still have a cloud to make and more foam to put up...

i really really like this room. i made the listening place 38% of the way from the wall, and made the speakers halfway between me and the wall. the speakers are resting on stands i made to be at my ear level.

i have 8 bass traps and just a bit of the foam up. the cloud will hang at an angle from the ceiling and will also have foam on it.

the room is fairly dead, but it could use some treatment on welll..the walls that don't have anything on them besides bass traps in the corners.

an extra layer of insulation in the walls and ceiling really helped, and i think it turned out well

That is nice. Looks like you have done a great job!! What kind of piano is that?
 
I'm about to paint my studio blue. Good color.
 
Looks good, nice sized room as well :)

It's cool to see piano, cello, violin, xylophone and accordian with guitars.
 
i think i'm going to wait on the cloud...it just doesn't seem that bad right now...and i'm out of decent foam.

i don't have standing waves from the listening place. basically i only get one when i'm standing in my right corner in just the right place.

this is how she looks...i may record a little something just for your listening pleasure today.

clapping a lot all over the room.

you hear a flutter after the clap.

i kinda have sensitive ears. they get peirced when i clap.


i found more by the door. i should think about puting a mattress there or something
 
Ouch... I was hoping you didn't say "I used the ol' clap your hands trick". You need to test over a wide range of frequencies to determine if you've got standing waves. Clapping your hands does nothing for low freq's.

I don't mean to rain on your parade :) Your room looks really cool.
 
yeah...in my last post i was going to say it was a lame test of a small and high frequency range.

i'll run my signal generator at different frequencies and see how i did.

i basically just did that while i was putting the foam up to see where the most flutter was.
 
at 100 my left corner sounded pretty good. the other corners were pretty pathetic.

at 150 things were a million times better.

200 it was still good.

basically everything on up sounded ok.

100 -80 wasn't doing that great...and i couldn't crank my speakers high enough to test 50. i don't have a sub :( besides the small ones on the side of my speaker.

if you couldn't tell, i'm not too into bumpin music anyways. haha..

its a witzel from chicago. its really old..there's tuning dates written in it from 1915.

and..it was free! i got it from my highschool swim coach years ago
 
> you hear a flutter after the clap. <

Those are not standing waves, that's flutter echo. Not to burst any bubbles! But looking at your photos I am 100 percent certain you have standing waves. It's really easy to prove this to yourself: Simply play a 100 Hz sine wave and walk around the room.

yeah...that's what i did when i checked out the room. (see my last posts)


i know they're there, but from where i'm listening, it's pretty good. my room isn't wonderfully flat...but it's ok
 
and i thought a wave from parallel walls that bounces back and forth was a standing wave.

its not just one echo, you can hear many echos that are really close together.
 
Your mixing position might be in a null, or somewhere between that and a mode. Without some degree of bass trapping you're going to have standing waves. For all the money you spent on foam you could have made some bass traps for a lot less and gotten better results.

Just my $0.02
 
40 on foam/40 on traps ...it's mostly 3 or 2 inch foam. and some 1.5. the 1.5 is probably worthless, but at least it colors the room.

there's 2 8"x8"x2' bass absorbers in the vertical corners. yeah, would need something better thuogh.

and what's wrong with my mix position?

mix-ing position is not the mix-er position. that's just where crap gets plugged in at.

A standing wave is a wave that has some dimensional relationship to your room and because of this, it appears to remain stationary between (or among) the surface(s) from which it's reflecting.
So, yeah, it is bouncing back and forth, although it remains "standing."

So it's not repetitive echoes that you'll hear, it'll be differences in levels in different spots around the room (nodes and antinodes, I guess are the terms.)

As someone already mentioned, the repetitive echoes that you hear are considered flutter echo.

Feel free, anyone, to correct what I've said.

Are you saying you don't have a specific spot from where you listen? If that is the case, then all the more reason for bass trapping.
 
no. i mix infront of the speakers, not in front of the mixer that is infront of a corner.
