Hi, I’ve learned Audacity to improve audio for a project management course, and have applied 100 Mhz hum removal, normalization, de-clicker, and some tempo improvement.
The audio is much better, but still sounds “weak” to me. This might be an unfixable feature of the narrator However, audacity has so much power, I am wondering if there are other things that can be done. Could those with expertise with Audacity give a listen to the following, and provide your advice on what other processing would be recommended to improve it?
There’s no MHz in audio. Power line hum is 50Hz or 60Hz, depending won where you live, and related harmonics (multiples of the power line frequency). A 100Hz high-pass filter will reduce everything below 100Hz, so if that’s what you did, fine.
Normalization uses the highest peak in the file for it’s reference, so if you’ve got one “loud” spot that will limit any increase you might get from normalization. You can try the Limiter, set to Hard Limit with make-up gain (It’s the make-up that actually makes it louder, after limiting). Maybe try limiting to -6dB, and if that’s not enough run it again.
Nope. Not here. I hear someone with little or no experience reading, but it doesn’t seem to be broken. Listen on a different device or computer.
That’s theatrical presentation—acting. Instructional presentation isn’t just slowing down. Here’s your clip contrasted with a CGP Gray instructional video track (attached). He is cheating. He’s carefully slicing off the interstitial bumps between sentences, but nobody said you have to mirror real, live reading (except ACX AudioBook).
That’s not to say you can’t edit your material and have it come out almost perfect. It can’t take more than a couple of months for the first segment or two. You should without question get the performer to do this. Nothing spurs self-correction faster than having to clean up your own bad reading.
Of course, if he’s paying you enormous sums of money, leave the arrangement the way it is.
