Timer function

Hi,

I plan to write a software metronome and I wonder what would be the best
way to get a timer precise enough for that purpose ?

The other problem is what's the best way to make a short sound
(eventually corresponding to a note ...)

Thanks for your help.

Fred

I wrote one using just g_timeout_add(), and that seems to me to work
well enough.

I've put the source code up at
http://www.ossau.uklinux.net/guile/metronome.scm, in case you'd like
to look and don't mind reading Scheme.

Indeed. I don't have a solution for this yet; would be interested to
hear if you find a nice one. Currently my metronome is just visual.

Regards,
Neil

hi,

I work on a whole music composer [1] built on gstreamer and there you can use
gst-controller to trigger notes or change sound-parameters. GStreamer cares
about the timing, you just schedule changes with a timestamp. Come to #gstreamer
irc on freenode.org if you have questions.
