audioRecorder configuration for modulation
I have developed an application to transfer data via sound. I have a few questions about recording the sound signal and using a library to modulate the FKS. The library that I used can be found here.
Here are my questions:
What is the best configuration of AudioRecorder on Android (PCM
8-bit or 16-bit)?How should the parameters be optimized for the sound signal? Would a 44100Hz sampling rate be optimal? (I
emphasize that I care for higher frequencies such as 16kHz-22kHzrather than speed)- Would a less Baud Rate be better?
Regarding this library, I have a problem with the synchronization in that I need two devices simultaneously playing and listening. The data, which is not rzucało 'junk' or whatever, went on the other phone and I noticed that the problem is with listening or playing because the inside of the data encodes and decodes properly.
