Linux support about ash-listening-set HOT 9 CLOSED

I have added steps into the wiki for pipewire / easy effects configuration. Hopefully the steps can be replicated without issues on other user's machines.

I have added steps into the wiki for pipewire / easy effects configuration. Hopefully the steps can be replicated without issues on other user's machines.

Thanks!
I read everything & I find it very good.

The only addition needed, is the last step of saving the preset again, when excluding "effect_output.virtual-surround-7.1-hesuvi". That's because disabling & excluding apps from the audio stream is tied to the preset.

I asked myself before "Why is app excluding not saving" & I found the github issue where developer indicated that you should save the preset after doing that. UI department there needs improvement for sure.

Thanks for bringing PipeWire and EasyEffects to my attention, I was unsure about Linux implementation. I will update the wiki after doing some testing in Linux.

from ash-listening-set.

The current issue is that EasyEffects natively only supports stereo configurations:
wwmm/easyeffects#1126
wwmm/easyeffects#1312

So I think that only stereo speaker room simulation is possible currently.

There is some workaround for upmixing to multichannel If I see correctly:
wwmm/easyeffects#1126 (comment)

But I don't have the configuration to test it.

JamesDSP for Linux has the same issue too:
Audio4Linux/JDSP4Linux#73

I got this working!

Here are the steps to use ASH-Listening-Set on Linux:

1. Download & extract HeSuVi pack of ASH-Listening-Set
2. Install EasyEffects (Avaliable for most distros. Recommendation is to install flatpak version of it from FlatHub for better compatibility)
3. Open EasyEffects, open hamburger menu & in "Preferences"
   toggle on "Launch Service at System Startup"
   toggle off "Shutdown on Window Closing"
4. In "Output - Effects" tab, on left pane, click "Add Effect" than "Equalizer".
5. In "Import Preset", click "GraphicEQ". Apply HpCF for your headphone from "eq/_ASH_HpCFs" folder
   5a. If you are going to use other EQ & don't like the default Diffuse Field target HpCF, than apply "Room_Target_Inverse.txt" from "eq/_ASH_Additional_Filters" folder & than apply your own EQ (either through Convolver, APO or GraphicEQ, depending on what you have)
6. Save the preset & name it however you like.
7. Click "Pipewire" tab, on left pane, click "Presets Autoloading" & here add the autoload preset matching your headphone.
8. For Room Simulation wav file, follow this video, with correction that you should use ASH-Listening-Set wav from "hrir" folder:

9. Once you reboot after all those changes, go to EasyEffects, "Output-Players", than exclude "effect_output.virtual-surround-7.1-hesuvi"
10. Save preset once again.

Enjoy working virtual surround.

So it goes like this:
Stereo - EasyEffects - Surround 7.1 upmix

The only caveat can be increased CPU usage, but I don't have a low-end hardware to test for serious issues.
Another caveat is that HRIR preset changing is not possible to do quickly & you have to reboot for changes iirc.

Thanks for providing the above steps. I tried out EasyEffects on my linux installation and reached step 5, however I'm a bit unsure of the compatibility with the HpCFs. I imported one of the HpCF graphic EQ filters but it doesn't look like all of the frequency bands are loaded in. It seems like it is limited to 32 bands. I also tried using convolution with a HPCF wav file but it only accepts stereo IRs. If this is the case I might need to provide the HpCFs in an alternative format but Ill also do some more testing to confirm.

Oh, I didn't know that Graphic EQ had more than 32 bands.
In that case, you can just load another "Equalizer" effect with "Graphic EQ" option & you gain +32 more bands.

Everything else you said is correct.

I did manage to get the headphone correction step working by converting the mono IRs to stereo and loading them into convolvers within easyeffects. I will have to add stereo versions of the HpCFs to make that step easier for anyone using easyeffects.

I also got the virtual surround working as per the steps provided. There was some popping but that was likely due to me running linux on a virtual machine with limited resources, so CPU usage is probably not a big issue in reality. I think one thing that would be nice is a more convenient way to change between HRIRs/BRIRs so Ill do a bit of digging there.

Closing this issue, as ASH Listening Set gained Linux support.
