I didn't try the Perl builtin 'printf' as 'print' DID support terminal colours, so I made an assumption that 'printf' wouldn't plot either.
I will experiment with plotting using 'printf' and get back to you.
If I get stuck and plotting is still unable to be done then I will come back on here for solutions.
Well a cold start with the builtin 'print' DOES work but believe me, I tried for hours with hard coded valus as well is variables and I kept getting an major 'scalar' error report finally ending up saying it couldn't complie the code - hence reverting to the 'system' command.
I honestly do not know why I kept getting major errors when now it is working..
Here is the original test code i couldn't get working, but it is actually calling me a liar now.
And finally I am in the process of using 4 capture modes, DEMO, DSP, ALSA and QT, (DEMO is obviously working using the builtin random number generator but the final cut will create a raw 'noise' file using /dev/urandom).
I have already done the section to create the AppleScript and call it, but not done the binary file to byte sized decmial array or list yet but I am working on it...

Reason: See EDIT:
Modified greatly and now captures real bytes from '/dev/urandom' and displays the plots.
Removed system() function calls where possible, (compare with post #1).
Saves a 'config' file to the current directory and loads on program restart, it just saves the capture mode on quitting at the moment.
As this is just an exercise in me learning the basics of Perl then this will not go anywhere near as sophisticated as AudioScope[.sh].
It is also ONLY capturing 64 bytes and running at maximum speed of 1mS per division as this is just a personal learning exercise.
Commented out the RANDOM line for the vertical axis FTTB.
Results before quitting:
All criticism welcome!

I've been having problems with audio, at first I experienced the basic problem that was solved by adding pulse audio to the starting programs. This allowed me to open Sound preferences but I still have no sound.... (0 Replies)
I want to save a song which is being played from internet.
I cant find where it gets cached. Im also not sure if the whole sing will remain in the cache while the song finishes.
There must be a way using /dev/audio or something. Im not able to figure out. (4 Replies)
