Hi all!
How does HQ Player's work regarding the bit depth and sample rate when using its convolution engine?
To clarify my question, let me explain why I am asking:
I am using HQ Player to set the bit depth and sample rate from Roon at 24 bit 44.1/48 kHz, as my preamp and DAC are limited to these. In the mean time, I am using the convolver to try to linearize the phase of my loudspeakers. So far, when I generate an impulse using Rephase, I set the bit depth to 32 bit and the sampling rate to 176 kHz. My hope by doing this is to minimize the possible artifacts from the convolution when the music is 16 bit 44.1 kHz.
So, does HQ Player up-samples the music to match the impulse, then convolves and then down-samples to match my resolution requirements? Or does it simply down-samples the impulse to the music, then convolves and then matches the obtained result to my required resolution? If the latter is done, does it have some drawbacks regarding convolution artifacts (quantification noise, or other)?
Cheers!
