Hello All -- I am brand new here, and nearly new to audio and video. I was a master control engineer years ago (worked my way through EE university), so I do understand some basics. Of course things are all different now! I hope this post doesn't break forum rules. I won't feel bad if it's moved or zapped as long as someone points me in the right direction. OK... I have been producing promotional and training videos for my astronomy automation software business. Here is an example. Despite using a decent AudioTechnica 2020 mic, I'm unhappy with the audio, so I have gone on a mission to learn how to fix up the dry audio and make it more professional sounding. This material is not going on to broadcast. It will be distributed via HD on YouTube (like the example above). Also, it will almost always be played on earbuds or computer speaker systems, rarely (if ever) on anything resembling a home theater system!! I have achieved some results, but my uneducated ear needs calibration from some experts. That's why I came here! I wonder if some of you would be OK with helping me by listening to a dry sample and then three processed samples and giving me feedback. The room has a couple of obvious resonances which I tried to minimize. I plan to try treating the room within the limits of my better half Also there is some background noise from a washing machine which was a "fact of life" this afternoon while making these test clips. It won't be running when I do the real thing. Here are the four 60-second samples on SoundCloud. I think it has blurred the differences, but then I assume YouTube will as well, so I thought this would work. I could upload them as little HD videos if you would rather (and I probably should do that anyway).
