sound software

Sound by Canadian Mind Products

Sound lets you mathematically create sounds in Java. You define your sounds in terms of 16-bit linear code for the waveform, -- an array of samplings. The U_Law.class will then convert that to (or from) *.AU mu-law 8-bit encoding format which you can then play with AudioPlayer.player.start(bis) in an application or with Applet.getAudioClip in an Applet. This is just a sample program. You would insert your own mathematical functions.

DISGCL PostScript Manual by MPI fuer Sonnensystemforschung

The program DISGCL is an interpreter based on the data plotting library DISLIN. DISLIN statements can be written to a script file and then be executed with DISGCL, or can be entered in an interactive mode. Similar to programming languages such as Fortran and C, high-level language elements can be used. These are variables, operators, expressions, array operations, loops, if and switch statements, user-defined functions and I/O routines.
