[Csnd] New UDO: go all EuroSignal :)

Hey hey,
I have just put together a little UDO that encodes numbers into EuroSignal. EuroSignal was an old paging system up to 1997. It played special tone patterns on the low ultra shortwave band around 87.3-87.4 MHz. You could hear these earie unmelodic tone sequences on normal radios, if you went completely to the left of the scale.

For the longest time I had mistaken these tones for something to do with emergency services radio. -- Anyway: it comes with a UDO and a demo file. It's dead easy to use and written according to the specification as found on Wikipedia. A link is included in the UDO.

This is on Dropbox, so will vanish after a while. I'm still in the process of reorganising miscellaneous Csound code into a permanent form.

Best wishes and enjoy,

Jeanette

Jeanette,

Love it. Thanks for the design. Thanks for the UDO. Thanks for sharing. Cool and fun and inspiring, too!

Hi Richard,
many thanks for the feedback. I'm glad you enjoyed it. A bit of local holiday fun and self-therapy. :slight_smile:

Best wishes,
