The advantages of modeled IRs
over
microphone recorded IRs

1 - Unparalleled speed

Find your best room for any situation in seconds Playing back IRs from a standard convolution reverb may require a substantial amount of time. With DSpatial Reality the best room for any situation can be found quickly and because of its intuitive modeling structure, specific parameters can be modified to suit any individual project. If desired, adjustments can be saved as presets and used as a starting point for other projects.

2 - Flexibility

Change size, shape and surfaces* Model the acoustic and physical properties of any room on the fly. Adjust the size, shape and surfaces included with the desired environment and manipulate any acoustic parameter, like the amount of glass, absorbers or diffusers present. To make it even easier, a relevant combination of options has been included, and once modified the DSpatial rendering engine will compute thousands of pertinent variables and recreate the chosen room with unbelievable detail. No other reverb engine on the market comes close to this level of artistic control and creative power. *Available in Reality Builder versions

3 - Maximum time range

Just change size Adjusting reverb times can prove to be a real challenge. With DSpatial, the reverberation length can be changed from 0.1 to 10 seconds without having to change presets or readjusting any other settings. The size and length of the 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 it 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 an N-channel impulse response modeler as well: Enter DSpatial 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 a dynamics of more than 120dB has been established, which is far 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-speaker formats. With DSpatial Reality downmixing to any multichannel format, stereo or even mono, without comb filtering, phasing or any other unwanted artifact can be achieved. However, because of DSpatial’s multiformat capability, downmixing is not needed. Should it ever be needed the mix will be downmix proof.

8 - Full control

Having full control of the IR creation and rendering process allows DSpatial 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 DSpatial’s ultra-realistic binaural spatial simulation.
