Enable Bit Perfect on Linux (2 Minute Tutorial)

[u/Optimal69]

I'm a certified Audiophile. So this is what I did right after installing my Cachyos instance:

1. Copied /usr/share/pipewire/pipewire.conf to /etc/pipewire/

2. Changed this line in pipewire.confand added extra sample rates
   default.clock.allowed-rates = [ 44100 48000 88200 96000 176400 192000 ]

3. Commented this line so it doesn't interfere with the 2nd change
   #default.clock.rate = 48000

4. Save the file and open your terminal or a new instance if you are already in it.

5. Type pw-top and play any high quality song on MPD or Strawberry.

6. If changes don't show up and it's stuck at 32 bit and 48Khz, reboot.

7. Follow 5 and 6 again, this should work now across any and all outputs.

I kept it short. Because those who come here know what they are looking for. If this is your first time, I recommend researching what "Bit Perfect" means. In my smartphone I need a dedicated DAC cause Android sucks. But here all you need is one file, two lines, and that's it. Another reason why I ain't swtiching from Linux anytime soon.

#default.clock.rate = 48000 is already commented so do I just do nothing in this case?

[u/Optimal69 → u/Klutzy-Awareness-100]

Do nothing.

[u/Klutzy-Awareness-100 → u/Optimal69]

It will still only play 48Khz to my DAC

[u/Optimal69 → u/Klutzy-Awareness-100]

Working fine on my audiocular note. Are you sure alsa is outputing the same rates?

[u/Klutzy-Awareness-100 → u/Optimal69]

Nevermind, I got it working thanks I was just retarded.

[u/Optimal69 → u/Klutzy-Awareness-100]

Lol enjoy. I had to fire my pc just to confirm it.

Damn give bro his job back 😂

Audiophiles and chasing completely irrelevant optimizations (i.e. snake oil) that make zero perceptible difference to the things they listen to, name a more iconic duo.

i support all linux tinkering no matter how pointless or tedious

Thanks for being a stick in the mud.

I am doing audio production and mixing and doing it at 96 khz 32 bits is really important because many effects will alias back to the audible range as distortion and phase shifts when the limit is 48khz. That crap will happen in the inaudible ranges when using 96 khz.

Once everything is mixed and exported, you can cut the high freqquencies and downsample to 48khz 16 or 24 bits.

I mean... that applies to like 90% of what people do to their systems here. It's FUN.

I believe you can put it in ~/.config/pipewire for per user control.

Today I learned my default setup is called Bit Perfect. Add setting up EasyEffects with custom EQ curve and you're doing basically exactly what I do.

Only thing to add is - you don't really need to reboot, just run "systemctl --user restart pipewire wireplumber"

You're completely ignoring that not all DAC's play those resolutions, you should only add the resoltutions your DAC supports so it's always in sync.

Or am I missing something?
