Help Please! Acouistic Treatment for Recording Studio

I'm after some acoustic room treatment advice for my Recording Studios in Brighton.
At ALT Recording Studios in Brighton our bank vault live room was very difficult to treat. It's square and tiled too so not ideal in its raw state. The problems were bass reflection and high frequency flutter.
I come from the prespective that the purpose of acoustic treatment is to produce the most even reverb decay time across all frequencies, minimising peaks and troughs in the low part of the frequency spectrum and also flutter echoes in the higher part of the frequency spectrum.

We've used Auralex tiles, traps and reflection and BASF ceiling tiles. My problem is we don't want a completely dead and dry room but also don't want any flutter echoes. Is this a trade off or is there anything I can do for a balance.

We've a few recording studio pictures on our website.

Any tips would be appreciated

The trick is balance between reflective and absorbing, you need both. If you reflective surfaces produce bad reflections, then cover them up with a better surface, build a studded wall and cover it with rough cut cedar planks or heavy paneling or some such thing that is still reflective.

Yep, there is no magic formula to figure out how much and what you will need to treat the room. You can figure somewhat by size and such how much or what will be needed. Especially if the room is square, then bass traps will be a must. But not to sompletely cut the reflection off but simply to control it as dB stated.

His suggestion of building out one or two walls is good as that will bring a major bit of control to the room.

Is this a good alternative to those GIK traps I've heard MM mention?

Jul 29, 2009 07:17 pm is a rad site for acoustic advice.

I started with an average garage. 4 parallel walls. To tame the flutter echo's I built 2 fake walls skewed at 12 degrees to eliminate parallel surfaces and added absorption (roxul 590 covered in cheap fabric) to the ceiling (my ceilings quite low) above where I would be recording main instruments. For bass absorption, I packed the cavities between the skewed and original walls with cheap insulation to absorb super low frequencies and inside the room I'm using 4 homemade 'Superchunk' bass traps placed in each corner, covered with a cheap orange fabric to absorb lows and low mids.

The non-parallel walls mean I don't have to add absorption to tame the echoes. Pretty ideal, and reflective!

I've added floor to ceiling panels covered in various meterials. Used Auralex tiles and BASF ceiling tiles. The outcome has been great. Thanks for the tips.
