I played a bit with the filters and oscillators of a free vst synth. This sound is useful for cutting and applying different effects over it. I think that it can be used standalone as well.
A simple ringtone from star trek: into darkness created with after effects. It was simply a sine wave produced in adobe after effects, edited with a few volume adjustments.
This is a sound effect i created using chiptone. You don't need to credit me. You can download this sound effect as needed and use it for any project. I would appreciate it if you support me on ko-fi: https://ko-fi. Com/staycalm182.
