Is there a thread for beginners on ASIO4ALL?

[2Sunny]

Hi Everyone!

New guy here. On the recommendation of folks over on AudioScienceReview.com I have purchased a UMIK-1 and downloaded REW and just started to learn how to use it. I'd like to learn how to use ASIO4ALL with REW so I can test all 5 speakers from 20-20k and not just L+R hence my first question:

Is there a thread for beginners explaining how to use ASIO4ALL with REW?


I've made some progress already in that I used REW to test my subwoofers and adjust the PEQ1-3 settings on the iPhone app for my SVS SB-1000 subwoofers. I am certain I have made many mistakes and look forward to learning how to use REW better. Below is a screenshot of a measurement I took after adjusting PEQ settings on my dual subs. Sadly I didn't save the before graph to show the changes. They actually were quite dramatic.

Don't use ASIO4All, just select the output device whose name starts with EXCL to access all device channels.

Thanks! That sounds much easier

So just trying that out now. I see all my speakers now but the LFE channel is set to 4 and when I try to test the LFE channel I get nothing. All other channels test okay.

What's the system? How is REW connected to the system?

What's the system? How is REW connected to the system?

I have a Sony STR AZ5000ES connected to a 2024 Lenovo/i9 Win 11 laptop with a UMIK-1 running REW through an HDMI connection. I did get my first 20-20k reading yesterday, and I set the speaker output to 85 dB prior to the measurement using NIOSH on my iPhone. The 85dB setting was using the A channel on NIOSH. Below is what I got with the MDAT file as well. EDIT: The speakers are as follows

Revel PerformaBe F226 - towers
Revel M16 - bookshelf/surrounds
Ascent Acoustics - Duo V2 LCR center
SVS SB-1000 - sub (dual)
