how do you put acutes and graves etc on letters?
Yóú úsé a Spánísh kéybóárd drívér! :) You can also the ALT-key combinations, but I never bothered learning them: Much easier to load a Spanish keyboard driver (or one for another language). I actually have several keyboard drivers loaded under Windows Vista, and I can switch between them at any time. You just have to remember which keys change function! :shock: - Stuart -
on a windows machine, simply press (CTRL plus) the acute/grave you want and then press the letter itself. It's like my full name is Róman. I press ' first and then the o. Sometimes you need CTRL+' itsa simple :mrgreen: BTW, this really is a great build :yahoo:

Absolutely nothing to apologize for. You did it out if respect. Andre
andre, ah...ok. canadian not french. i have to admit that my lack of georaphy led me to the assumption ontario might be in the "french part" of canada. thank wikipedia! i wasn't too wrong. anyway.I'll keep it in mind. funny. on my keyboard there's a button left besides backspace with an ´and an `. you simply press it before the letter you want. but i guess this is managed by your keyboard driver (windows) or language settings (mac) as stuart already mentioned. anyway to that, too. =) nice to have you all around looking into my thread. :thu: and a double nice to see that there's a life beyond studio design. i love slightly off topic excursions. that said: anyone out there following the world cup? watch out for the match ghana vs germany on 23rd of june. i will be there =) (nope. I'm no soccer nerd. it's jobwise) just thinking 'bout how to attract attention. maybe i should wave with a giantic JLS banner...? wish you all a nice weekend, carsten p.s.: pics - or it didn't happen...stuart, i swear this IS happening

Ontario, the province I live in, does not have an official language. There several parts of Ontario where french is the common language. That is street signs, schools, etc use french. Andre
back to business... here is a before and after comparison. topic: slot resonator @ rear wall to tame a 120 hz boost @ listening position(see a couple of posts before) the pink one is the original graph (without slot resonator) the blue one represents the new measurement.
Image not preserved: before vs after slot resonator rear wall.jpg
box depth of slot resonator: 95mm - 125mm slat depth: 19mm slot width: 2,5mm (width of my circular plunge saw blade) slat width: 205mm (all slats have the same width) center frq @ 110mm: 120,1 hz min frq @ 125mm: 112,7hz max freq @ 95mm: 129,2 hz 5cm rockwool behind slats.
Image not preserved: IMG_0041.jpg
this slot resonator was meant as a "tuned" absorber with a center freq @ 120hz. you can see on the graph (46 hz - 275 hz / octave below and above center frq) that it really works in that range. but the improvement is very small imho (~ 3db). measurement made with roomeqwizard. no trace adjustments. peak @ target freq was 12db above 75db (calibrated) is now ~ 9db i should mention that my speakers still have a bass boost caused by the soffits. i had no time to build barefoots lowshelf... any comments? should i post the waterfalls or rt60 graphs? greetings, carsten
hellllllllloooooh dear ladies & gents! still alive. still building. and now i can finally see some light at the end of the tunnel =) just a short one. just some piccis. enjoy :D greetings to this wonderful place! carsten

