Passing audio through opto isolator? What is input and output component, which would work as audio speed?Hi again,
I intended to make one for the TV because of those pesky, loud commercials, but didnt get to it yet.
I got a couple of those linear opto isolators for the job, the ones with the purely resistive output element. They would be ideal for audio but i havent checked to see if the response is too slow or not yet.
Your results may vary, but - most TV commercials are not louder because the peaks are larger, but because the audio is heavily processed and compressed (Audimax, Volumax, etc.). A peak-detecting compressor/limiter probably will not do much.I intended to make one for the TV because of those pesky, loud commercials, but didnt get to it yet.

I wish I had that part 40-45 years ago. It would have made my life better.VTL5C4
A "drawback" of digital audio is that there is about 30 dB of extra dynamic range to play with. I'm sure whispers drew you into a sense of shared intimacy - in the mix booth.I also notice lately in movies there are a lot of soft passages too where the actors are talking and i cant hear them because they are whispering a little. That's annoying too.
I notice that today many people who are speaking end each sentence with a growl. Either they run out of breath and do not take in more air or they don't care if their voice stops before they are finished talking.
My Sound Level project has a microphone and a bar graph. It shows that the peak levels of TV programs and commercials are the same but the average level of commercials is much higher because they have too much compression.
