Hi, I've used RAD studio Tokyo/Delphi to create a program for Android. I have this program working and looking good on my Amazon Fire. It occurred to me that a nice embellishment for this program would be a click sound for when the user presses a button...feedback. I remember about 35 years ago when Casio came out with calculators that could beep for each keypress. I found this useful and missed it when they stopped including sound a couple of years later.
I started to research this and found that Android prefers .3GP audio files. There don't seem to be any audio files on the fire.
What I am thinking is I would produce four very short audio files and save or convert them to .3GP. They would be tied into buttons as part of an on-click event. I would use a TMediaPlayer. There would be a tick, a tock, and two other similar sounds.
My questions are: Should I use one Media player, or four ? Are there no built-in sounds I can use, or a different way to generate sounds ? Or is this all a bad idea perhaps because it would be too much for the Fire ? Should these files be stereo ? What sampling rate and bit depth ?
