Paradigm Simulation, Inc.

Audition is a sound design and editing system. The folks at Paradigm say: "Real time auditioning capability of Audition 1.0 enables the user to simultaneously listen to a sound file and modify it. This along with powerful tools like a 10 band graphic equalizer, loop definition tool, pitch shifter and resampler greatly enhance productivity for the professional sound designer. Audition also provides a frequency spectrum display so that the users can examine the frequency content of their sounds. All this and the support for editing across multiple Audition windows makes it a must-have tool."

IDEAS Sound Quality Engineering Now links to SDRC's Web site!
Studies have established that consumers identify sound as a major criteria in helping them to develop their impressions of the overall quality of a product. Sound quality has been an important issue in the automotive industry for decades, but is now also a growing concern for manufacturers of consumer appliances, office equipment, power tools, marine equipment, off-highway construction vehicles, farm equipment and other products. Achieving good sound quality is a much more sophisticated process than simply determining that a measured sound is "too loud." This process goes beyond basic sound level reduction to also include engineering the product to eliminate specific, objectionable sounds and yet retain appropriate, desirable sounds.

I-DEAS Sound Quality Engineering software enables you to measure and thoroughly analyze the audio "signatures" of a mechanical product in order to identify which features of a sound control its perceived character. Once the unacceptable features of these sounds have been identified, by employing quantitative metrics or qualitative jury listening studies, you can then set specific targets for a more desirable sound. Other I-DEAS products complement I-DEAS Sound Quality Engineering by enabling the engineer to use both simulation models and test data to develop modifications to improve the overall sound quality and to achieve the ultimate objective of designing the desired sound characteristics into the product.

IDEAS Vibro-Acoustics Now links to SDRC's Web site!
I-DEAS Vibro-Acoustics software allows you to predict how sound waves affect the structural performance of mechanical components and how vibrating structures generate noise. The module is fully integrated with I-DEAS Master Series software, thus enabling you to perform structural modeling, vibro-acoustic data preparation, structural and acoustic analysis, and dynamic testing through a single user interface.

Illustra Information Technologies 

Illustra makes an RDBMS, that, coupled with specialized "DataBlades," can function as a powerful media asset management system. Here's what the company says:

"The Illustra Server is the industry's first DBMS that efficiently handles alpha numeric, character, text, video, images, audio, and documents within a single repository [...] Illustra has introduced the idea of "DataBlade modules," which are object libraries that enable the general-purpose Illustra DBMS to handle the needs of a specific application. Loading a DataBlade module into Illustra is analogous to snapping a special-purpose blade into a craft knife to perform a specific function. A DataBlade module extends Illustra into a new data domain by defining new data types and functions to act on them. "

They have DataBlades for 2D & 3D spatial objects, images, OMF files (incl audio), text, time-series data, WWW information, and others. Check out their web site for more info...
