Professional Recording Studios

ASC takes a comprehensive approach when working with you on your Professional Recording Studio. Whether you are just trying to fix one problematic sound in the room or have us join your design/build team, we're on board to help you get your recording studio sounding right the first time and as quick as possible. 

When it comes to your studio acoustic project, you get one shot to get it right.  Almost never is there enough money, time and energy left over after a studio project so that you can redo some non-working part of a recently finished project.  That means when we're involved we know we have to get it right the first time...

In the early days, ASC sold products to engineers who were trying to fix their problems, and we still do.  But, after 30 some years of this, we've learned a lot about how to fix a studio and even more important, what not to do when building a studio.  When we join in at the beginning of a studio project, we're not fixing problems.  We're making sure there are no problems to fix.

ASC is the pioneer and leader in factory-built modular professional recording studio acoustics. But it was our clients, those early recording engineers who blazed the trail.  They had a problem to fix and knew what they needed and where they needed it.  We designed, voiced and built the products they needed.  And one of the requirements always was to get it done quick.  
  Studio Recording Acoustic Products

In the early days we were suspending TubeTraps from the ceiling and stacking them along the walls and in the corners to deal with vertical and horizontal acoustic energy reflections, reverb/mode decay rates and stimulating diffusion. 

Then we developed half-round and quarter-round TubeTraps, studio-grade acoustics that could be mounted on the surface of walls, corners, and ceilings instead of stacking and hanging round cylinders.  This evolution in our product line wasn't our idea, it was what we could do in response once again to our clients, recording engineers who wanted more floor space and a more architectural studio look.  We kept the upper treble diffusing panel in this new line of surface mounted traps but it was no longer adjustable as it was with the full-round TubeTrap. 

Then the third stage of our product line that services the pro audio industry took place.  Because of the "Lego" aspect of TubeTraps, recording engineers kept fooling around with them, stacking them and moving the stacks around in open space, following their ears until the AttackWall and the QuickSoundField were developed.  We entered the realm of free-standing studio acoustics and developed the StudioTrap.  We weren't too far away from studio goboes but a lot more focused on what the engineer's ear hears and what the microphone picks up.  With these professional acoustic systems, Awall for mixing and the QSF for tracking, a functioning professional studio can be set up in a matter of hours.

Acoustic Sound Room Products

Along with manufacturing and sales of acoustic products, ASC offers a no-charge initial consultation to help customers select and use our products effectively. A more in-depth design service complete with an acoustical engineering report is also available for a nominal fee. The fee is later applied to your purchase.

Just fax, mail or attach to an email a dimensioned sketch or plans along with a bunch of photos of the room/space you are planning to work on and we'll open up your file and get ready to work on it.  Consulting is based on billable hourly time.  We'll usually include ASC products in the development of your studio project and some of the consulting fees will be used towards the products.  We can also start with a minimal acoustic treatment, and design an upgrade path for you to work up to, as time and budget allows.  Make one call:  800 ASC TUBE (272-8823) to get started.  

Custom Acoustic Products

ASC is more than a TubeTrap factory, it includes an engineering design and product development team.  We develop and make specialty acoustic devices that do specialized acoustic work.  We design and manufacture acoustic products that address your specific acoustic requirements. Customized products can range from a slight modification of an existing ASC product to a start-from-scratch innovation.  Most of our new products come from the work that went into these custom projects.   

We've worked on and fixed so many acoustic spaces, such as recording studios, performance halls, churches and listening rooms that we have learned how to design spaces that work right the first time.  We work with owners and product developers to evolve the acoustic side of their projects.  We work with engineers, architects and designers to come up with the acoustic solution that works right the first time, looks great and lasts a lifetime.

Technologies Used

Acoustic Bass Traps

• TubeTrap - Bass Traps

The physics behind the TubeTrap is based on the characteristics of an acoustic RC circuit which is similar to that of the more familiar electronic RC circuit.  Although electronic resistors and capacitors are fairly small, in the world of bass range acoustics the size of acoustic resistors and capacitors are fairly large, the size of TubeTraps.   

The acoustic capacitor (C) is the air chamber inside the TubeTrap. The bigger it is, the more efficient the TubeTrap becomes in the lower frequency range.  We've recently converted the adiabatic air chamber of the standard TubeTrap into an isothermal air chambers in our newer IsoThermal TubeTrap (patent pending) model which literally doubles the low frequency absorbing power below 60 Hz. 

The acoustic resistance (R) belongs to the surface of the TubeTrap.  In order to have efficient transfer of energy out of the acoustic wave and into the resistive surface of the TubeTrap the surface impedance (Z) of the TubeTrap is matched or equal to the radiation impedance of sound in air, 406 Rayl. The resistance (R) of the TubeTrap is Z/A, the impedance divided by the surface area (A) of the TubeTrap.   Because of this combined with the fact that the back side of the TubeTrap is just as absorbing and the front side, the efficiency of the TubeTrap, similar to Harry Olsen's Functional Sound Absorber (1953, RCA Labs), ranges as high as 170%.  

• Adjustable Diffusion Built-in

Acoustic Room ProductsAnother unique feature of the TubeTrap is its built-in upper treble range sound diffuser.  Just below the surface in the front half of each TubeTrap is suspended plastic sheet that has the right weight and hole pattern to become an acoustic crossover.  It back scatters the upper treble and lets the bass pass right through.  The chrome dot in the edge of the TubeTrap endcap marks the center of the treble reflecting side.  

From the circuit viewpoint this crossover sheet acts like an acoustic choke (L) or inductor that is sized, ported and mass loaded to back scatter the upper treble range, above 600 Hz while at the same time lets the bass pass right through.  The TubeTrap is typically located in a certain position to absorb bass and then rotated to bring the treble diffusing panel into position as well, either set forward to scatter treble back into the room or to the back so as to absorb treble from the room.  Usually the treble diffuser is position to scatter the treble back into the room, creating a low level "ambience" effect.   

What makes the TubeTrap so popular?  Unlike, 'built-in' or wall mounted acoustic products the TubeTraps stand in front of the wall, they are not attached and can be moved around with ease.  People stack them into tall cylinders and placed in the corners of the room and along the walls of the room.  By the trial and error process people learn to acoustically erase the natural acoustic signature of the room, and replace it with the acoustic signature of the TubeTrap setup. 

TubeTraps are 'modular' acoustic devices that can be arranged in a seeming endless arrays.  They bring to those working with room acoustics the ability to acoustically reshape the room acoustic without picking up a hammer.

Subwoofer Woofer
Subwoofers deliver punch and thump from the LF track 
which usually ends up shaking the whole house.
  Woofers pump up the bass, while the room folds it right back, trading out dynamics for modes and standing waves.   Mids and Tweets polish the treble but most rooms are too bright and quickly overflow with harsh backsplash.
