    Help deciding bass trap size and density

    Hello all, After going through a lot of expert advise and reading articles here and of course the available material, this is what I have decided for treating my room - 1. Broadband Panels for early reflection, rear wall and where ever need - 64kg/m3 rockwool, 4" thick with a 2" airgap. 2...

    Solved Comparing the two shapes of velocity based absorbers in corners

    Ok found this - Absorption is generally at it's minimum when the boundary of the absorber is perpendicular to the incoming wave. At other angles the path through the absorber is longer.

    Solved Comparing the two shapes of velocity based absorbers in corners

    Hi everyone, I was really interested in doing a comparitive study of the two types of velocity based corner trap designs we see all the time - the triangular v/s cube shaped. I did not find a detailed comparison anywhere and I understand that what is needed and works best is subject to the...

    Can someone comment on my first attempt at acoustics?

    Aaah thats a good idea! Will redo the kind of treatment in the drawing and post it. thanks mjbphotos

    Can someone comment on my first attempt at acoustics?

    Hey thanks for that calculator! And for how I can compare those figures. That should come handy. Will do this today. Yes atleast a start. :) will have to give time to finalize the panel placements through listening, mixing. But when you say the treatment is uneven, are you referring to not...

    Can someone comment on my first attempt at acoustics?

    Hello everyone, Found this this cool online 3d sketcher in which I made a plan to treat my studio. Here is the link to my first attempt at treating a room and making a 3D interactive sketch - Roomle 3D floorplanner for your design ideas Also attaching some snapshots I took just in case. Do...

    Acoustic Foam types and their densities?

    Hey I am getting a good deal on the 4" slabs. 2$/slab. Although I was wondering if the solid looking boards on the 2nd page are any good for absorbing any spectrum at all? They look like the Fabrock series. And look easy to handle/install without a frame. Was wondering myself if I should get...

    Acoustic Foam types and their densities?

    keith.rogers was indeed waiting for the seller to send me a data sheet of whatever he stocks. I have attached it above if you can spare some time to advice. Will definitely decouple the panels atleast 2 inches from the wall, or more if mounting doesn't get too difficult. mixsit Thought if I...

    Acoustic Foam types and their densities?

    Hey these are the kind of sheets a local rockwool dealer presented me with. The only difference I see in the first 2 types of rockwool is that the 2nd can be purchased with a coating/ face, even though he said that its preferred for wall partitions/ceilings more that absorption inside a room...

    Acoustic Foam types and their densities?

    mjbphotos ok so no on the foam. Rockwool even turns out to be cost efficient here and more importantly, it seems to be a far better absorber. Most of the rockwool batts i find are 1m x 0.6m, 2in thick. Will check out Roxul. But the reason I wanted to frame them is so that I can leave an airgap...

    Acoustic Foam types and their densities?

    Hey thanks a lot for the replies! Keithrogers I now feel sceptical about using foam as an absorber after reading how much less a foam sheet does for absorption than advertised. Is rockwool a better choice. Get a feeling that foam sheets can only be used for very slight alterations after...

    Acoustic Foam types and their densities?

    Hello All, I landed on this great forum sometime ago when I finally decided to treat my room with better acoustics and this place has been extremely resourceful. So I went ahead and made the walls soundproof as much as my budget could allow and want to treat the walls now the best I can. I...

    question about the pan law

    Hello everyone, just wanted to know what pan law you guys are using for mixing. Is there a preferred pan law for music mixing? I admit of having a less than suitable environment to make out pans and levels precisely and can depend on meters only so much. (heavily rely on headphones) From what I...

    Levels and metering - analog v/s digital

    Hello Farview, been trying out all the suggestions in the mix. Though my concern is that the individual track levels and peaks are fine, around the -18db mark, with drums peaking at -10db. Its the master bus that goes upto -3, -6db when all instruments are playing. Is that too hot even for the...

    Levels and metering - analog v/s digital

    thats what i was thinking.. but you have a good reason to record audio too. And def gonna be much more careful with gain and faders now.

    Levels and metering - analog v/s digital

    Well more than recording, i sequence midi using samplers/vsts, which have 16 outs sometimes like the maschine. When these are enabled, 16 buses are created in the DAW. Now whatever you have sequenced in the vst sampler can be routed to these DAW buses and they can be further routed etc etc...

    Levels and metering - analog v/s digital

    Oh yes the input trim in Cubase when using a maschine sampler as a vst. Neat! But what about cases when i am just using the sampler with its software, without a DAW? Should I pull down the faders to -18, or do I have been auditioning my performances on pads and controllers to see my peaks and...

    Levels and metering - analog v/s digital

    Cool.. But coming back to the dbfs topic and working entirely in the digital domain - since there is no such thing as input gain when working just with a laptop and a sampler, should I just pull down the sample level to read -18db on a meter? Because the only 'level' control I have before this...

    Levels and metering - analog v/s digital

    So as soon as anything goes in the mixer the first thing that happens is A to D, irrespective of anything? A to D right after the in to the mixer, D to A right before the outs to the speakers? So are the EQs on the mixer also Eq'ing a digital signal, since you say A to D happens right after the...

    Levels and metering - analog v/s digital

    true but when there is no daw/computer and its just the instrument in the mixer(analog in), mixer outputting to speakers(analog out). I dont see anything digital here. So how does a dbfs meter on a mixer function in this case? Thanks again!
