First Lemmy post for me!

I was going to post on /Linuxquestions but I thought I would try here first.

I have an imac2011 which I ran Ubuntu 23.04, Kubuntu and Ubuntu Cinnamon. I discovered Easy Effects audio app which allowed me to download profiles to enhance the audio from the system.

I recently decided to try OpenCoreLegacyParcher and installed a newer version of macos, which is currently running on my system and the audio quaility is just breath taking compared to Linux.

Is there anyway I can get closer to audio from macos on Linux? I’m considering going back to Linux soon but I think i’ll miss how good the audio is :(

    Hello, I don’t think its a driver issue but its more of tweaking issue.

    Is there anyway I take make an EQ based on the audio output on macos? I don’t think my ears are good enough to remember the sound output on macOS for me to then replicate in Linux when I switch over

      That’s an interesting thought and you could potentially even do that using commodity hardware.

      You could create a sound file which first plays a few short beeps for synchronisation and then does a sweep of the full frequency range. You’d then play that file back in macOS and in Linux at the same volume and record it with a mic in a fixed position.
      Then you’d take the two recordings, line them up using the synchronisation beeps and compare the amplitudes of any given frequency. From that difference you could infer the EQ you’d have to add on Linux to get the same frequency response as macOS.

      I don’t know how exactly you’d do the last step but it should at least be possible.

      Mic quality (beyond a very basic point) or colouring should be an issue since you’d have the same mic frequency response in both tests and only care about the difference.
