Hi list!
From what I've recently learn, audible tones (DTMF tones I've been
told, although I recalled DTMF acronym to be telephony related...) in
radio networks, due to its simplicity and, more importantly, low cost
(drop satellites!) are becoming somehow by paradox (I've been told that
for years, DTMF tones where considered a matter of
amateur/non-profit/tiny radios... being satellites used for the 'pros')
the preferred way to trigger events here (Spain)... Even top-tier,
nation-wide radio networks, have switched to audible tones (I had not
realized about that, but now, paying attention, I hear them!) and have
dropped satellite signaling costs.
This triggered me a question immediatelly: On Windows-based automation
systems, DTMF detection uses to be included as a feature, so... how does
the Rivendell community users handle this!?!?!?!
Googling around, I've found this:
http://wiki.rivendellaudio.org/index.php/How_to_trigger_events_from_tones_on_your_network
Although somehow old, and basically pointing to the usage of a Windows
software under Wine, that tells me that the need, the use-case, is
there... and has been dealt by someone.
I've also found references for some linux tools, like multimon and
multimon-ng, even Node/NPM libraries, being able to detect audio tones
under Linux, but not much user-friendly... so:
How do you handle this? What are your approaches to handle DTMF and
trigger RMLs... Wouldn't be nice to have RDCatch to be able to 'catch'
tones?
Cheers
