Class SampleQueueInputStream

java.lang.Object

      com.softsynth.jsyn.util.SampleQueueInputStream

public class SampleQueueInputStream
extends SampleQueueStream

Adds streaming read capabilities to a SynthSampleQueue. The queue must be on a unit that will write data to the queue such as a SampleWriter_16F1. The SampleWriter will write data to the sample that is then read by this stream via the queue.

Constructor Detail

SampleQueueInputStream

public SampleQueueInputStream(SynthSampleQueue queue,
                              int bufferSizeInFrames,
                              int channelsPerFrame)

Method Detail

start

public void start(int time)

Overrides:

start in class SampleQueueStream

getOverflowed

public boolean getOverflowed()

Return true if the buffer has overflowed and data has been lost. To prevent this, use a larger buffer, or read the data more often.

read

public int read(short[] data,
                int offset,
                int numFrames)

Read an array of short data from sample. If there is not enough data available, block until all of the data can be read. To avoid blocking, call available() first to see how much can be read without blocking.

Parameters:

data - Array of shorts containing PCM sample data

offset - index of array to start reading data from

numFrames - number of frames to read from sample

Returns:

number of frames read
