    The Quick Sound Field is a near field recording environment that allows you get the most sound you can into your mics. The QSF as we call it can transform the center of an ordinary room into a lush recording space. It works great for all types of recordings, from tracking drums and vocals in wide open spaces to close miking guitar amps in close quarters. The QSF lets you get more sound into your mics. StudioTraps setup around the mic and talent create a recording space that is sonically decoupled from the room acoustics. Inside the QSF the sonic quality remains consistent from one setup to another without the need for studio notes. The talent is free to move around while recording and no one can hear the change in position. Most important is that what the talent hears inside the QSF is what they hear in the control room.

    Tired of floor-ceiling reflections and vertical resonant modes wreaking havoc with your monitor response? You can achieve broadband acoustic improvement using this specially adapted set of TubeTraps designed just for monitors.
    The MonitorStand is a broadband absorptive product, built without diffusers unless they are specifically requested. Our mentality is: "launch a clean wave, and half the acoustic battle is won."  The MonitorStand arrangement is a quintessential demonstration of this concept.

  • Half Round TubeTrap Isothermal

    The Half Round TubeTrap is a versatile evolution of the TubeTrap, allowing the same sound-busting power of the TubeTrap to be wall or ceiling mounted. The unique and effective design of Half Round TubeTraps combine broadband absorption, diffusion, and directional control of sound reflections to reduce noise levels while maintaining room brightness and enhancing image resolution. This design approach results in compact and modular units that can be placed in patterns on walls, ceilings, and in corners of any room. The TubeTrap is the foremost corner loaded bass trap in the audio industry. It was only natural that ASC would adapt the same technology to fit flush into corners, walls and ceilings. Art Noxon, inventor of the revered TubeTrap, went to work on the physics and before long, the Fractional TubeTrap was born. Used mainly by audiophiles and recording engineers, the Fractional TubeTrap is used to fine tune room acoustics. Built-in diffusive wide angle treble backscattering above 400Hz and absorption down to 55Hz maintain room brightness and enhances detail and articulation as well as image resolution. ASC custom builds your Fractional just the way you want it, because no two rooms are exactly alike.

    All Half Round TubeTraps are made with our Patented ISOTHERMAL technology

    #18 out of the 20 best drum sounds of all time

    Because of what Bruce came up with, the sound that was created was recently voted #18 out of the 20 best drum sounds of all time! Here is an excerpt:
    18. Billie Jean: Michael Jackson (1983) from the album “Thriller” Whilst other artists in the early 80s seemed to be going bigger, flashier, more processed and more extravagant with their drum sound, for an artist to release something so natural and minimal was a real gamble. Producer Quincy Jones wanted to cut the 29-second introduction (which was the longest one ever created at the time) and yet it is undoubtedly the drum sound that has since gone on to define the record, and all within the first few beats. Jones had earlier instructed engineer Bruce Swedien to create a drum sound no one had heard before. Read full article here

  • WallDamp

    With the Walldamp Iso-Wall System, you get walls & ceilings that reduce sound transmission by 20dB or greater compared to standard interior walls. That is more than quadruple the perceived sound volume reduction, which is what makes our wall system the highest available using standard single-stud construction. Internally, the walls are tempered to move with the air pressure of bass frequencies. Where a rigid wall would shudder at high volumes (similar to the distortion in an overdriven speaker) and raise the noise floor of the room considerably, an IsoWall will "bend" with the pressure and absorb the sub bass sound wave while allowing the bass waves to reverberate cleanly.

  • When floor real estate is precious, the ASC AcousticSoffit is the answer to your bass trapping, treble control, and diffusion needs.  By utilizing a large air cavity surrounded by a flow-resistive membrane made from porous absorptive material, the AcousticSoffit provides the benefits of flat wall panels and large-diameter free standing TubeTraps in a tidy, easy-to-install package. This is a custom engineered product, sized specifically to integrate into your room and make it sound--and look--its best.  Our standard size unit protrudes 16" from the wall and 10" down from the ceiling.  This works extremely well for most rooms, and is roughly equivalent to installing 16" TubeTraps along the entire length of your wall/ceiling intersection! ASC engineering has taken care of the mathematics to ensure that your room remains sonically controlled without becoming over-deadened.  You will hear much more sonic detail from your speakers, from fine string work in orchestral passages to crystal-clear movie dialog and singers.  True broadband control can be yours as musical bass lines emerge and sparkling ambience surrounds you. The ASC AcousticSoffit is a one-stop acoustic treatment that in many cases will be all you need.

    Sound waves emanate from a loudspeaker in much the same way as a beam of light radiates from its source. And, like the beam of light, will be reflected off nearby surfaces. These reflections can be beneficial or deleterious depending upon their intensity and time of arrival, in relation to the direct sound from the speaker. Reflections arriving too soon (early reflections) after the direct sound, confuse the ear/brain, creating chaos in the image, defocusing and confusing the three dimensional recreation we strive for.

    MATT  - The ASC Acoustic Test Signal

    ....play it first over headphones and then in your room.  You hear a scale of rapid tone bursts that any HiFi system should be able to reproduce.  Your system could but it can't because the room keeps getting in the way.  Then concentrate on the sound stage.  It's a mono signal and the image should stay stage center, tight and focused.  But it doesn't. This test is a rapid gated slow sine sweep.  It demonstrates the musical clarity vs frequency of the HiFi system in your room.  In some ranges of sound you will hear strong rapid dynamic sound level changes while in other ranges the tone bursts blur together in reverberant chaos.  You can also hear the more familiar peaks and valleys of your room.  Then play it again but this time close your eyes and concentrate on the sound stage of this perfectly mono signal.  In some tone ranges the image stays put; stage center, small and tight, where it belongs.  But the next tone range sees the image lose focus and fluff up into a ball of fog. And yet another sees the image up and wander off, flying around the sound stage like Peter Pan. The objective of performing the MATT test in your listening room is to determine where you might move your speakers, listening position, and/or where to add acoustic treatment to your room to obtain the highest quality sound possible from the components in your listening environment. To explore the musical intelligibility and the sonic image-ability of your audio system... How fast is your room? Most audiophiles know how loud they can play their room before it begins to breakup. Even the speakers have a breakup threshold, above which we begin to hear cone breakup and box buzz. The MATT test is an easy way to ring out your room without risking doing damage to structure or gear due to sustained power at one frequency. At lower sound levels it checks out the room acoustic part of your listening experience, sorting out clear dynamic bandwidths from blurred bandwidths.
