public class PlaybackPlot
- extends java.lang.Object
Receives a plot and a decoder and plays back the audio from the decoder at
the same time as it sets the marker in the plot accordingly. The marker
position is calculated in pixels by measuring the elapsed time between the
start of the playback and the current time. The elapsed time is then
multiplied by the frequency divided by the sample window size (1024 samples
in this case). This gives us the x-coordinate of the marker in the plot.
After writting a sample window to the audio device and setting the marker we
sleep for 20ms to give the Swing GUI thread time to repaint the plot with the
updated marker position.
