Parametric EQ settings from AutoEQ gives different results
When importing a ParametricEQ.txt, the plotted graph is quite different from that of AutoEQ itself.
Seems right to me, the thin green line and the plot in DDCToolbox look almost identical.
Could you point out which frequency range looks out of place?
I have the impression that the line is sort of tilted downwards from around 500 Hz onwards. For example, the peaks at 1826 and 7073 have positive amplitudes in the AutoEQ graph, but not when imported into the DDCToolbox. Maybe it makes sense, but I just don't understand why that is.
Yes, you're right. There is some discrepancy between both graphs. I'll have a closer look at how AutoEQ calculates their graphs
Great, thank you! One more thing: shouldn't changing the filter type also change the graph accordingly?
It does, but you need to click in another table cell to commit your change (the GUI library I'm using handles widgets inside table cells a bit strangely)
Example:
You're using the latest stable build right? I just checked and your issue seems to be fixed on the latest version directly compiled from sources. I was rewriting large chunks of the code which handles/stores filters a while ago so that might have fixed it.
Use the latest nightly release instead: https://nightly.timschneeberger.me/ddctoolbox-win/ddctoolbox-win64_1.3.85.zip
By the way, this version can download profiles directly from AutoEQ (File > Download from AutoEQ)
Thank you for your help. I was indeed using the latest stable build. The latest nightly build gives more similar results, but still they're a bit different (negative instead of positive 7073 Hz peak for example). Do you know what's the reason behind this?
Another problem I now have with the latest nightly build is that it crashes when I import a VDC file.
Could you upload the VDC file that crashes the app? Also, you can only import 'classic'-VDCs (VDCs that only contain Peaking filters) I'll also look into the other issue
I couldn't reproduce the crash you described (on version 1.3.85). However, I noticed some VDCs are falsely recognized as not compatible. That issue should be fixed with the latest nightly build: https://nightly.timschneeberger.me/ddctoolbox-win/ddctoolbox-win64_1.3.90.zip
There still seems to be a problem with autoeq downloads and imports. As you can see the gain levels are significantly different. The VDC files also sound very different than the convolver files (especially the SE846), so something is wrong:
Note all gains are negative.
and
Note the treble gains are much higher.
Manually adding Low/High Shelf helped for me:

After vs AutoEQ graph
