Most everything in the ubuntu store is open source code.
Linux had Audio Hell in the 2000’s I use Lmms, ardour, and Audacity, and I dont have any problems. I have all 3 operating systems. I rarely use Mac. Though it isnt extremely powerful. 2014 mbpro.
Mac has the affinity designer art program, and photoshop, I have them, but I dont use them at all.
I’ve gotten really productive with Krita, and Gimp. I’ve made so many brushes, stamps, and tools. It’s easy.
Game sounds is something I’ve been trying to get better with. It isnt the operating system to blame. It’s my skills.
I have logicpro, and garage band, but I still prefer Linux. I cant complain about the UE4 build. It works great. I only complain about issues with the gpu drivers.
Linux obviously has the capabilities to outshine for gaming, and graphics performance. It doesnt though depending on the gpu, and drivers.
For Audio, and Video take a look at Ubuntu studio. It comes preloaded with a lot of goodies even Linux afficianado’s didnt know existed.
We used to have artist-x, but it died. this kind of filled in the void Features: Audio – Ubuntu Studio
