@Chais @n3cr0 how do you replicate that with pipewire anyway? Sure, you can rig up the nodes and all, but are games actually outputting surround nowadays, or how do you benefit from all that work?
Since pipewire is the default in Nobara (I recently started with it), I hope I don't need to care too much about it (fingers crossed!). What I want to achieve is a realistic feeling of the room accoustics in games. I recently noticed that in Cyberpunk 2077 (windows, with the xbox headset): I could close my eyes and still tell where I am in the game.
@n3cr0 ahh, I guess that's more or less normal hrtf, which any respectable audiogame can replicate
Exactly. You set up the virtual sink for 5.1 output and make pipewire convolute the signal with a suitable impulse response to turn it into a stereo signal that sounds like it's coming from the correct direction. And yes, most games will output surround sound, given the option.
@Chais do games actually output 5.1 nowadays? Most of those I know use libraries like steamaudio, which simulates it using in-app hrtf, mixing the signal on its own
At least I can play games and get directional audio. Beyond that I care little how they achieve it.
It depends on the game. I have 5.1 speakers on my computer and can hear things behind me in some games, but not others.
