EMES Virtual Rooms

During the process of acoustic research Emes has developed a unique Impulse Response database with more than 300 different Room-Models, all based on a very unique "virtual rendering" process.
All resulting Impulse Response Files are carefully processed, edited, categorized and finally stored as 192kHz/24Bit and resampled 44.1kHz/16 Bit Audio-Files (WAV and AIFF).
Available on a single CD (44.1kHz/16Bit) or double CD (192kHz/24Bit +44.1kHz/16Bit) -can be used with all Convolution Reverb Plug-Ins which support WAV and AIFF import - see list below!

Specialized CAD Programs which we use in our Monitoring developement process, allow us to construct "virtually" any geometric construction - from very small simple vector items to very large and complex structured Spline based architecture Models.

All rooms were designed as 3D "NET"-Models first, than each surface was given it's own set of acoustic coefficents like - Absorbtion, Reflection, Material (Weight, Grain, Damping, etc...).
In this given scenario we implement the Signal-Source and at last we define the Pick-Up configuration and there relative positioning.

With all these thausands of parameters, a calculation can somtimes take up to 5 hours for a single 8 Second Stereo Impuse Response-File (192kHz/24Bit)! (Dual Opteron PC)

There are some very nice benefits about virtually computed IR's compared to real recorded ones like:

quality - hear for yourself - download the free IR-Files below or listen to the "demo-tracks"
we eliminate nearly all sonic damages caused by a conventional electronic signal path!
(Impulse-generating, -amplification, -play back (normally a Speaker System),- pick up and -storage)
no disturbing backround noise
taking all sorts of Signal Source positions and Pick-up configurations!
- until we have found the best performing ones -
creating "Spaces" which do not yet exist!
modifying and tuning models to different acoustic behaviours

Each file has been categorized and is spezified in the CD- booklet (see below)
