While experimenting with various filtering methodologies, for example this:
www.audiosciencereview.com
I started using convolution, concretely Jriver's Convolution engine
I have noticed that it introduces quite a lot of delay that can cause audio/video to get out of sync; especially when using external sources like Youtube, etc.
So I started looking for alternatives - please see below some comparison between them
Frequency response using the same wav filter file:
As you can see there is a difference in the level but there is zero difference between the frequency response curves
I could not see any difference in any of the other curves either - please see the measurement file attached for reference; should you notice anything please let me know
Now about the latency, let's play a Youtube video and check delay:
Jriver:
Above 100ms, around 110-120ms
Convology XT:
Around 40-50ms
SIR3:
Very similar, around 40-50ms
HOFA:
This was the lowest, rarely exceeding 40ms
So all in all my conclusion is that I could not find any difference in terms of measurements but there are quite significant differences in terms of delay (especially between Jriver and others)
I add that I also tried ASIO vs WASAPI, the latter resulted in significantly lower latency (using Windows 11 and Topping DM7 DAC)
I hope this helps, please let me know in case of any comments/questions

Using REW's new inversion feature for room correction
I am posting this with the kind permission of @Serkan who drew my attention to this brand new method for room correction In this video you will see how to try this with an early access version of REW, available here: https://www.avnirvana.com/threads/v5-20-10-early-access.10787/ I have tried...
