Is there a REW setting to play the test tones on all the speakers connected to an AVR and measure the resultant audio at the MiniDSP mic? Thanks!

OK. I discovered the issue. As I mentioned I was using a splitter that had 3 RCA plugs off of the TRRS. As it turns out Video TRRS uses a different connector pinout than audio TRRS. The ground band and the microphone band are swapped. So I was using a TRRS splitter that grounding the mic...

Not a mic icon. But I get this pop up window for example when I plug in a pair of earbuds/mic and the same window when I plug in the splitter and then I have to select one of the options.

Understood. The splitter I have has RCAs. I have another different type arriving this afternoon and Ill try it and if it doesn't provide loopback there there is still some oddness about the laptop to figure out.

Sam: Thanks so much for the thoughtful and incredibly detailed instruction set. I carefully followed the procedure, but still cannot get any audio loopback thru the mic. The output is at -12dbfs but no comparable levels on the input. I can see an audio noise floor at -75 dbfs from the mic...

I have a Windows 10 Dell Laptop. I'm trying to REW to do a simple loopback to characterize the onboard audio. I have attached a splitter cable to the laptop's headphone/mic connector and connected audio out to mic input. Using the Sound Card Check Levels I cannot get only an output, never an...

Ahh thanks!. I was able to muddle through it by trial and error selecting the few input options. Ultimately I selected a USB device as the input that was actually a video capture card, HDMI to USB, that connected to the USB on my laptop. I was comparing microphones for security cameras. I...

I want to compare audio from several security IP camera microphones. I can view and hear audio over IP using a Network Video Recorder or via pass-through device that takes HDMI (input to the NVR) and passes that over USB to the laptop (Windows 10) where I can view on hear audio on a windows...

See the attached graph. I get huge variations especially above 400hz. Its same on 7 different speakers in a 7.1 setup. I must be doing something wrong. Any ideas? The setup diagram is attached. It was a sinewave sweep from 20 to 20,000, 4MB. The setup was

I was able to get multi channel working with the ASIO driver you originally suggested. The key was I need to plug in HDMI to the receiver in order to see multi channel and now I can see them in REW. Thanks for the help. This should get me on my way!

yes thats it. Both 16 and 24 bit work with the Denon receiver. Thanks so much John! Robert

I cannot play .wav files created by the Generator. Devices report the files are Unsupported Format. From the Generator I created a .wav file (20-20,000 Hz sweep, 48Khz, 32bit float) and saved to USB thumb drive. When I attempt to play this file on 2 different devices (Denon AVR-X4500h and Sony...

ok thanks! I'll play with that and see if I can get it work with a REW sweep file. If I can create a file with a duplicate sweep file in all 7 channels, I could simply only connect the speaker I want to measure and disconnect all others..

Ive discovered my receiver (Denon AVR-X-4500H) does not have a analog input that would allow me to use REW as a audio input to selectively test 7.1 speakers (it has pre only for stereo). The HDMI multi channel approach, using ASIO4ALL v2 wont work for me as my laptop sound card only has stereo...

Id like to do that. My Radio Shack SPL meter has only 10db ranges. Im hoping that when used with REW that it extends past that since I have that 20db dip
