Since it has been some time since my last post, I want to post the current status, even if the current song has not been finished. After I finished the first part of my 7th song, my creative process came to a standstill. In order to bring some variety to my song creation process, I decided to deal more with basic sound engineering issues. When I was very disappointed with the current sound on someone else's sound system, something like an artistic crisis began.
I doubted pretty much everything I had done before, threw certain fixed ideas overboard, added new ideas, discarded them over and over again. This process is actually nothing unusual, and has happened with every album so far, only I was myself sure that this time everything should be clear - a mistake as it turned out.
Especially the sub-bass (for non-nerds: these are those frequencies that you feel more than hear and that you can't even hear with small headphones) had totally different effects on different sound systems. I then began to watch an estimated 20 audio engineering videos that focused purely on this sub-bass and to gather new knowledge to apply them to the new song. After a lot of back and forth, this crisis now seems to be over, and I can go back to composing the 7th song.
