So, a friend is helping me measure and run the A1 Evo script, I have the UMIK-2 mic, my setup: Fronts: Paradigm Founder 80F Center: Paradigm Founder 70LCR Surround: SVS Ultra Evolution Nano Subs: Dual SB-3000 Marantz Cinema 50 I'm using the following settings in REW v5.40 Beta 73: I...

Hi everyone, I'm new here. I’ve just bought a Dayton Audio iMM-6C USB-C calibrated measurement microphone and I have a question about how SPL (dB) is calculated. The calibration file of the microphone has in the first line 1000Hz -37.4 that i suppose it's the sensitivity at 1kHz. However, since...

Hi to all, I have built a boombox inspired by Paul Carmody – Isetta. Since it was an old project, I’ve done my twist to it link. Being a maximalist (very, very bad thing), I have ordered an Umik-1, downloaded REW (in order to measure it like I’m building a spaceship) and guess what I am stuck...

I have a digital piano, but at the moment, I can only use it with headphones because my room has poor acoustics—particularly an issue at 130 Hz that coincides with the C3 note. Implementing acoustic treatment is not a viable option due to financial and space constraints. For this reason, I’ve...

Hi everyone and happy holidays! I know people ask the question and there is some debate back and forth about EQ'ing/room correction over 500 Hz. From everything I have read (which likely isn't even scratching the surface), it seems like more people believe we shouldn't EQ above 500 Hz. Okay...

Hey folks! I am currently studing Acoustical Engineering and as part of an project we have to messure different churches to make a database for our area. Our goal is to get data in form of RT30/RT20, EDT, C50 and C80. We´ve already messured a smaller one (Volume around 3200 cubicmeter) and had...

Hey Guys, I'm really not an Expert of Measurements or Room Acoustics.. I'm just a Music Producer / Singer-Songwriter from Germany and I want to get my Room sounding right with DIY Treatment trough try & errow.. I did a few Measurements in REW of my Room and also placed the Measurement Mic...

I am buying a 2 channel stereo system that consists of an integrated tube amplifier, and a streamer/dac that has no room correction, and speakers, where all these sound great together. My brother also has the exact same system and it sounds great both at the stereo shop and his house. The...

Hi everyone, I am just getting into room measurement, so first of all, I would like to not overexpend since this is just for personal use for now, and I don't know if this is something I will continue doing. I am looking for a calibrated budget microphone to use mostly with REW. My options for...

Hello fellow madmen (and hopefully the occasional female), I have lately been, rather intensly, watching the great Youtube videos of "Obsessive Compulsive Audiophile" (user @OCA ), a by now well-known Frankfurt genius :) He shows in detail how to correct for speaker/room deficiencies/influence...

I recently built an extremely strange room in my studio with dimensions 16’ x 8ft x 6ft. I have about 5inch thick acoustic panels on all sides. The goal was to see if I could get something that acted anechoic without caring about frequency response/bass buildup… almost like a radio booth...

As you can see from the attached graphs, switching to L+R from L only changes main speakers' measured SPL but not subwoofer's on REW measurements. The subwoofer is SVS 3000 Micro, connected to my KEF LSX II LT via its subtout. I don't think this behavior is normal. Denon AVR-X3800H, which is...

Hello All, I am unable to decide on the placement of centre channel. I am keeping the centre channel of top of TV cabinet and moved it edge of the cabinet. I even raised little bit with door stoppers so that it will be pointing to ear height. Today i took measurements with REW and i see that...

I have a spare TacT Mic. I was wondering if what device I need to connect to the computer to run a REW software scan. I am just weighing if I need to buy a UMIK-1 or this converter for REW software. Thank you.

I am a big fan of Equalizer APO/Peace which I use for a long time. Only a few days ago I started with REW as well. I can play with REW, and for example use the "Audyssey One Evo" script (for Audyssey calibration on my AVR), and among many things that the EVO script does, it enables me loading...

I'm currently trying to figure out how much room gain i get in my "casual movie watching/gaming room", so that i can choose a fitting subwoofer for some infrasonic Bass, when I've got some money saved up. My room is 4.5m x 2.7m x 2.5m -> Room Gain should start at ~38Hz. My Though process was...

Hi, I got myself a pair of subwoofers that I'm trying to setup together with my main speakers. B&W 804d2. Subwoofers are B&W db3d and db4s. I have started out with just 1 subwoofer the one I got first db4s and try to find proper phase and volume together with my mains. The orange line is with...

where can i find the measurements (REW) of the best studios in the world, pre and post acoustics, pre and post eq i have my room measurements and want to compare data like clarity and rt60 and more. above all where can i find the expected ideal listening room measurements / settings to be such...

I have a MiniDSP HTx with full range Dirac Live license. I am using it to drive a 2.1 system at this stage via toslink input. If I use REW to generate 10 PEQ’s for the mains and do my best to phase align my sub I cannot seem to get a good result. I have conducted 1000’s of MMM or sweep...

Hi, Recently I bought a second subwoofer for my stereo setup and I want to ask you about proper measurement process to get things optimized. The setup consists of KEF R3 speakers and two Arendal 1961 1S subs crossed at 80 Hz. Amp is Lyngdorf TDAI-3400 with DSP room correction built in. The...
