For professional results, use these acoustic control devices in every stage of audio production.

  • The StudioTrap provides versatility and portability, enabling you to create the same sonic environment in any sized room, making them the most indispensable acoustic tool in your kit.
    The award-winning StudioTrap offers adjustable treble absorption & diffusion, 360 degree mid-bass trapping, and variable height in one convenient package. Improve accuracy and ambience in your mixes by arranging the StudioTraps into an AttackWall configuration, so you can hear the mix, not the room. Equally powerful in a recording setup when set up into a QuickSoundField, the mic will hear subtle details and harmonics that were previously buried under the room self-noise.
    StudioTraps are sold and shipped in pairs

  • SubTrap

    From $699

    Bass Refined

    You keep your subwoofer's volume turned down and the crossover set low so it can “support” the bottom end without drowning out the music. But... you know you can do better. The SubTrap absorbs excess bass (the bad, muddy bass) and decouples your subwoofer from the floor and elevates it out of the vertical mode stimulation zone. While increasing bass extension and punch, the SubTrap also gets rid of the dreaded "one note bass". Utilizing our patented Isothermal technology to boost the low bass absorption, the ASC SubTrap should be the foundation of your acoustic control plan. It's much more than a simple vibration isolation stand... now you can "raise" your subwoofer to its full performance potential. Simply place your subwoofer atop the SubTrap. You'll instantly improve sonic detail, changing “fuzzy” playback into a richly detailed picture by lowering the running noise floor of the room in the all-important low bass range. From there, build your musical experience with rich harmonics and a lush, and immersive soundstage. You'll hear musical bass lines you never knew existed!

  • AttackWall

    From $5,112

    Work in Perfectly Clear Sonic Space... Anywhere

    The AttackWall is a free standing workstation that consistently provides a reliable, repeatable, and accurate sonic space in which to track, mix, and master, regardless of room acoustics or speaker system. The AttackWall is the most amazing sounding space you'll ever work in, and truly redefines world class mixing environments. The acronym A.T.T.A.C.—All TubeTrap Acoustic Control. Art Noxon added the ‘K’, for Kit and recording engineers who mixed on these early systems.
    Applications:
    • Mixing
    • Tracking
    • Editing
    • Mastering
    • Beat Making
    • Post Production
    • Sound Design

     
  • QuickSoundField

    From $2,556
    The QuickSoundField is a near field recording environment that allows you get the most sound, at the highest quality, into your mics by using a configuration of StudioTraps. The QSF can transform the center of any ordinary untreated 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 uses the principles of "sound fusion" to maximize the quality - and quantity - of sound reaching your mics. The QSF encircles 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.
  • ASC SoundPlanks are the perfect companion to ASC TubeTraps for complete control of the acoustics in your room.  After the bass range is under control, the SoundPlanks further improve imaging and flutter echo without taking up any floor space.

  • WallDamp

    From $44
    WallDamp is a component of ASC's IsoWall System, used to construct walls & ceilings that reduce sound transmission by 20dB or greater compared to standard interior walls. Combining vibrational damping with classic resilient channel decoupling makes our wall system among 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 to prevent excessive low frequency reverberation.

  • ASC's PanelTrap is a combination mid/treble absorber diffuser that also traps bass when mounted across a corner. It's a budget friendly basstrap that is easy to install and easy to look at. Equally suitable for recording studio, hifi, and home theater use, a full PanelTrap system can transform your room from an intolerable echo chamber to a pleasant space for work or play. Systems include mounting rails for flat or corner mounting. Units are 16" wide and typical length of each section is 60". Priced at approximately $40 per linear foot of coverage.
  • The ASC Acoustic Test Signal

    Explore the musical intelligibility and the sonic image-ability of your audio system 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. Play the MATT test 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. How fast is your room? Most audiophiles know how loud they can play their room before it begins to break up. 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.

  • Professional Recording In-Line Mufflers

    Recording studios and rooms with quiet requirements need dampened HVAC supply and return ducting. ASC designs and manufactures in-line mufflers, noise-reducing outlet diffusers, and duct baffle inserts. Most residential and commercial HVAC equipment creates too much noise for use in recording studios. We build specialty mufflers that combine built-in bass traps with standard treble range absorbing panels. Our solutions not only deliver air into rooms silently but also reduce the acoustic crosstalk between rooms through the HVAC ducts.
  • MixClouds offer studios the broadband acoustic control and noise reduction they need to control flutter while mixing tracks. This is more than an easy to hang flat panel product. ASC includes the MixCloud as part of an overall custom acoustic plan for your studio, so there’s no guesswork.
  • ASC's SoundPanel is built to interior design standards, it features bevel cut face, crisp corners, and smooth finish. They come in a wide variety of beautiful fabrics and is trimmed out by a paintable white picture frame. The SoundPanel is completely finished on all sides, including the back.
