Dear list,
Hoping this message finds you all well.
I have two audio signals of music pieces. One is mixed for standard stereo presentation, while the other is a spatial audio mix for binaural presentation.
I am looking to find objective measures that could indicate differences in spatial impression, like perceived "spaciousness" / "immersion" / "envelopment".
I think a consensual metric would be the Left / Right channels IACC (1/3 oct bands).
Besides IACC, I am thinking of using the InterAural Difference (IAD), as suggested by Griesinger ("Griesinger, D. (1999, April). Objective measures of spaciousness and envelopment. In Proceedings of the AES 16th International Conference, Rovaniemi, Finland.).
I am here seeking advice on any other suggestions you might have that could be used on the signal analysis of a continuous 2 channel audio signal.
Also, are you aware of any available software toolbox that would have any kind of this "spatial impression" analysis conveniently implemented?
Thank you for your help,
Kind regards,
- Frederico
