Constructor Details

LameChannelStreamLine

public LameChannelStreamLine(WritableByteChannel bc,
 AudioFormat format,
 int brate,
 int quality,
 long writeAheadMillis,
 long timeoutMillis,
 int bufferSamples)
                      throws IOException,
UnsupportedAudioFileException

Constructs a line for encoding either native FLAC or Ogg FLAC.

Parameters:

bc - the channel to stream to, which must be non-blocking

format - audio format of the PCM data written to this line

brate - bitrate, kbps

quality - algorithm quality selection in Lame API

writeAheadMillis - limit for how much to write ahead of what receiver has played; use Long.MAX_VALUE for unlimited

timeoutMillis - time to wait when when write-ahead limit is reached

bufferSamples - size of line buffer in number of sample frames

Throws:

IOException

UnsupportedAudioFileException
