    • getAudioInputStream

      public AudioInputStream getAudioInputStream(File file) throws UnsupportedAudioFileException, IOException
      Open an audio input stream. If the file is a Wav file, then it will attempt to read the file with PAMGuards bespoke audio stream reader. This includes support for wav files which are > 2GByte in size and also works for floating point 32 bit files (which the Java one doesn't). If that fails, or if its not a wav file, then the standard java AudioInputStream is used.
      Parameters:
      file - file to open
      Returns:
      a new audio input stream
      Throws:
      UnsupportedAudioFileException - thrown if it can't understand the audio format.
