Constructor Detail

InputPortAudioStream

public InputPortAudioStream(MasterPortAudioStream parentStream)

Creates new input stream (slave) with master input stream.

Parameters:

parentStream - the parent/master input stream.

Method Detail

read

public void read(javax.media.Buffer buffer)
          throws PortAudioException

Reads audio data from this InputPortAudioStream into a specific Buffer blocking until audio data is indeed available.

Parameters:

buffer - the Buffer into which the audio data read from this InputPortAudioStream is to be returned

Throws:

PortAudioException - if an error occurs while reading

setBuffer

void setBuffer(byte[] bufferData,
               int bufferLength,
               long bufferTimeStamp)

Sets the audio data to be read from this InputPortAudioStream upon the next request. Used by parentStream in order to provide all audio samples to all its slaves and not only to the one which caused the actual read from PortAudio.

Parameters:

bufferData - the audio data to be read from this InputPortAudioStream upon the next request

bufferLength - the number of bytes in bufferData which represent valid audio data to be read from this InputPortAudioStream upon the next request

bufferTimeStamp - the time stamp of the audio data in bufferData represented in accord with Buffer.FLAG_SYSTEM_TIME

start

public void start()
           throws PortAudioException

Starts the stream. Also starts the parent stream if its not already started.

Throws:

PortAudioException - if an error occurs while starting this InputPortAudioStream

stop

public void stop()
          throws PortAudioException

Stops the stream. Also stops the parent if we are the last slave stream that use it.

Throws:

PortAudioException - if an error occurs while stopping this InputPortAudioStream
