This sketch is an example of how to use the size method of an AudioBuffer to get the size of one of an AudioSource's sample buffers. The classes in Minim that extend AudioSource and therefore inherit the left, right, and mix buffers of that class, are AudioInput, AudioOutput, AudioSample, and AudioPlayer. Not coincidentally, these are also all of the classes in Minim that are Recordable.

The value returned by size is the number of samples stored in the buffer. It will always be equal to the bufferSize() of the Recordable you are working with. It is often a value that you specify when you create the Recordable such as with loadFile or getLineIn.
