title: JavaSound writing to audio file with a stream
body: <p>I'm attempting to create an audio filter using the JavaSound API to read and write the audio files.  Currently my code is structured as follows:</p>
  
  <pre><code>        ByteArrayOutputStream b_out = new ByteArrayOutputStream();
  
          // Read a frame from the file.
          while (audioInputStream.read(audioBytes) != -1) {   
              //Do stuff here....
              b_out.write(outputvalue);
          }   
  
          // Hook output stream to output file
          ByteArrayInputStream b_in   = new ByteArrayInputStream(b_out.toByteArray());
          AudioInputStream     ais    = new AudioInputStream(b_in, format, length);
          AudioSystem.write(ais, inFileFormat.getType(), outputFile);
  </code></pre>
  
  <p>This reads the input file as a stream, processes it and writes it to a bytearrayoutputstream, but it waits until the entire file has been processed before writing to disk.  Ideally, I would like it to write each sample to disk as it's processed.  I've tried several combinations of stream constructs but can't find a way of doing it as AudioSystem.write() takes an input stream.  Any ideas?</p>
