Hi @Majuto you will need a 3rd party convolver to host the filters. Depending on the convolver, a virtual audio driver may be required to "loopback" the output from Qobuz into the convolver and then out to your DAC. On Mac, BlackHole is a virtual loopback driver that works well, along with...

Yes, I would start with a 6 kHz HF shelf and adjust a few dB up or down to taste. A 65,536 tap FIR filter has more than enough frequency resolution. The low frequency limit of a FIR filter is typically 3 x the frequency resolution, which in the previous example is 0.732 Hz. So the filter is...

@GoldenOne , I agree with everything you are saying, however, I think you may have overlooked the high frequency response limit of the chart that @Rayon posted. The chart goes up to 3 kHz... Accurate Sound's convolution filters do not eq HRTF. There is no eq beyond 6 kHz, other than like you...
