Tuner

public Tuner(Device device,
 PcmFormat format,
 double bufferSecs,
 int recoveryAttempts)
      throws IOException

Creates a tuner to input PCM from the given device in the given format, specifying the size of the external buffer, and the number of recovery attempts in case of buffer overrun. Available devices are obtained through devices. A reasonable number of recovery attempts is 2 if you want to continue receiving after a stutter in the input, or 0 if you want to get an exception as soon as an overrun happens.

Throws:

IOException

Method Details

read

public boolean read(ByteBuffer dest)
             throws IOException

Description copied from interface: PcmReader

Reads frames until buffer is full, input is exhausted, or the source is closed. Returns false if input is exhausted, true if the source may provide more data.

Specified by:
