The advantages of modeled IRs


microphone recorded IRs

1 - Unparalleled speed

Find your best room in seconds

Just playing back your IRs from a standard convolution reverb may require a substantial amount of time.

With Dspatial Reality you’re able to find your best room almost instantly. With its cunning modeling structure, you can modify the specific parameters that each individual project calls for. If you wish, you could also save your adjustments as a preset and use it as a starting point for your other projects.

2 - Flexibility

Change size, shape and surfaces*

Model the acoustic and physical properties of your room on the fly. Adjust the size, shape and surfaces included within your desired environment and manipulateany acoustic parameter, like the amount of glass, absorbers or diffusers present. To make it even easier for you, we’ve taken the liberty of incorporating a relevant combination of options to choose from. And once you modify them,the DSpatial rendering engine will compute thousands of pertinent variables and recreate the room for your scene with unbelievable detail. No other reverb engine on the market comes close to this level of artistic control and creative power.

3 - Maximum time range

Just change size

Adjusting reverb times can prove to be a real challenge.
With DSpatial, you can change the reverberation length from 0.1 to 10 seconds without having to change presets or readjusting any other settings.
The size and length of our featured IRs can be modified to match the space being simulated while retaining sonic integrity and character, making programming much easier.

4 - Maximum immersion

Close your eyes and feel inside

When multiple mics are used to capture the impulse response of a room there is a compromise between imaging and envelopment. Adding extra microphones to support yet more channels yields a diminished return because of the loss of spatial resolution due to microphone directivity leaks. Thus the compromise between the number of channels and the necessary de-correlation in the diffuse field makes impossible to record optimally decorrelated responses of more than five or six channels. For an N-channel convolution reverb to be feasible it was essential to develop also an N-channel impulse response modeler: our Physical Modeling rendering engine.

5 - Outstanding sound quality

Convolution reverbs depend on high quality Impulse Responses, which in turn depend on good acoustic recordings and skilled miking technique and practice.
With modeled IRs there´s no need to use microphones record and loudspeakers to excite the room.
To create a new space IR with DSpatial Reality you don´t need microphones, loudspeakers, pseudorandom sequences, shots or sine sweeps. Virtually zero coloration and zero distortion is now possible.

6 - Maximum dynamics

When recording IRs with microphones there is a natural limit of the dynamics mainly due to ambient noise and general noise floor levels. With modeled IRs there is no theoretical limits. For practical purposes we established a dynamics of more than 120 dB. A dynamics even superior to the highest quality hardware based algorithmic reverberations.

7 - Full downmix compatibility

Impulse Responses recorded with microphones have a design flaw. The unavoidable delays between channels provoke undesirable comb filtering effects when downmixing. This flaw makes them unadvisable for multi loudspeaker formats.

With DSpatial Reality you could downmix to any multichannel format, stereo or even mono, without comb filtering, phasing or any other unwanted artifact. Actually if you´re using DSpatial you may not need to downmix at all because of its multiformat capability. But your mix will be downmix-proof in case it´s ever needed.

8 - Full control

Having full control of the IR creation and rendering process allows us to get hold of the level of complexity required to achieve the perfect simulation of real acoustic spaces.
This exclusive feature also provides the foundation to create the complex early reflection patterns needed to realise our ultra-realistic binaural spatial simulation.

9- New acoustic worlds beyond physical limits.

By using its exclusive Physical Modeling Engine, DSpatial is able to recreate any existing acoustic space.

But also by exceeding the limits of physics it is also able to create non existing acoustic spaces, that is completely new sonic worlds impossible to capture with microphone recording techniques, converting DSpatial into a true creator of new acoustic worlds.
