 to interface between a windowsXP laptop REW and BFD1124P. I'm usually pretty good with PC's and device driver problems, but this one was...
  16. New audio interface... what's the difference?

    Pro Audio
    Hello! This is my first post :) I was sent here because of the REW which I wish to use in my little home studio. I bought a dbx RTA-M omni directional mic for this purpose, still need to invest in the SPL meter. In any case, this wasn't the reason for the post. I'm an EDM producer and for...
  17. Using REW on laptop...USB audio interface?

    REW Forum
    Hello everyone; new to the forum: I recently downloaded REW. What a thoughtful, fantastic program! My question is: I plan to use a laptop for EQing, etc various rooms. As you know, they only have a mic in and headphone out. What I'd like to know is if I can use a USB audio interface (ie...
  18. TASCAM US-200 USB Interface

    SPL Meters | Mic's | Calibration | Sound Cards
    I know that the TASCAM US122MKII is one of the gold standards that is used for REW. That being said, the reviews in terms of reliability leave something to be desired. I last looked into this a couple of months ago and I am looking at the process again. That being said, TASCAM makes the US-200...
  19. Which audio interface?

    Pro Audio
    Hey everyone. I'm in the prep stages of setting up a small home studio for my personal recording projects. I do not not need high I/O count and will not be recording entire bands at one time. My preference for connection due to mobility needs an low latency requirements leans toward firewire. I...
  20. USB interface power?

    REW Forum
    I have read some threads that recommend using a laptop computer on battery power to avoid noise issues with REW. Has anyone had any noise problems using any external USB/preamp interfaces when using them with their factory supplied external AC/DC power supply? Thanks!
