well you have pure data, max/msp, reaktor, etc for that. These experiments with ML can approximate the soundwaves generated by particular instruments where the soundwaves produced are very complex, but other than that there are tons of software that can help you design any sounds you like. Machine learning is like the micro thing in the 70's-80's companies are trying to put it everywhere they can despite there are no benefits to the existing convenient products/solutions or not incorporating ml at all but still labeling the product. i.e. quoted from wiki: Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter. I see nowhere the 10^-6 meter waves being used in our commonly used kitchen appliance
