Method Detail

write

public void write(byte[] buffer)
           throws PortAudioException

We will split everything into parts of PortAudioManager.NUM_SAMPLES. If something is left we will save it for next write and use it than.

Parameters:

buffer - the current buffer.

Throws:

PortAudioException - error while writing to device.

start

public void start()
           throws PortAudioException

Starts the stream operation

Throws:

PortAudioException

stop

public void stop()
          throws PortAudioException

Stops the stream operation.

Throws:

PortAudioException

getDeviceIndex

public int getDeviceIndex()

The index of the device that we use.

Returns:

the deviceIndex

getStream

public long getStream()

The pointer of the PortAudio stream.

Returns:

the stream pointer.
