Hello Julian
thank you so much for this one, I am very interested. I will download and test it and be in touch with you.
congrats on your work.
best

Hi Jose,
I’m sorry for arriving late to the party, but I think you maybe interested in [hrir~], a spatializer that allows you modify distance besides azimuth and elevation. This object is based on Qu et al. database, I have equalized it to remove the effect of the measurement apparatus, and resampled it to use it with different sampling rates. Note that [earplug~] is based on the MIT database recorded at a fixed distance (1.4 m, IIRC) and a sampling rate of 44.1 kHz. That means that if you want to use it at a different sampling rate, the binaural image gets distorted.
Binaries, source code and databases at different sampling rates are here:

My student and I are working on a new version that includes the two different pinna simulators used by Qu and colleagues (currently, only the right —small—pinna is used). We’re also working on improving the scalability of the object. If you’re interested, on learning more, please let me know.
Details of our method are found here:
