This is Whistle Calculator running as an applet. It demonstrates the core functionality of the program. The full functionality (for example load and save) can only be used when the 'stand-alone' application is downloaded and run. This is not some evil scheme to get my code onto your machine, but a feature of Java's 'sand box' philosophy of protecting your computer from potentially harmful code on the web.

I would like to thank

Pete Kosel for allowing me to use the algorithm from Flutomat
Daniel Bingamon for allowing me to use the algorithm from TWCalc
Hans Bracker for his patience and support through many useful discussions.

New in Version 2.04:

Version 2.04 is mainly a maintenance release:

A bug was fixed in the calculation of cut-off ratios for thumb-holes.
The interface has been tidied.
.The three-dimensional whistle has been replaced with a simpler, clearer line drawing. The options to zoom and rotate have gone. The associated controls for specifying offsets have gone. This helps to clarify the display.
