Software wise, ProTools is what nearly everyone in the industry uses. Its been around forever. It enjoys a massive monopoly share of the market. But I don’t think it works on Linux. Mac n PC only.
For a cheaper Linux friendly option, consider Fairlight (the audio component of Black magic Resolve).
The name “Fairlight” has also been around forever, but was defunct for a while, and a handful of years ago the fine folks at Blackmagic Design bought the brand and IP integrated into their Resolve software. While Resolve has a free tier that includes Fairlight, some might require the Studio version which is a one time fee of ~US$300 and includes all future updates. I’ve heard some Pros speak highly of the new Fairlight. Can’t vouch for it myself but the mantra of the Blackmagic CEO is “we build the tools we wanted when we were working creatives.”
I would help if asked, but I’m not out there trying to convince people. This isn’t the first Windows version to be EOLd, and Apple and Android have all but convinced people that a 2-3 year hardware replacement cycle is normal. I just don’t think this is a significant consumer event at all.
Yeah, but I wouldn’t say “switched” is the right word for me. I’ve been using a variety of OSes for personal and work for a long time. I worked in embedded software, and we had to support a variety of build toolchains for different host OSes and different target OSes. So the idea of using a different OS on my own computer is not a big deal. Over the years it’s been Solaris, BSDos, Mac, Windows, and more flavors of Linux than I can recall.
Not the question you asked, but it was gratifying when Raspberry Pi really started to take off because it was the first time that developing for a different hardware arch and OS target was going mainstream. I would enthusiastically help people with that sort of thing. But even fewer ask. lol
