[Discuss] Digital tone generator.

[chris wakefield]

Evening all.

I'm trying to find a current name for an application that will generate simple 
musical tones.  I'm a singer, and I'd like to hear a "A" every once and a 
while.  I would call it a:  "Sound or tone generator"

I don't want to have to load a file of any sort, or learn another 
*undocumented* command line option <hours on Google>

I'm finding that there are many applications out there in Debian land, for 
example, that have the word "Sound" in them, and it's a vast list.

I would like to simply click a button, or just:  
~$binary --pitch A --duration 10

Does anyone know of such a program, or even a source compileable on X86_64?

Thanks,
Chris W.
