DADEV : Digital Audio Development :

These products deals with binaural, space simulation, surround encoding and space localization.

Warning : all our products needs the DSPLIB to be installed : please download it here and follow the installation instructions.

The VRS is the only tool that can fully simulate a 16:16 environment with reverberation. All the surround possibilities can be created from its clear layout. But make no mistake, VRS sounds for the PRO recording.

08 January 2001 : Warning, with the new versions of the Creamware OS (v3.0 and +) the VSR takes much more DSP. VRS need at least 5 DSP to work.

Listen a small sample in .MP3 (700k). First we change the Room size (small ->large) then we move the left and right channels around the listener.

The Virtual Room Simulator combines a Surround module with 15 channels, 16 sound sources, an amazing surround reverberator, bass and treble extraction LFE & HFE), stereo monitoring, a 16 voices mixer in a fun and addictive layout. This tool is perfect for all multimedia or film designers who want to have an easy way to visualize their sound sources in space and move them in real time. The Virtual Room Simulator can be used by all the classical or live music composers to re-create the real acoustic of a room, you can place the instruments, the listener and in case of 5:1 mixing you can place the Speakers and listen everything in real time. The Virtual Room Simulator can be also a great deal for all the ones who want to mix in 3D 360° instead of using a classical 2D stereo mixer. With the VRS you can move any of your sound sources in space, turning around the listener, moving up, down left right and lsiten the result in real-time. Our brand new reverb simulate the acoustic of the room and change following the size of the room, its materials and its character.

The Virtual Room Simulator is a completely different tool. The reverberator inside is specially optimized for surround mixing and live space simulation. If you listen it (try the demo) this is self explaining. The Virtual Room Simulator sounds natural with all instruments. Piano, Drums. BUT you don't have the creativity of a Verb PRO. The Verb Series is designed to be a state of the art reverb, which does not means that it does sound realistic. Even if you can do something close to a realistic ambiance with a Verb PRO, you cannot simulate the distance between each instruments!

Complex modelization of the distance, size, and reflections in an attempt to fully simulate a large range of rooms types, from Cathedrals to Pubs ambience. Room size can be in the range of 2 to 400 square meters.
16 sound sources that can be moved in real time, corresponding to the 16 ins in a "classic mixer".
15 speakers that correspond to the speakers in a surround environment. For doing 5:1 you only need 5 speakers. You can simulate an environment with up to 15 speakers.
Stereo output simulation of the listened sound from the listened place.
powerful monitoring of all the source with or without reverb, monitoring the bass and treble channels, and the Stereo result from the listener's place.
Re-sizable room dimension. Rooms are square but can be changed in height and width.
16 vue-meters plus a gain for each surround speaker's output.
a unique 15 channels Reverberator to simulate the real reverb from the Room.
Doppler effect assignable to any of the 16 sound source to enable or disable this movement simulation effect. Works great on vehicles moves for example.
Room simulation center where you can move with the mouse or a controller any of the symbolized items all in real time.
Type of Wall, level reverb, size of room, early reflections amount, damping to re-create a realistic room modelization.
Timber button to create clear or Smooth rooms.
separate Ouput for the dry and reverb signal, mix dry, mix reverb to monitor the sum of all the surround channels, bass extraction and treble extraction channel with or without reverb.
Low pass and high pass filters for the treble and bass settings.
You can save your Sound source config, your Speakers, the Reverb parameters and you can also save all of them Globally with the ALL preset save.

The Option Panel

As requested by the Dolby Laboratories, we have programmed the LFE channel with a +10Db default enhancement and set to leave only the frequencies <10db. This channel was previously designed in 70mn movies to support additional subwoofers placed behind the movie screen.

There are 2 presets buttons. The POS button save the position surface speakers, sound sources and listener while the REV button set some preset room size and colors.

Preset : this button run the Preset list Loader where you can load and save your own presets, or factory ones.

Wall : Type of Wall. On the left the Walls have a metallic sound. More you turn this button on the Right more warm will be the sound reflections.

Ref : stand for Reflections. This button determine the number of early reflections and their presence. Early reflections are the reflections that are bouncing from the wall directly to the listener ears. They are bright and short.

Damp : is the Damping time. As you probably known, the highest frequencies are not sustained as much as the low ones. That a physical property of the sound in general. This button change the damping time. If you turn this button to the left, the highest freq are damped very quickly and the result will be very dark. If you turn the button on the right side, the highest frequencies will not be damped. The sound will sound smooth or metallic. But remember that a realistic room should damp the sound otherwise it will not sound natural.

Size : this button is complex and can dramatically change your room accoustics properties. This button change the room size form 2 meters up to 400 meters. The best is to play with it.

Color : this button simulate the atmosphere and temperature of the room. On the left it is hot, on the right cold. the sound changed very much a cold room will sound more bright. A hot room will sound more heavy.

MIX : this button change the level of the the reverb in the room. DO not add too much reverb, or only when you tune the reverb otherwise your sound will loose his punch and will sound wet and and dirty. If you want to have a very realistic ambiance turn it only and 35%. If you are in a cathedral you may try a 50% setup but if you add more, be careful to not destroy your mix.

For example the Full Orchestra 5:1 sample illustrate how to dispatch the different sections of an orchestra to simulate their position in the room space. Il you try to re-create an orchestra without using the VRS you'll have all the parts close to the listener and the result will be far from a realistic orchestra. If you play a midi file with an orchestra and connect each section of instruments to the VRS input, you'll have a more realistic result.

The Speakers are prepared for a 5:1 recording. So this preset will enable you to reproduce an orchestra in 5:1 & Stereo.

The Trio 5:1 preset does exactly the same for a group of 3 musicians or instruments.

The Surround 5:1 (and 6:1) are presets that set the Speakers at the right place. It is up to you to place the instruments where they need to be.

Of course these presets are not limited to Classical music. The Trio could record the group Police (3 musicians) as an example.

These presets are very useful for Jazz like performance as well, or any music played with natural instruments.
