Having composed tens of tracks and shorter tunes in a truly wide veriety of genres, from modern/classical Western (orchestral) and even medieval to Turkish, Arabic and Asian, and having made several sounds of my own, some of which can be found at https://freesound.org/people/sonically_sound/, I guess I can call myself a professional composer and sound designer. I have been looking for ways to make some money out of these things because I am into sound design and audio games myself, so I would also love to enjoy the games I played with my own stuff. One of the tracks you hear in DDHeroes was already made by me. So how do I go about doing this? There are a bunch of websites out there but most require images to be uploaded along with your tracks and SFX. Since iOS is a platform where you do get what you deserve in financial terms, unlike Android where people just crack your game and download APK's from other websites, I also expect developers making games for iOS to pay me what I deserve too, as I will be contributing to their games.
