It is not known if this is correct, but the settings can be changed. The application has been set to play the disk clockwise with the low notes at the outside of the disk. There are 61 notes on the disk but only 47 MIDI notes, so the 61 have been compressed to 47.

Imported as a bitmap, the software scans the digital tracks and analog sectors and converts the perforations into MIDI notes according to the midiRamp() function.

We also do not know the code for matching a hole with a note.Ī century-old steel compact disk was photographed and the photo converted to black or white using the threshold function. The tracking is off and the image is distorted. Some of the sound effects are similar to those generated by the early computer games. In Windows XP it is sent through the primmitive 2' speaker inside (and is not subject to volume control) the box and produces a more mechanical and raspier tone. In Windows7 it appears to be sent through the system sound card, producing a softer tone, limiting its range and limiting its speed of execution. Beep() works differently in Windows7 and in WindowsXP. Each call to beepRamp() produces a sharp spike or click at the beginning of the note, This is sometimes louder than the note itself and and for short note durations, can be disturbing. Although beepRamp() does not offer the range of voices available in midiRamp(), the sound envelope it produces is unique. The derived beepRamp() function allocates 100 notes to the scale, and in that sense it is more finely grained than the midiRamp(whole, part, milliseconds) function. This application explores the primitive Windows function Beep(hertz, milliseconds) in an effort to construct a beepRamp(part, whole, milliseconds) function which can be used to sonify a data set.
