Hmmm... lots of colleagues around here, it seems. There are a few more I know for sure, but they're keeping silence in this discussion.
I will put drums on any song you like. Wanna hear a sample?
Here... i was setting up a bunch of mics on this low end "too many toms" kit I have in the studio right now and wanted to hear a balance of the kit and also make sure all the toms were making it in OK which is why it's so masturbatory.
https://www.sndup.net/53qmWhat a show off! Want a bit of criticism? All right, OK, I'll STFU.
Well, the timing isn't perfect *runs*
LOL - He didn't play to a click track or metronome, that's why. I was always bad at playing to click tracks, but the groove is pretty cool and shows quite some ambitions.
Trapping in a room with windows is useless.
Better even out the reverb times with Helmholtz resonator panels, gives a natural, not too dead room sound.
Ultimately, you build a floating room in the dimensions you want the low frequency resonances/standing waves to be wiped out.
You'd need some more Bitcoins for that, though
Do you have good experience with Helmholtz resonators? I wanted to have a taste, and I built a "bottle" (box, not panel), but I found the resonant freq can get amplified, especially in the case of a narrow-band Helmholtz box - that is, the ones without any absorption inside. According to my sources, a thin layer of absorption (rockwool etc) inside the box will "smear" the freq response of the device, which is usually desired.
Not willing to invest too much in treatment with an uncertain bang-for-buck factor, or possibly even detrimental, I dropped the Helmholtz project. But if you have a good experience to report, or can point me to reliable sources, I'm totally willing to reconsider. As it is now, I'm fine with my extensive rockwool paneling, but a little more low and low-mid absorption, shorter RF times etc., can never hurt ;-)
I know helmholtz resonator panels only in theory and by listening to before/after room samples.
Successfully using them means precise measurement of the room, to know where which frequency ranges have to be trapped.
Good room were sounding like crystal clear, but more alive than the usual damped-to-death counterparts. I heard rooms with reverb times of 0.3 to 0.5 secs.
Awesome.
Getting rid of reflections from the mixing desks and outboard racks is maybe as difficult as controlling reverb time over frequency bands.
Best listening/recording environment is open space (in the desert for example.
