I have created a tuner (frequency finding) application on Android and it is using FFT algorithm but FFT is not written by me. I want to record auido in the application also but not successfull until now. When I create different Android app project, I can success to create an audio record app and it works. But when I implement codes to tuner app, it doesnt work. It creates "record.3gpp" in device storage but no play , because It is 0 KB. That means , it doesnt record. Why this happens ? I have some values during voice processing, sample rate and buffersize. private static final int SAMPLE_RATE = 24000; private static final int BUFFER_SIZE = 4096;
Maybe this values blocks auido recording. Do you have a suggestion ?
