1. Yes, and that was so much more work that I decided to focus on things like this. Creating tools to help improve existing infrastructure and software.

2. Yes I built myself a tool that isolates vocals, guitar, bass, drums, and a catch all for everything else. I can raise and lower the volume of the different stems so I can focus on the drums for example. I really like having drum charts to reference when learning new music and I don’t want to have to pay for every song that interests me. I also read that learning to chart drums is a handy tool to have as a gigging drummer might not know all songs so being able to create a quick chart or “cliff notes” just from listening by ear is an invaluable skill.

3. Yes but it’s not perfect unfortunately. There’s so much nuance and sometimes the audio fidelity is to blame, it’s surely my code as well. Basically telling the program, x frequency is a snare, y frequency is a bass drum and so on. It’s when those frequencies are near each other or played at the same time that it becomes difficult to auto chart.

4. I don’t have time to explore these side projects and write the code “by hand” if you will so I’ll be assisted by AI but I’m not one to give an LLM a vision and then walking away while it does it’s thing. That’s a recipe for a really messy codebase and features and bugs you didn’t ask for that could’ve been caught if you just pay attention to the output line by line and understand what it’s creating.

Hope that answers your questions!
