Method Detail

skip

public void skip(long bytesToSkip)
          throws java.io.IOException

Specified by:

skip in interface TarsosDSPAudioInputStream

Throws:

java.io.IOException

read

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

Description copied from interface: TarsosDSPAudioInputStream

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.

Specified by:

read in interface TarsosDSPAudioInputStream

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:

java.io.IOException - if an input or output error occurs

close

public void close()
           throws java.io.IOException

Description copied from interface: TarsosDSPAudioInputStream

Closes this audio input stream and releases any system resources associated with the stream.

Specified by:

close in interface TarsosDSPAudioInputStream

Throws:

java.io.IOException - if an input or output error occurs

getFrameLength

public long getFrameLength()

Specified by:

getFrameLength in interface TarsosDSPAudioInputStream

getFormat

public TarsosDSPAudioFormat getFormat()

Specified by:

toAudioFormat

public static javax.sound.sampled.AudioFormat toAudioFormat(TarsosDSPAudioFormat format)

Converts a TarsosDSPAudioFormat to a AudioFormat.

Parameters:

format - The TarsosDSPAudioFormat

Returns:

A AudioFormat
