Now I understand how easy it can be to mix a song! And the sound... it sounds exactly as I want it to sound. Soft, nice and warm without loosing the punch and the presence. After a rough mix all I had to do was to adjust some minor reverb and automation levels and I was done!

If someone is interested in hearing the result I can post the mix tomorrow?

I'm so happy, so happy!

Happt I want to be!

Please go back one page to see my graph over the room. Feedback would be awesome!

[xmostynx]

hey dim- those graphs look nice! exp. in the low end...
i heard down the line that we actually hear is more representative (visually) if you put a 1/3 octave smoothing on that graph..

as far as i can tell tho your room looks fukkin good!

i used room eq and go some decent results- !!!

it would take a pro like scott or ethan to really tell you whats up
but from the looks of it i'd be really happy with that- i'd actually be more than happy with that!


cojo post the songs up!


i'm moving into a bigger place so all the work i did, i had to take down! ahha

but my new place is a room all to me!!! so its gonna be a great adventure!

I think it looks ok, no really big holes in the spectra. But it looks like it roll of a bit early (just spekulating, better wait for the pro's).

What did you use to noise or a sine wave? What is the green line that is hi passed in one graph and low passed in the other?

[dim light]

xmostynx HA! Thanks a lot man - made me smile here. I think the low end part looks better than the high-end. I have KRK V4's here but these test where done with my cheaper KRK Rokit5. The roll off seems normal to me - these suckers don't travell too deep down in the sub low end but then again - maybe the low end looks weird?

Cojo the green line is actually blue! it has nothing to do with the test - I didn't figure that one out though... I can't explain in English - Det var nån skum grej typ man kunde ha subwoofer, eller flat etc - Vet i fan varför - jag kunde ändra den kurvan efter jag gjort testen av rummet.

Oh and I used a Sinus Wave...

Ethan, pro guys - Glenn guys where are you when I need you???

[dim light]

I'm going to add more bass traps - I have a bunch of them - I bought a long time ago - made by a pro guy. I will cover the wall behind the speakers - mix with absorbers and bass traps and I'm thinking of putting bass traps on the side walls to - First I need to treat the ceiling above the console. I will open up the corner traps a little to see what happens to the low end -

[dim light]

1/3 octave smoothing and the particle boards removed.

[xmostynx]

what are we doing? spending all this money on insulation and wood..


we should be spending all this money on strippers and jack!!!



graphs look good- gotta wait to see what the big guys come down with

I'm with you 100% -> I haven't recorded music in a month -

Can't you explain why my graph looks good haha - I feel sad looking at it! I can't interpret the crooked lines. I don't see such a big difference between the graphs without particle boards and the one with particle... Maybe I can install them again... I hate the looks as it is now!

[dim light]

Big guys where are you!?

[dim light]

Sorry for spamming the forum with graphs. I moved the speakers to the meterbridge - Now it looks much better right?

Yep!

Be careful not to move the mic an inch between messurments. I gave up my messuring after a while. I got different curves everytime!

[dim light]

I have the mic where I will sit and mix - ear height. I'm chocked - the problems in the mid/high-end disappeared. There is hope - I'll have to build stands that goes above the meterbridge - because I can't have the speakers on the meterbridge _ they vibrate and make funny sounds.

I have moved the mic a little - but I was able to reproduce the dips on all tests - the big difference was when I moved the speakers on to the meterbridge. Strange! I feel better now.

Dim,

Looks like to me you got it!!! You can add more traps but what you have now is GREAT.. How does it sound?'


Glenn

[xmostynx]

hey man those new graphs are sweeeeeeeeeeeeeet

now you have to give us a 360 view of the room..so clean it up! and lets see!!

Glenn I like how the room sound - When I had the speakers placed further away from the console - I got dips in the mid/high end - I had no idea speaker placement made such a big difference. One thing though that I forgot to mention. I put a rug over the console to tame the reflections from the console - When I removed the rug the graph looked like this;

I'm hoping that I can control some of the reflections by treating the ceiling - I'm thinking the sound bounch back and forth between the console and ceiling and if I can tame the ceiling some of those dips will go away. I will experiment until I have something good that I can live with. Of course speaker placement will play a big roll now when I know how much of a difference it makes just to move the speakers tiny steps forth and back etc.

Thanks!


xmostynx!

Of course man - I can take picture for you! Let me finish all the treatment before I post more studio shots.

Hi!

may i ask which program / measure mic / signal generator you used for this sweep? i'm using ethan winer's 1hz step test tones at the moment, but this takes always tiiimmmeee after a small movement...

Volker

[dim light]

Thanks for asking!

I'm using Room EQ Wizard - http://www.hometheatershack.com/foru...hread.php?t=19

You need to register to download...

I'm using the internal sound card on my laptop and I have a Mindprint DI-Port for preamp and a Shure SM81 mic.

[vls]

hey, thanks

my shure sm58 should reach (is this the right word in english?) for this measurement, i think, right? the main problems are the dips / peaks +/- 10dB..

I think it's better if you lend a small condenser mic but then again maybe a dynamic mic will work.

The best thing to do for the ceiling is build 4 to 6 2'x4' panels that are either 2" or 4" thick. Hang them from the ceiling down about 2". That will take care of those nasty reflections coming off the ceiling.

Hi - thanks a lot for the feedback!

I got lots of absorbers and bass traps - I'm thinking of using both bass traps and absorbers above the console - what do you think? The bass traps have a hard finish so they reflect sounds - would it be better to have the bass traps on the walls and the absorbers in the ceiling - should I pack them close to each other? Covering the same area as the size of the console? You can also see my custom made corner bass traps -

[Cojo]

Here is a link to the promised mix.

The Last Cluster.mp3

It's the first song entirlely tracked and mixed in my new treated room! Don't make fun of me now, at least I like the result! It's elektronic music so it may not please averybodys taste.

Does it sound ok to you?

[dim light]

I'm having fun @ you ha ha!

I think the mix is good - maybe a little too safe - almost a little boring. I think you could take the mix to a higher level just playing around with the width and also let some stuff pop out a little more. I dig the song -

The kick is sitting nice in the mix and the bass comes through clear and ready for sex.

I would add air around the hihat - the mix could open up when the hihat kicks in - make a stereo verb -

[xmostynx]

cojo cool tune!


you gotta do the whole 360 of your room as well.

dim where did you get those absorptionpanels on your ceiling? i dig those bigtime- how come your location says china dude? you in 2 places at once?

[dim light]

I'm eating rise man - that makes me 100% China!

The absorbers in the ceiling is made by a Swedish company called Svanå MiljöTeknik AB http://www.diffusor.com/

I have a hard time liking the grey color now when I'm all white. But I guess it will look alright when I'm making the studio more cosy. I'm looking for a floor lamp - the old 70ish looking one with flowers and some art. I want this room to be mint! You should feel at home when you visit me. Warm coffee in the cup and nice looks.

Thanks man for the kind words!

[Glenn Kuras]

I don't think you want to use those on the ceiling. Those are polys, which are great for the back wall if you sit no less then 8 feet from them. For the ceiling you really want broad band panels, 4" or 2" and space them 2" off the ceiling. You also want to cover the whole mix area above you.

Glenn

[dim light]

Hi!

Thanks.

The guys in the ceiling are absorbers - softis. Do you mean the other ones the bass traps?

When you say 2", 4" - can you please explain. I found a calculator for feets to m. But I'm not sure I understand 2", 4" and space them 2"

I'm hoping to save time - using the ones I already got.

I about 8 feets from the back wall so they should work. Sorry for all the questions - Hope you can clear things up - I'm probably going to start the build very soon so it would be helpful with some guidelines. To bad you don't live here - I have the coffee machine ready!
