javax.media.format.AudioFormat
sun.com/products/java-media/jmf/2.1.1/apidocs/javax/media/format/AudioFormat.html" target="_blank">this class in the JMF Javadoc. Coding complete. Frame size/rate: for linear formats this will generally be the sample size/rate * the number of channels. For compressed formats this will be the size of the "frames", which is completely codec dependent. And the Frame rate is similarly the rate for these frames. @author Ken Larson
