[Freeswitch-users] Noise Detection

[Yisroel M. Olewski]

Hi

Thanks a lot

Putting into a conference certainly helped (im also working on this project)

The problem is it seems that after about 4-5 custom events with an energy level, it stops sending events

I can’t figure out why

In the profile I set the noiselevel to 0 or 50 just very low, but it makes no difference

Something else is interesting, that as soon as I press any digit on the phone it somewhat “comes to life” again and  I get some more energy levels

Since this is for a house monitor, it’s important to get steady events for hours on end

Please advise

Thanks a million!

 

Sincerely,

I guess arduino will do a better job here, and you have a choice of all kinds of sensors: noise, motion, brightness, infrared, smoke, door switches, temperature and humidity.

You might want to check out using a conference. The mod_conference module can emit a number of different events, including start talking and stop talking events. I would recommend that you add the channel to a conference room and then monitor the conference::maintenance events as sound is received on the channel.

If it works then you might even be able to have multiple conference members for different areas of the house. That could possibly let you narrow down where in the house the noise is occurring by observing which conference member is 'talking.'

hi everyone


im trying to implement noise detection in freeswitch (as a house-monitoring system)

id like to know when any noise occurs on the line so it can alert me by email etc.

ive done the following settings

 

                        SwitchExecute("set", "fire_talk_events=true", swchEvnt.ChannelCallUUID)

                        SwitchExecute("set", "rtp_enable_vad_in=true", swchEvnt.ChannelCallUUID)

 

(SwitchExecute just calls esl.Execute)

 

i am getting "Talk" events in  my log, but they do not seem to be related in any way to actual noise. maybe random, maybe when i press a dtmf (seems to be generating talk events)

 

in any case, talking to the phone does not generate any talk events

 

i am not setting vad=both or anything like that since i do not want the phone to disconnect or something upon silence. or did i get this wrong?

 

any ideas?

 

additional, id like it to generate events on any noise, not specifically human voice speaking
