Ah yeah, you're talking about the New Audio Spatial soundcard that was talked about earlier (https://newaudiotechnology.com/products/spatial-sound-card-2/ ). How did you find it, was it effective? Did you compare it against some other virtual surround solutions?
I compared it to OOYH, the standard HESUVI BRIRs/HRTFs and some free BRIRs/HRTFs that are not included in HESUVI. For movie and gaming some rooms were ok. The problem was that the Spatial soundcard and OOYH did not have any benefit for me compared to some of the free BRIRs/HRTFs.
I copied some of the rooms from the Spatial soundcard and OOYH in HESUVI but never used them. In time I switched to a Impulcifer measurement.
