Clip

Fields Summary
public static final int	LOOP_CONTINUOUSLY A value indicating that looping should continue indefinitely rather than complete after a specific number of loops.

Constructors Summary

Methods Summary
public int	getFrameLength() Obtains the media length in sample frames. return the media length, expressed in sample frames, or AudioSystem.NOT_SPECIFIED if the line is not open. see AudioSystem#NOT_SPECIFIED
public long	getMicrosecondLength() Obtains the media duration in microseconds return the media duration, expressed in microseconds, or AudioSystem.NOT_SPECIFIED if the line is not open. see AudioSystem#NOT_SPECIFIED
public void	loop(int count) Starts looping playback from the current position. Playback will continue to the loop's end point, then loop back to the loop start point count times, and finally continue playback to the end of the clip. If the current position when this method is invoked is greater than the loop end point, playback simply continues to the end of the clip without looping. A count value of 0 indicates that any current looping should cease and playback should continue to the end of the clip. The behavior is undefined when this method is invoked with any other value during a loop operation. If playback is stopped during looping, the current loop status is cleared; the behavior of subsequent loop and start requests is not affected by an interrupted loop operation. param count the number of times playback should loop back from the loop's end position to the loop's start position, or {@link #LOOP_CONTINUOUSLY} to indicate that looping should continue until interrupted
public void	open(javax.sound.sampled.AudioFormat format, byte[] data, int offset, int bufferSize) Opens the clip, meaning that it should acquire any required system resources and become operational. The clip is opened with the format and audio data indicated. If this operation succeeds, the line is marked as open and an {@link LineEvent.Type#OPEN OPEN} event is dispatched to the line's listeners. Invoking this method on a line which is already open is illegal and may result in an IllegalStateException. Note that some lines, once closed, cannot be reopened. Attempts to reopen such a line will always result in a {@link LineUnavailableException}. param format the format of the supplied audio data param data a byte array containing audio data to load into the clip param offset the point at which to start copying, expressed in bytes from the beginning of the array param bufferSize the number of bytes of data to load into the clip from the array. throws LineUnavailableException if the line cannot be opened due to resource restrictions throws IllegalArgumentException if the buffer size does not represent an integral number of sample frames, or if format is not fully specified or invalid throws IllegalStateException if the line is already open throws SecurityException if the line cannot be opened due to security restrictions see #close see #isOpen see LineListener
public void	open(javax.sound.sampled.AudioInputStream stream) Opens the clip with the format and audio data present in the provided audio input stream. Opening a clip means that it should acquire any required system resources and become operational. If this operation input stream. If this operation succeeds, the line is marked open and an {@link LineEvent.Type#OPEN OPEN} event is dispatched to the line's listeners. Invoking this method on a line which is already open is illegal and may result in an IllegalStateException. Note that some lines, once closed, cannot be reopened. Attempts to reopen such a line will always result in a {@link LineUnavailableException}. param stream an audio input stream from which audio data will be read into the clip throws LineUnavailableException if the line cannot be opened due to resource restrictions throws IOException if an I/O exception occurs during reading of the stream throws IllegalArgumentException if the stream's audio format is not fully specified or invalid throws IllegalStateException if the line is already open throws SecurityException if the line cannot be opened due to security restrictions see #close see #isOpen see LineListener
public void	setFramePosition(int frames) Sets the media position in sample frames. The position is zero-based; the first frame is frame number zero. When the clip begins playing the next time, it will start by playing the frame at this position. To obtain the current position in sample frames, use the {@link DataLine#getFramePosition getFramePosition} method of DataLine. param frames the desired new media position, expressed in sample frames
public void	setLoopPoints(int start, int end) Sets the first and last sample frames that will be played in the loop. The ending point must be greater than or equal to the starting point, and both must fall within the the size of the loaded media. A value of 0 for the starting point means the beginning of the loaded media. Similarly, a value of -1 for the ending point indicates the last frame of the media. param start the loop's starting position, in sample frames (zero-based) param end the loop's ending position, in sample frames (zero-based), or -1 to indicate the final frame throws IllegalArgumentException if the requested loop points cannot be set, usually because one or both falls outside the media's duration or because the ending point is before the starting point
public void	setMicrosecondPosition(long microseconds) Sets the media position in microseconds. When the clip begins playing the next time, it will start at this position. The level of precision is not guaranteed. For example, an implementation might calculate the microsecond position from the current frame position and the audio sample frame rate. The precision in microseconds would then be limited to the number of microseconds per sample frame. To obtain the current position in microseconds, use the {@link DataLine#getMicrosecondPosition getMicrosecondPosition} method of DataLine. param microseconds the desired new media position, expressed in microseconds
