ash-listening-set's Issues

Why removed reverberation?

I'm curious if there's a possibility that larger rooms could also come alongside a version with their original reverberation, like the Small broadcast studio

Request for more info on the virtual rooms

I can't exactly discern the source of R18 (Small Room I) and R20 (Small Room A) to R33 (Studio B). What database(s) do these rooms come from? R32 (ASH Listening Room) is definitely directly from this project, so I also wonder how it is made and what its goals are supposed to be. I seem to be preferring it over R03 (Control Room 7).

Question about stereo upmixing

All of the audio content I listen to only uses 2 channels, but I would still like to use all of the BRIR .wav's instead of just the A-30 and A30 .wav's for stereo content. However, this project doesn't have a suggestion for how to upmix stereo for this purpose. I have been able to find an idea from HeSuVi (Copy: L=0.5*L R=0.5*R C=0.2*L+0.2*R SUB=0.0 RL=0.3*L+-0.2*R RR=-0.2*L+0.3*R SL=0.45*L+-0.25*R SR=-0.25*L+0.45*R, though I just multiplied all of the values by 2 to result in Copy: C=0.4*L+0.4*R SUB=0 RL=0.6*L+-0.4*R RR=-0.4*L+0.6*R SL=0.9*L+-0.5*R SR=-0.5*L+0.9*R), but I don't know if this makes sense/is valid for this purpose, nor do I know if this specific upmix is for narrow 7.1 or wide 7.1.

Here is what my current configuration looks like:

Question on some HPCF file

Hello. Could you point me please what source of measurements you have used to generate EQ for Sennheiser 650_Sample_B?

Linux support

EasyEffects with PipeWire made Linux more audio capable & easy to use than ever before. But not for virtual headphone surround yet. Although, virtual surround support is possible with Pipewire, it is finnicky to set & implement.

In the future, wiki implementation would be nice to address easy & user-friendly Linux support.

Differences in peak gain

Hi again, I'm really loving this project and how far it has come. However, there's on thing I would like to bring up. Each HRIR has it's own peak volume and so in order to eliminate clipping, you have to change the preamp according to the room every time you switch them. I know, there's tools like peace UI that solve that problem but I was wondering if you could make the room files have a more equal peak gain. Thanks in advance

Pipewire configuration problem

Here I don't have filter-chain.conf.d/virtual-surround.conf

The content of that folder is:

demonic.conf sink-make-LFE.conf sink-virtual-surround-5.1-kemar.conf source-rnnoise.conf
sink-dolby-surround.conf sink-matrix-spatialiser.conf sink-virtual-surround-7.1-hesuvi.conf
sink-eq6.conf sink-mix-FL-FR.conf source-duplicate-FL.conf

Generate HeSuVi-compatible WAVs

Is there a possibility the BRIRs can be processed as HeSuVi wav files?
HeSuVi is the generally the most used method for surround sound with Equalizer APO. There may however be issues as HeSuVi takes 48KHz files, with 44.1KHz being secondary.
