It seems to be possible to hear the sound of execution of a Java software; CodeSounding assigns instruments / pitches to programming statements (if, for, etc), so that the flowing of execution can be played as a flow of music.
Max/MSP enabled the auralization of several sorting algorithm’s execution path: every instruction triggers an oscillator, tuned to a specific pitch.
