Dear client,
This is a pretty straight forward app. With Fourier Transformations, it's easy to identify the vibration points in an mp3.
I am skilled enough to develop you one app that will comfortably work for Android, iOS, and even Windows devices.
It won't take long, and the end product will be amazing. I will also maintain it for you when we host it. This is necessary since App Store, Play Store, and Microsoft Store policies do change from time to time.
I'm looking forward to your confirmative reply.
Should you have any questions, please ask me.
Thanks,
George M
