Great :sn:

I plan to buy the Behringer UMC22 so the I guess it will work fine because it's just a "smaller" version of the UMC204. UMC22 have 1/4" output and input compared to the UM2 with rca output and 1/4" input, so I don't need to buy extra adapters.

Sorry for asking again -> But has someone else tried a Focusrite Scarlett with REW ?

I am not even able to calibrate the soundcard ...

somm
While I was getting ready to add my setup, I noticed your post. I'd be glad to help if I can.

I used/reviewed the Scarlett 2i2 with REW on both Win and Mac and recommend it... I gather from past posts you are using the 6i6? If you are on Mac, please see the input workaround on OSX thread.
:hail: A very big and gracious THANKS for your review with procedure info. Helped me immensely!! :hail:

My Measurement setup for REW5.01 and Windows 8 running on quad-core i7 laptop with 16GB memory and graphics accelerator:
  • Focusrite Scarlett 2i2 mic preamp / USB audio interface
  • Dayton EMM-6 fully calibrated by Cross Spectrum Labs
  • Radio Shack digital SPL ,meter (BTW I heard the analog versions were better)
  • Generic boom microphone stand
  • Mogami & Audioquest cables, splitters/adapters
  • Johnson 40-6174 torpedo laser level
  • Audio Control R-101 RTA and Broadband Pink Noise Generator
  • Various Test CD's including Real Traps 1Hz -increment bass test tones

I have successfully gotten REW and Holmsresponse to work with this arrangement:

Behringer UMC204 USB interface
calibrated Dayton EMM-6 (was using an un-calibrated Behringer EMC8000 but sold that as it had a lot of low frequency noise).
I have had a lot of success using ASIO drivers. A few tricks to be aware of. I was completely unable to use ASIO 4ALL, the drivers didn't work for me. Just use the latest ASIO Behringer drivers. I can get 96khz sampling rates in REW and the Java drivers in REW will limit this to 48khz sampling rates.
Also, the unit can be a bit temperamental so I use a dedicated laptop and make sure I always plug the USB connector into the same USB port - hard to believe but swapping USB ports can screw things up!
As a note, the frequency response of the Behringer is 1-db at 5hz and 50,000hz (from memory). I did the feedback loop calibration and to be honest I don't even use it whilst testing as it is well beyond the limits of my speakers anyway. I guess if I was testing a subwoofer I would use it.

On another note I have noticed that this unit seems to suffer a lot from latency problems. Even at "safe" settings using ASIO drivers, whilst listening to music, there are small glitches in the audio stream about once every 10 seconds and there is some smearing of the sound. Luckily I can use another USB DAC for the purposes of listening to music but based on my experiences whilst I would recommend it for speaker testing, I would not recommend this unit for listening to music.
Thanks for suggestion to use the Behringer ASIO drivers, I will have to try that later. I was trying to use REW with a umc204 card, an emm6 mic and ASIO4ALL HDMI out. The level check sorta worked for a few seconds then an increasing amount of noise was generated. I am not sure if I ever did a full sweep with that setup as there are still some problems.

Does the Behringer ASIO drivers support HDMI out? If not are there any suggestions or work that can get the ASIO4ALL to work with the Behringer UMC204. I assume fixes would require updates to ASIO4ALL, I can loan the UMC204 if that helps.

ASIO drivers for a device only support that device, the only outputs the Behringer driver will support is those on the card. ASIO4All creates a synthetic ASIO driver that actually talks to devices via the Windows drivers for the device or devices selected.

I tried everything again and this time everything worked. I am not sure of the difference except may a different USB port.
To summarize
Behringer UMC204 worked with ASIO4ALL and Behringer ASIO drivers including using HDMI out on the ASIO4ALL drivers. It also worked with the Java drivers.

Thanks for your notes and thanks to those who worked on REW and ASIO4ALL.

Hi I am using a M audio fast track pro USB pre . When i try to do a calibration it dosent show me a flat response on the REW. it shows a slope on the frequency indicating that the low frequency response is poor . The same unit tested with another software shows a flat response what could this be due to

I downloaded the REW, but was confused on how any adjustments I made in it would translate into all (or at least components aside from laptop) of my system.

After seeing the gear some of you are using, does connecting it to a beringer like many of you have allow you to get the adjustments the software makes into your AVR, DVR, PS4, Oppo?

Probably need a screenshot to know whether what you are seeing is normal. When comparing results for different programs make sure the graph scales are similar - REW uses a highly zoomed in SPL scale when looking at the loopback response, for example, so what looks like a large slope may be just a few tenths of a dB from flat.

If you want to apply REW's EQ suggestions you will need an external equalizer of some sort Behringer or miniDSP for example), or EQ filters in your processor, or a software EQ such as EqualizerAPO if you are playing audio from your PC.

Need external soundcard advice!.

Looking at an ASUS Xonar U5 5.1 Channels 24-bit 192KHz soundcard. Works with WIN 7 on my laptop and I already have the Behringer ECM8000 mic and a Sound Devices MP-1 pre and phantom power supply. With ASIO drivers the latency is supposed to be 2ms and FQ of 48K.

My other option is a Creative Sound Blaster X-Fi Surround 5.1 Pro USB Audio System with SBX SB1095 24-bit 96KHz.

Any thoughts? Thanks for the advice!!!

I'm expecting a Behringer U-PHORIA UMC202HD 24-Bit/192 kHz USB Audio Interface this week will do some frequency plots on that.

Grateful for your help, greets

Are the Focusrite Clarett series soundcards compatible with REW?
I'm interested in the 4Pre model. It looks to have a Thunderbolt interface instead of the USB. Is that a problem? My laptop is Asus Zenbook UX31A and it runs on Win8.1. I have been using M-Audio Fast Track Pro with REW for years before, but now I would like to upgrade.

EDIT: I just found out that the Clarett series is currently not compatible with Win8.1, which is a bigger problem in my case. Still, I'm interested in the REW compatibility for the future plans.

Thunderbolt cards are aimed at OS X, although it is possible to buy Thunderbolt interfaces for PCs. It would be much easier to go for a USB interface, but there's no need to change if you are only using the interface for acoustic measurement - making measurements places quite modest demands on the soundcard and just about anything can do a decent job, no need for a high end interface.
