In all my time spent in studios and live music in the past 20 years, I've never encountered an A/V professional using Linux. I don't work in video production but I know several people who do, and I've watched some documentaries on this -- in that case, the proportion of Apple machines seems to be even higher than the already quite high proportion found in audio. Never seen a professional or semi-pro using a Linux box. I'm sure they exist, but this doesn't track at all with what I know about this industry.
Sometimes a DJ or bedroom producer is using Windows. So it's quite surprising to hear you say that Linux is the standard.
Can you point me to any producers, artists, sound engineers, studios, or production houses that use Linux? I would love to know...
I have never seen anyone using CALF tools in this profession. Looking at what that does - the functionality is available in a number of rock-solid applications native to Apple (MainStage, Ableton, Logic, etc). So there's no reason why it would need to be ported to MacOS.
How are you measuring audio stack superiority? And in terms of "stack", are you talking about something separate from the suite of professional audio / MIDI tools that come standard on every Apple computer that don't seem to have any comparison on Linux or Windows?
Are you taking into account the availability of hardware drivers on these different platforms? What is your experience in setting up a Linux-based audio production system with a lot of outboard gear? This is one area that seems to be a major source of headaches and motivation to not use Linux for producers and engineers.
Even looking through the comments on this page - there's people talking about the difficulty of setting up a functional audio production environment in Linux compared to Apple. I've noticed this sentiment is repeated over and over again on HN (going back to previous articles on audio production, Ableton, etc).
This topic stands out to me as I've sincerely wanted Linux to be much less of a headache with audio so I can get off the Apple ecosystem entirely.
