I'm going to state upfront that when it comes to audio, I'm a complete novice. I transfer home videos to DVD (camcorder recordings, not commercial movies...) as my full time business. I use a hardware video processor to correct minor video problems (noise, color, black level, etc...) and then feed the video signal into a time base corrector. This works great on the video end, but I sometimes receive tapes that have poor audio. With my current set-up I have to fix any audio problems (low sound, high frequency hiss, etc...) with software, which adds quite a bit of time. In my ongoing efforts to increase efficiency I have been wondering if there is a hardware equivalent I could be using instead. It would sure save a lot of time to be able to "fix" audio in real time instead of demuxing the audio from the video, processing it, remuxing, etc.
Does anyone know what kind of equipment I could use for this? If something is available it would need to be able to accept regular RCA audio cables since that is what all of my other equipment uses.
