Constructor Detail

StereoAudioInputStream

public StereoAudioInputStream(AudioInputStream input)

StereoAudioInputStream

public StereoAudioInputStream(AudioInputStream input,
                      int outputMode)

Parameters:

input - input

outputMode - as defined in AudioPlayer: STEREO, LEFT_ONLY or RIGHT_ONLY.

Method Detail

read

public int read(byte[] b,
       int off,
       int len)
         throws IOException

Reads up to a specified maximum number of bytes of data from the audio stream, putting them into the given byte array.

This method will always read an integral number of frames. If len does not specify an integral number of frames, a maximum of len - (len % frameSize) bytes will be read.

Overrides:

read in class AudioInputStream

Parameters:

b - the buffer into which the data is read

off - the offset, from the beginning of array b, at which the data will be written

len - the maximum number of bytes to read

Returns:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached

Throws:

IOException - if an input or output error occurs

See Also:

AudioInputStream.read(byte[]), AudioInputStream.read(), skip(long), available()

skip

public long skip(long n)
          throws IOException

Skips over and discards a specified number of bytes from this audio input stream.

Overrides:

skip in class AudioInputStream

Parameters:

n - the requested number of bytes to be skipped

Returns:

the actual number of bytes skipped

Throws:

IOException - if an input or output error occurs

See Also:

read(byte[], int, int), available()

available

public int available()
              throws IOException

Returns the maximum number of bytes that can be read (or skipped over) from this audio input stream without blocking. This limit applies only to the next invocation of a read or skip method for this audio input stream; the limit can vary each time these methods are invoked. Depending on the underlying stream,an IOException may be thrown if this stream is closed.

Overrides:

available in class AudioInputStream

Returns:

the number of bytes that can be read from this audio input stream without blocking

Throws:

IOException - if an input or output error occurs

See Also:

read(byte[], int, int), AudioInputStream.read(byte[]), AudioInputStream.read(), skip(long)

getFormat

public AudioFormat getFormat()

Overrides:

getFormat in class AudioInputStream
