Implement getMaxAmplitude for audioRecord

Question

I am using audioRecord instead of mediarecorder in my app it\'s working fine but I have a logic that depends highly on the maxamplitude which is really hard to obtain using the

Answer 1

int amplitude = (buffer[0] & 0xff) << 8 | buffer[1];
amplitude = Math.abs(ab);

Do you make a mistake here? I think it should be

int ab = (buffer[0] & 0xff) << 8 | buffer[1];
int amplitude = Math.abs(ab);
