Hello,

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