carsten_d, You do excellent work, great attention to the detail, I know personally how difficult it can be fabricating wood product on site but you make it look easy. +1!
I don't have words....that is really some beautiful work, Carsten... I wonder, what sort of illumination do you use? Congratulations, you certainly deserve them :mrgreen: Sono
Congratulations on great work! Andre
wow :oops: thanks dear friends! :idea: illumination? right now I'm struggling about this topic... halogen bulbs will become very hot. LED is still very expensive. ordinary light bulbs die out. hmmm. I'll order a couple of LED spots and test if they're bright enough. I'll mainly use indirect light (build under or behind absorbers or in special cases, etc...that's why I can't or won't use halogen bulbs). and I don't like the typical overhead lights. apart from that do I really want light with minimum 5000K. all the best, carsten
Please let us know ur impressions :)
Hi Carsten I used only LED Lights in my studio, and LED is ok. I have to search for LED flood bulbs, and not the spots. There are also energy sver bulbs for GU10 socket out there. But i prefer LED lights. I payed about 10,- for one flood bulb. But be shure you oreder high voltage bulbs not the 12V system. With 12V i had only problems, so i replaced them with 230V. Another experience is, that it`s better to use more 1W bulbs than these high power LED`s, because the expensive high power LED (cres...) start to strobe after a few weeks. the cheeper 1W LED`S are far better, from my experience. cheers Mika
:lol: sounds good! I ordered this afternoon 10 GU10 sockets and 10 cheapo LED spots (230V) from Reichelt...just for trial & error. I guess this is exactly what you were talking 'bout. cool! thanks a lot mika! and btw: don't tell me that my build might be sexier than yours!!! no way!!!! good night and all the best, carsten
i tryed all of the LED stuff. The best i could find was the conrad flood LED`s Spots are a little to dark for my taste, but you will find out, when your bulbs arrive. cheers Mika
Hey Carsten, This looks absolutely amazing ! Best of luck with the rest of your build - looking forward to see it finished !
dear companions, I'm really glad to tell you that I'm almost finished! a few things need to be done, I guess a few things will never be done =) time to start learning! the ctrl room sounds pretty good though there are a few problem spots - frequency wise. I guess the room is too small and I am too unexperienced to get it right from the beginning. anyway, this is more than an upgrade to my former listening situation. and that is GOOD!

the rec room sounds live. "big" for a small room with nearly 18m². now it's time to experiment with absorption. my intention was to start with minimal treatment (fixed corner absorbers and slat panels, a moveable poly and 2 moveable broadband absorbers) and expand the treatment by testing and recording and testing and so on. to get a glimpse of all this acoustic stuff I'm reading and reading about...

I started this project 2 years and one month ago by renting this facility.that was in november 2008. construction started in the middle of march 2009. main frame, electric and audio cabling and ventlation system was done a good month later. 1st layer gyprock started on 21st of april 2009. 2nd layer gyprock was done on 24th of may 2009. on 7th of july I thought I only had to build some doors and start with the ctrl room... well wood for the doors arrived on 25th of july. 1st door hung on 3rd of august 2009 (unpainted, just a test to see if I were on the right track) I finished the door and window era on 20th of september. still soooooo many things to do =( and I didn't know what...and how... exactly one year after the first wood delivery the second came: 12th of march 2010 I started with the ctrl room. 8th of june I was finished with the main work in the ctrl room but still needed to build 33 frames for the fabric...just for the ctrl room... 12th - 14th of august I built the diffusor for the ctrl rooms backwall. on 20th of september 2010 I nailed the last cloth frame on its place in the recording room. after that I built a poly, struggled with the lighting, built a seat bench for the ctrl room's backwall, built a rack for the ctrl room, set up a a small workshop in an extra room right in front of my studio and loads of small things I wasn't aware of...(a door bell for example) jesus! such a long long time. just a reminder for myself: You have done this all by yourself! two hands, two arms, two feets, one head and I was a couple of months on tour... 1st thing I want to mention is: Andre's (AVare) signature: Good studio building is 90% design and 10% construction it's true! I will never ever start such a project without knowing how it all should look in the end! just an example: if you're tight on budget (like I am) but you're willing to spend money on good quality audio cables don't think (unless you REALLY KNOW where your patchbays will be) that you might save some money by shorten these high price cables to it's minimum...this will end in PITA plus a potential degrade of quality... this happened to me. I thought that I don't want to build soffits for my speakers. and I wasn't sure in which direction I will layout the ctrl room. all my audio cables ended in a corner... unluckily in a corner where now a soffit is...I had to crawl under the soffit with a soldering iron to extend nearly all cables except for the good ones (the guy who sold me the mogami cables said to me NOT to buy 20 meters when I need 20 meters...so I bought 25. payed for 22...phew) this is dumb! now I know =) some things I want to change in case I'm doing this again: I will never ever build sth like this on the xth floor! never! underneath my feet will never ever be anything except concrete over ground/soil! I will never ever design a ctrl room without a room in room construction (except when I'm in the woods - but i guess even there I will do it. the silence in the recording room (room in room) is sooooo pleasant. when I close the doors and the silence starts to encircle me I immediately come down. this is so beautiful!) next time I will definitely consult pros when it's time to start planning the HVAC/Ventilation, electricity, audio wiring, eventually also alighting expert and a structural engineer. yes. nearly everything. It's not that I want them to do this for me (unless I have enough money) it's more like an assistance (though I'm not sure if this is common practice). I want sth I can RELY on. I think there must be a couple of other things but I'm a bit tired thinking about all this stuff... I'm done :D and yesterday I earned the first money in/with MY studio I'm happy as hell! Oh...i forgot one thing: the doors! they are all warped :? the worst about nearly 8mm the least about 2mm next thing, when I have some more money and time, is to install real strong latches (I guess it was Phybeau who had a link...not sure right now) magnets are a fine and quick solution but when it's getting loud in the rec room the doors need to be CLOSED. all seals need to be under pressure. anyway. good enough for the moment... a few piccis how it looks like right now (need to make better piccis urgently!) (still need to build an adequate desk in the ctrl room...) oh, my studio has a new name: abteilung m (need to make a logo...sigh...need this...need that...will this end someday? ;)

