Multiple and additional eq-prests

Post by hhasert » Sun Oct 11, 2020 3:51 pm

I have been looking at Wavelet which allows you to flatten the frequency response for your headphones using the data from https://github.com/jaakkopasanen/AutoEq . I have attempted to create settings for my Sony WH 1000XM3 based on the rtings profile (https://www.rtings.com/headphones/1-4/graph#678/3992) and I must admit it really improves the music quality (removing the Sony excessive Bass ;-)
Any plans to integrate this capability in Neutron ?

For those interested, I came up with (vamping the 11 band equalizer) :
<preset id="34" name="11-Band Sony WH 1000XM3" bind="0" lock="0" preamp="-0.400000">
<band type="LOWSHELF" gain="-5.0" freq="100" Q="1.25" />
<band type="PEAKEQ" gain="-6.0" freq="150" BW="1" />
<band type="PEAKEQ" gain="0" freq="1000" BW="1" />
<band type="PEAKEQ" gain="1.3" freq="1400" BW="1" />
<band type="PEAKEQ" gain="1.0" freq="1500" BW="1" />
<band type="PEAKEQ" gain="0" freq="2000" BW="1" />
<band type="PEAKEQ" gain="3.0" freq="4000" BW="1" />
<band type="PEAKEQ" gain="6.0" freq="5000" BW="1" />
<band type="PEAKEQ" gain="0" freq="7000" BW="1" />
<band type="PEAKEQ" gain="-5.0" freq="10000" BW="1" />
<band type="HIGHSHELF" gain="8.0" freq="16000" Q="0.707107" />
</preset>

You can create equalizer presets in neutron, see for example my preset for my Sony WH-1000XM2, first in edit mode :

What I mean is that in Wavelet I can just select the headphone and it creates the right equalizer profile for it. That would be a perfect option.

So you'd like to have predefined EQ-presets for some ( or most :D ) headphones ?

Yes, the popular ones, not sure if there is an easy way to generate them from the measurements, probably running the python scripts they provide do the trick ( on a holiday now so no time to dig in). What wavelet does is on os dsp level and i think 16 bit, so i cannot trick it by selecting system dsp in neutron ( which is what they suggest) . Have a look at https://github.com/jaakkopasanen/AutoEq which is the base for wavelet to get the eq settings. I read there is a include that might do some tricks, hopefully easy to integrate :lol:

How do i enable the cumulative plot ?

OK, so you propose the developer somehow gets the data, creates EQ-presets for Neutron and adds them to the installation. Another thing that might be helpful : it seems that in wavelet you cannot only activate an eq-preset to mitigate your headphone's gravest shortcomings, you also can add sound improvements. Which are already present in neutron's existing presets, but in Neutron you only can activate one preset at a time. To do the things in neutron that wavelet can do we'd have to be able to activate two presets - one for the mitigation and one for the improvement.
