Bass traps and diffusers

[RoadrunnerOZ]

yes, im sitting 134cm away from them and they are 134cm apart, so this seems to work better, i'll get building somemore traps for the front wall, might make them 10 or 12" deep as i have the empty space there.View attachment 119995

Are your monitors centred to the room ie. each monitor equidistant from its adjacent wall?

 

[Spencerleehorton]

No, as I will need to move the rack unit on the bottom right, but that will involve unplugging everything and moving it as the desk won’t centre in the room with that next to it!!

 

[RoadrunnerOZ]

What about swivelling the rack so it faces inwards and moving it back down the room a little while it’s all connected?

 

[RoadrunnerOZ]

Then you can move your desk across. You need to have the whole system - you included, centred or you’ll have issues.

thats not a bad idea!! but i will still have to unplug everything as the cables ive used are too short to do that, but to be honest it all needs a tidy up anyways so i'll do that then retest.
The rack unit will act as a shelf for my piano on the right it will all be fine and i'll have loads of space!!

ok, now the monitor cones are 75cm from side wall and 63cm from front wall, they are 144cm apart and 144cm goes just behind my ears in mix position.
i will retest now.

Cool

 

[RoadrunnerOZ]

Maybe bring your monitors a little closer together to get them inside the 1/4 position - 120 - 130cm apart so you’re also at the focus.

 

[Spencerleehorton]

speakers are now 120cm apart, 87cm from the sidewalls, 70cm from front wall.

 

[RoadrunnerOZ]

Little dip at 75Hz approx otherwise it looks good. That dip is likely a length diagonal. Tests done with door shut I presume.

 

[Spencerleehorton]

this ones at 130cm apart and 72cm from sidewall

 

[Spencerleehorton]

yes tests are done with door shut and im out of the room

 

[RoadrunnerOZ]

Now try a test with the mic in front of your face

 

[Spencerleehorton]

in front of my face

 

[RoadrunnerOZ]

Not bad overall. Bit more taming of the back end of the room perhaps

this position is speakers 134cm apart and mic is now just before the desk, pretty much where my head would be over the keyboard.

the main change here is i now have 3 panels above my head and ive put a makeshift panel on the floor on the front wall, as below the desk there is a big build up of 120hz, so i could make a few more panels and put them on the front wall, as when i listen this seems to be the culpret.
pretty major change now.

This waterfall looks very good- even the 80 Hz area is below 200 ms I imagine the room is very comfortable to mix in. You may have found a resonance between your desk and the front wall at 120 Hz that any thick absorber would mitigate. Excellent results.

yes the front wall bottom area under the desk is definetly the problem, just need some dry weather and some time to build a few more traps and i think i'll be within a fairly good spec.
I have tried SoundID reference by sonarworks and it did fill in the bits im missing but honestly i can hardly tell the difference with it on and off!! i can hear it changes something but i have to really listen for it.

SoundID (full disclosure, I consult and write for Sonarworks) is great to add the final touches to a well designed room and properly integrated speaker setup. SoundID can nail the stereo image by time-aligning the two speakers and correcting small performance differences between the two monitors.

You can’t fix time domain problems with EQ, so any room modes or reflections will not be corrected by SoundID. Have you experimented with the different phase modes of SounID? I find the “mixed” setting to be the most musical. I love SounID on my speakers and headphones but some people feel differently.

Things have come a long way with software like SoundID and it’s so good to be able to reference with correction in and out and sort some room issues.
In the early days back in the ‘80s there were room correction options for studio monitoring, but most were super expensive and out of reach of most private individuals and small studios. There were hardware boxes which involved a complex setup routine and these then stayed in place in your monitor path - bad luck if you had several sets of monitors $$$.
Companies like Genelec also built correction into speakers.
Back in the ‘70s Philips developed the Motional Feedback speaker which had inbuilt bass correction - I was an apprentice with Philips at the time, working as assistant in the design labs division some days a week and these were a new step into the Hi-Fi market by Philips. A lot of the Hi-Fi nuts pooh-poohed the idea saying it wasn’t a “pure” sound. Funnily enough some of the great albums by Pink Floyd were mixed on these - The Wall, The Final Cut and The Division Bell which I’m sure the same Hi-Fi nuts listened to on their systems.
Trinnov have a really nice correction system but it’s expensive compared to the SoundID and does involve hardware purchase and either renting or buying the special 3D reference mic - I recently did a control room setup with this system, going back next week to do alignment with sub in place. This does all facets of room correction however with phase and time corrections incorporated as well as EQ levelling.

Really interesting info - I had no idea correction goes that far back. I’ve worked with many studios, from home studios, to sun states, to Capitol’s 9.1.6 Atmos room, using all kinds of hardware and software offerings. Trinnov, as you mentioned is effective, as is SoundID, and DIRAC. I’m in favor of hardware-based solutions for their simplicity, but lately I’ve been using Ginger Audio’s Sphere control room monitor software that provides for plugins, bass management, level control, and even delay settings for multiple monitor systems. It is a wonderful time for dialing in great sound.

Many companies are beginning to integrate SoundID calibrations into speakers and monitor controllers and HEDD audio provides a range of speaker voicing options including plugging or opening ports and DSP to adjust associated the LF extension, driver time-alignment, and even desk-reflection correction settings.

Genelec and other companies have integrated tuning options and Dutch and Dutch have even found a clever way to minimize SBIR effects.

Just wait for AI to take over speaker tuning… erm…