cheers, carsten
congrats! very nice work and it should be fun to see you finalize the bits to tune and of course plan your next one :)
thank you, glenn!

Hey carsten. I love the look of your studio! Do you have some final measurmetns of the room? Some ETC and Waterfall plots for get a feel of the room ? I have a friend in Berlin who ist a SAE bachelor Student there. Can i sent him to you, to be my ears, for checking your room? ;-) cheers Mika
glad to see you've finally made it carsten - well done mate. :thu:
hey mika, cool! would be nice to meet your "ears" =) I pm-ed you my email. oh :) thank you John! and thank you for this wonderful forum! as soon as I can I will contribute an adequate amount to this informative and great place!! unfortunately i'm sitting here empty-handed =( here are some screenshots. measured with REW version 5. Mic @ listeningposition. height: 122cm Mic: behringer ECM 8000 I used the left speaker only. speakers are Adam Anf 10. powered with a "modified" Alesis Ra 300 (I desoldered the crappy pots and soldered instead new and selected 1% metalfilm resistors in the gain stage of the amp. this fixes the output of the amp and also fixes the balance problem between the left and right output. i wasn't able to get the same out of the left output and the right one. the pots were incremental but not equal. I tested with a 1khz sinetone and measured the output voltage of each channel with a voltage meter. the readings were always different. for example: left was eg 900mv right was 700mv. the next step on the right pot was 1200mv...) I still haven't build barefoots DIY Filter to fix the bass boost due to soffit mounting... Oh, one thing I also tested was the TL between rec room and ctrl room. don't know if this might be a scientific way to do this... here's how: while taking measurements in the rec room (I was in the ctrl room with doors closed) I noticed that there are some frequencies way louder than others. so I took the mic into the ctrl and positioned it @ the listening position. REW played the sweep in the rec room and measured in the ctrl room. now I had a curve from the ctrl room with a source from the rec room. the last reading in the rec room was my reference curve. I simply took the reading from the ctrl room and subtracted it @ each STC frequency from the reference reading from the rec room. now it turned out that @ 125 HZ (TL:38,8db), 200 Hz (TL:36,7db) and 250 Hz (TL:32,4db) the TL was far under the expected. whereas @ all other frequencies the Tl was between 48,8db to 67,3db. there is a site where you can calculate the STC (-> http://www.diracdelta.co.uk/science/sou ... ource.html) the STC here is 47... should be 54 (http://www.sae.edu/reference_material/a ... 0Chart.htm) I haven't used 16mm plasterboard. mine are 12,5mm. I haven't used laminated glas. mine are the not recommended insulated float glass ones with two panes and a special gas inbetween. I found 'em on the yard here and thought that if they are really that worse I can change it whenever I want and have the money to do so... I noticed that the rack I built on the wall to the rec room seems to resonate at or boosts a special frequency (need to figure out that) anyway. I'm glad and still learning:) cheers, carsten here we go:
