Title: MusGraph
Post by: MGOS on January 14, 2012, 06:12:02 am

This is my first implementation of an idea a friend of mine had after I showed him my axe TIstudio (http://ourl.ca/14703).

It graphs any function with any window settings (like the OS), but it plays a note to each corresponding Y-value it draws.

How to use it:

• Put "MUSGRAPH.8xp" (TI-Basic) and "MUSGPLAY.8xp" (ASM) on your calculator and plug 2.5 mm headphones or amplifier in.
• Press [  Y=  ] and enter any function want to hear/graph
• Press [WINDOW] and enter the maximums and minimums
• Press [ PRGM ] , chose "MUSGRAPH" and press [ENTER] two times
• A text which says "Generate... " and a progress bar will appear, then it draws and plays the graph

Issues known:
Functions with nonreal Y-value in the given range (e. g. sqrt(X)) will throw an error.
Also, only the standard Y= functions will work, no parametric or polar.

Attached files:

TI-Basic executable: MUSGRAPH.8xp (main program, execute this)
Asm sound routine: MUSGPLAY.8xp (needs to be on the calculator, but do not execute!)
Axe source code: AMUSG.8xp (not needed, only for people who want to know how it works, compilable with AXE 1.0 or higher)

Well... nice concept but it may not produce very exiting melodies. I'll try it anyway. Does it work with parametric functions ?

Not yet.

It is just a fun project, nothing serious so don't expect anything outstanding.

I tested it and it's quite fun. You can get some nice results with decreasing cosinus or sinus. ^^

X*sin(X+cos(X)) and 10*abs(sin(X+.5*cos(X)))-abs(X) are quite interesting too (Window: Zstandard)

Yay, now we can have a quadratic solver that plays music while finding your roots! :D

Nice job. Now let's go and find the most interesting graph to play.

Lol, I am going to try this on Wabbit, sounds fun :P
