Question

I’m recording some audio in an Android app, and now I want to know that’s the samples’ value I’m getting. Since the record is in bytes, I would like to convert it to int or floats, to compare signal levels easier.

I’m trying to do so with this script, but it doesn’t work:

                    byte data[] = new byte[bufferSize];

                    read = recorder.read(data, 0, bufferSize);

                    int dataInt[]= new int[bufferSize];//To convert into int

                    for (int j=0; j<bufferSize ; j++)
                    {
                        dataInt[j]=data[j].intValue();

                    }

Could anyone tell me what am I doint wrong?

Thank you very much.

You are calling intValue() on a primitive byte value! Why can’t you just do

dataInt[j]=data[j];
