Posted on April 21, 2015 at 17:23Hello,
I want to save between 1 and 5 noises or sounds as reference, whenever;
Nr1 noise is played (source can be input of speakers) the relay needs to be switched 1 time
Nr2 noise is played (source can be input of speakers) the relay needs to be switched 2 times
Nr3 noise is played (source can be input of speakers) the relay needs to be switched 3 times
Nr4 noise is played (source can be input of speakers) the relay needs to be switched 4 times
Nr5 noise is played (source can be input of speakers) the relay needs to be switched 5 times
I dont want to use microphone as transduser because the enviroment is very noisy. I need to gather the analogue sound signal from the inputs of the speakers.
I cannot use PC or OS based programs.
Any ideas what is the best solution?
Many thanks
Best Regards
Alkan
