Auralizing your space

You can click on the Auralizer button to listen to the auralization of your simulations from the receiver positions.

To start the experience you need to add anechoic sounds to sources, select a receiver and click the play button to start the auralization.

For a given source, click "Add sound +" to open the Sound library and choose an anechoic sound.

It is also possible to load your own sound files in .wav format. Keep in mind that the sound will not be saved in the sound library and has to be loaded again for each source, and after exiting and entering the Auralizer again.

Setup

Receiver positions

Select a receiver position to listen to the anechoic sound of your choice convolved with the spatial impulse response of that receiver. The camera will be moved to the receiver of your choice. Click again on that receiver to return to the default 3D view of your model.

You can switch between receivers while playing and pan around with the mouse to simulate different head orientations in the auralized sound field. The binaural rendering is currently powered by the Omnitone library. The Head Related Transfer Functions (HRTFs) employed correspond to the KU100 Neumann dummy head binaural stereo microphones, as recorded for the SADIE dataset, subject two. Check out our paper for more technical details.

Look at sources

You can select a source to look at when switching between receivers. Click the source marker or label and this will set that source as the direction that the camera will be pointed at when you switch between receivers.

Changing input volume of sounds

The source slider changes the input volume of your anechoic sound. Changing this slider will affect the sound level balance between sources when more than one sources are simulated. You can also mute a source by clicking the Mute button. We currently support a maximum of 5 sources playing all at once.

The Master volume (rightmost slider) changes the overall level of your auralization.

Hover on the headphones icon to listen to the original anechoic sound, without the impulse response.

Comparing auralizations

Click the plus button to compare the current simulation with a different one. You will get a list of simulations that are in the same space and have the same amount of sources and receivers, which are placed in exactly the same positions. We currently support a maximum of 6 comparisons.

Select the simulation you want to compare to. With the sound on, you can now switch between simulations by clicking each simulations letter. For example the A in the 'Office test' simulation in the image above.

Exiting Auralizer

To exit the Auralizer press the Exit Auralizer button beside the Results button.
