96khz Sample Rate Binauralizer?

[hockinsk]

Hi, I can see 44.1 or 48 support in the Binauralizer VST plugin code. Would it be possible to release a 96khz version? I would attempt to build it myself, but don't have the experience building VST or setup for development.

The 48kHz suggestion is largely due to the included/default HRTFs having been measured/modelled at 48kHz.
However, I don't think the plugin will stop you from using other sampling rates, despite the warning.
I see now that it also resamples the HRIRs if they do not match the host samplerate.

However, I remember testing the resampler a while ago, but I wasn't completely happy with it, and so the 48kHz recommendation stood.

So, if you are reading this, and are able to help with improving the resampler, please go ahead/get in touch:

I was working on an Intel IPP wrapper, but I was running into platform-dependent issues (which I think may be down to memory alignment issues, but I couldn't figure out why). Otherwise, the SPEEX resampler is of course fine, but it's more optimised for speed. I would say for this HRIR resampling task, favouring accuracy would probably make more sense (since this resampling would be done in an offline stage anyway).

Because of sample rate, I can't run binuralizer under foobar2000 vst plugin or izotope RX 11. It seems it doesn't detect the resampler I insert before it can suggesting a sample rate mismatch. izotope resampling quality is amazing, but I guess it's propietary algrithm.
