Question

I'm manipulating .wav audio files in Android.
So far things are going well (I can record a .wav file from the mic, add echoes etc.), but I'd like to mimic the behaviour of sf_readf_double() and sf_writef_double as per libsndfile in C++ to implement more complex filters.
I have a com.sun.media.sound.WaveFileReader and WaveFileWriter objects and I'm getting at the audio data using

stream = wfr.getAudioInputStream(new File(inputAudioFileName));

which returns an AudioInputStream.
Is it just a case of reading 8 bytes from the stream at a time into a double or is there more to it than that? I'm a little confused as other filters I'm using seem to manipulate shorts rather than doubles.
