[CM] Snd with alsa and jack, flac conversion, motif/gtk

[Bill Schottstaedt]

Here's a plausible flac file opener:

(load "examp.scm")
(define mus-flac 64)
(hook-push open-hook
           (lambda (hook)
	     (let ((filename (hook 'name)))
	       (if (= (mus-sound-header-type filename) mus-flac)
		   (read-flac filename)))))

Load that into Snd before calling open-sound.

I don't know.

You can open a new sound, then write its data directly, updating the
graphs each time you get new data.  But in the FLAC case, unless you
write code to read directly the output of flac, you'll need a file.

Wow.  The Debian version I have has gtk 3 which makes Snd look like crap.
gtk3 changes so often and so radically that I've stopped trying to
keep up. I doubt their Motif package is any more usable than their 
Snd package.  Someday I'll move to Juce...

On an optimistic note, gtk has finally added openGL support, but I can't
immediately see a way to use it in Snd without keeping two parallel
drawing widgets going all the time for each channel.
