Can anyone give me any info on the following.  I'd be interested if anyone
builds such a thing or if anyone can provide a diagram.  What i'm looking
for is some kind of audible vu meter or level indicater.  I'd like
something I could use in the line input jacks of my recorder or cd
recorder.  Something that would let me set a reference and if the signal
went in the red or above this point it would beep or something.  I thought
years ago s f b made such a thing, but can't remember.  Open to any advise
or suggestions.
