  • Method Details

    • startCapture

      public void startCapture()
      Starts the capture. If there were previously recorded samples, they will be overwritten by this method.

    • capturedSamples

      public int capturedSamples()
      Returns the number of captured samples.
      Returns:
      number of samples

    • fetch8BitSamples

      public void fetch8BitSamples(ByteBuffer buffer, int samples)
      Retrieves pcm data from the input device and saves it to a ByteBuffer. Use this for 8-Bit data only unless you know what you're doing.
      Parameters:
      buffer - the buffer
      samples - number of samples to fetch

    • fetch16BitSamples

      public void fetch16BitSamples(short[] buffer, int samples)
      Retrieves pcm data from the input device and saves it to a short array. Use this for 16-Bit data only unless you know what you're doing.
      Parameters:
      buffer - the buffer
      samples - number of samples to fetch

    • fetch16BitSamples

      public void fetch16BitSamples(ShortBuffer buffer, int samples)
      Retrieves pcm data from the input device and saves it to a ShortBuffer. Use this for 16-Bit data only unless you know what you're doing.
      Parameters:
      buffer - the buffer
      samples - number of samples to fetch

    • stopCapture

      public void stopCapture()
      Stops the capture.

    • getDeviceName

      public String getDeviceName()
      Returns the device name.
      Returns:
      the device name

    • getPcmFormat

      public PcmFormat getPcmFormat()
      Returns the pcm format of the device.
      Returns:
      the format

    • getFrequency

      public int getFrequency()
      Returns the frequency of the device.
      Returns:
      the frequency

      Returns:
      list of devices

    • getDefaultDeviceName

      public static String getDefaultDeviceName()
      Returns the name of the default input device.
      Returns:
      name of the default input device

    • open
