GREAT, GREAT, GREAT !!! Thanks a lot !!!djsoft said:
Hi,
I am using DTMF since it has been released and I am planning using it even more intensively.
I would like to have more information in order to get a reliable detection and to try to hide from listeners the DTMF tones has much as possible.
I notice that during normal playback DTMF digits are regularly detected in the music, I also notice that occasionally the DTMF code is not detected by RB hense the associated task not started.
Could you please publish some best practice?
Here are a few questions I can think of.
What is the recommended number of digits to use?
Is it necessary to have a blank before the first digit, after the last one and between two digits?
What are the recommended digit duration and the ratio with blanks between digits? ie 40ms digits separated by 20ms blank.
Is detection only on left channel?
What is the recommended audio level for digit? What is the signal ratio between digits and background music? And what is the recommended value for the RB DTMF level detection setting?
Could the DTFM checker and the RB debug info window display some king of quality detection when detecting DTMF?
Regards
Christian

Christian, currently there are no best-practice settings I can post...
The interval between digits should be about 45ms, the tone durartion should be at least 50 ms - this is for reliable detection. You can try varying those lengths to see how it works. In most cases stations use 4 digits.
The level depends on the signal level... The lower you set it - the more false-detected tones (eg. from the music) there will be. This value should be set experimentally.
RB can't display quality, it either detects a tone or not... The quality measurement here is how many false detections you get.

so I have to play the tone from my computer to get the event to run, I dont get it how could this be useful ? I read the manual, didnt get it though, if there is more information.
I read the manual and the commands, but how to apply them ? assume I am home now, how can I send these commands to my work's RadioBoss ?
Usually DTMF is used when you rebroadcast another station and insert your own (e.g. local) ads. It's not intended for remote control.moh001 said:
All the commands are sent using HTTP requests. You can use web browser, just put the request in the address bar. There are examples in the documentation, try them.moh001 said:
