Thank you for sharing some very good examples that work in real life. To be honest, I tried everything many years ago, but I like the inversion trick more than the others. By the way, I noticed that
royalty free sound effects for commercial use are so often used in this area, especially for MOD. Sound effects are useful to apply to make the sound cleaner, without noise. However, I also tried some effects that ruined my music, which I couldn't restore. One thing I understood for sure: it is impossible to write a good track without using sound effects, but you need to be able to apply them correctly.
