Hello,
I just found this nice project.
http://www.mcselec.com/index.php?option=com_content&task=view&id=71&Itemid=57
I already built something like that using the Sanyo LB1412 IC
but this part has become obsolete... (there's only a smd version available but it's obviously very hard to get)
so I think it's better to look for another design.
I don't want to use the lm391xseries because they don't have this nice peak hold feature.
I'm not so familiar with atmel based designs, so I've got a few questions.
What extra circuitry is needed to get it work? I think I'll need a 10mhz crystal and +5V power supply... is that all...??
I think I have to rectify the audio signal before I apply it to the input of the microprocessor. Should I use a half wave or full wave rectifier...?
thanks,
matthias
