This is a massive thread (hopefully next year have thousands of responses) to share the possibilities of modifications, modulations, tremolations, reverberations, layerations, tricks, techniques, psychoacoustics, processing, victories, defeats, and examples, ideas, interesting results, themes, your process, signal flow, changes over time, unique things other people never thought of...
Once we pass on knowledge to others, it clears a space in the mind where we had this knowledge and that space is then available to be developed with fresh, new ideas. Teaching someone is often the best way to learn. This thread will benefit the person who divulges their experience and it also benefit the person who reads this new idea and is able to learn something new. It's like subtractive EQ by taking away, you are actually adding. People all over the world will look at this thread and if you have time, share something that you have discovered, it might inspire you to create something new, and if you can share that maybe the cycle will continue.
Something that inspired me to make this thread is when I was messing with convolution and I found a clip of laughter. I shortened it to around a millisecond and put it into a reverb and sent it to a mono voice recording. The sound was really happy, way happier than the laughter itself. It sounded almost "pad-like."
