Method Detail

writeSamples

public void writeSamples(java.nio.ByteBuffer[] channelBuffers,
                         int nframes)
                  throws java.io.IOException

Writes samples from specified buffers to the WAV file.

Buffers in the given array are used for corresponding channels. If the array element at index i is null, the channel i will be filled with 0db samples. If the array has less elements than the number of channels, channels with higher numbers will be all filled with 0db samples. If the array has more elements than the number of channels, extra buffers will be ignored.

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Closes the file.

This method must be called after the last sample is written. The instance is unusable afterwards.

Throws:

java.io.IOException
