@juicehifi Thanks, I'm going to explore your suggestions with the CPD... However, the agressive top is noticed with all target curves I have implemented. I attach below a few screenshots with different target curves. The GD and IR are identical to the posts at the top...

The treble issue visible on one channel has been resolved, but the sound imaging has not improved. The TTD correction was halted at 4000 Hz for the affected channel. However, the Group Delay still seems unusual, as the curve behavior below 100 Hz appears to be inverted.

Dear All, I would appreciate your thoughts on the way the FIR filters in my system are currently being generated. From my assessment, the Group Delay and Impulse Response appear to be optimized correctly. However, I’m experiencing an issue with the sound imaging—it doesn’t seem as well focused...

Do you think the Hapi is superior due to its advanced hardware or its ability to produce more accurate measurements?

I agree that a converter chip does not do the whole job... how the DAC is built around is also very important!! Thank you :-)

Do you hear a sound improvement compared to the Motu?

I heard about these delays... Did you find high quality DAC with more channels? I would enjoy finding a 2x5 channels high quality DAC...

Thank you for these advices. They are very useful. I note that you are using the Motu for both your measurements and the audio DAC. I would need to exchange my Topping DM7 against a Motu for convenience unless I accept to unplug/plug the 8 TRS cable during each measurement session... In this...

I see your point... Since I need 8 channels of output, the Focusrite Scalett is not the best match because it has two output channels. I need to upgrade to an 8 channels interface...

Unfortunately the results using WASAPI were even worse... I'm curious to know what kind of unique interface allowed you to fix all the problems...

Unfortunately, the native ASIO drivers Topping DM7 ASIO and Focusrite ASIO do not seem to work together... this is why I use ASIO4ALL.

I thought ASIO4ALL is the right tool for both input and output... I will try the native ASIO driver!

Thank you. I tried what you did: increase the memory size and reduce the sweep time... This is not perfect because I still have about 50% of waste but it is still a significant improvement. The question is how clean must be the sweep recording?

Hi All, I stop this thread as another one has been started earlier by whoareyou on the same topic. Thanks. Olivier.

Hello all, I'm interested to know how the memory allocation for AL can be increased, as I face to similar problems :-) Many thanks in advance, Olivier.
