When I try to launch the “measure impulse response” tool, an error message appears: “In Prepare error – closing convolver!”.
The measuring system in ODEON requires that both an input and output audio device are available. Some sound cards make their devices unavailable to Windows if no cable is connected. Connecting the microphone to the microphone input on the sound card (or any 3.5 millimeter jack) solves the problem. You can then select the correct […]
The Soundscape App doesn’t load on my web browser.
If the files are stored online, depending on your internet connection, it might take a while to load all the needed files to run the Soundscape App. A loading message is supposed to indicate when loading is completed. However, depending on your browser, the information might not be accurate enough and you may need to […]
Why does the BRIR not correspond to what I see in the reflectogram?
The reflectogram is based only on early reflections, while the BRIR (Binaural Room Impulse Response) corresponds to a full response. The reflectogram and the decay curve are shown in a dB scale, whereas the BRIR is displayed in a linear scale. In addition, the BRIR includes all frequencies. The low frequency contributions, that are almost […]
In my auralisation, the difference in strength between left and right ear is very large, even though they are only 14 cm apart; is it a mistake in the ODEON calculation?
The difference in strength is not a calculation error, but arises from the physics of sound propagation around the head when not facing the source directly. At high frequencies (short wavelengths), the head acts as a barrier for the ear on the far side. The direct sound from the source does not reach that ear […]
What type of headphones should I use for auralisation?
Any Hi-Fi pair of headphones will perform well for auralisation purposes. In the auralisation setup, the user can specify the name of the headphone model from a default list so that its frequency response will be compensated. If the model of the headphones used is not available, then choose the generic setting Subject_021Res10deg_diffuse.hph. You can […]
