I was wondering if there was any way to normalize only videos with audio that either have peaks that go above -5dB or peaks that are below -15dB.
I see many different types sources, and they should all peak at normal broadcast levels of around -10dB. Most of the videos come in with decent audio levels. Some unfortunately come in with levels that are either way too hot, or way too low. All of my processing is automated via batch scripts, so I'd like to automate this aspect also. I don't want to touch the audio levels of videos with decent broadcast levels. The ones that have levels that are way too hot or too low I'd like to bring back to -10dB.
I'm not sure if this is even possible or logical to normalize audio based on a threshold like this in avisynth... but I thought I'd try these forums to see. If there's another command line app (maybe BeSweet) that can do this to a wav file, that would also work just fine. Thanks for any help!
