Hello,
Yes, I'm ready to accept the fact that once the distortion is there on the master, it's not going away. I was just wondering if there was some kind of processing that could be done to reduce it. I tried "smoothing" it, and while it did reduce some of the distortion, it made it sound muddy like the azminuth needed adjusting during the transfer. I agree that the distortion on sample 1 isn't that bad, but it's very distinctive and occurs when both vocals and instruments reach a certain volume. The taper told me he tried to dial down the levels as best he could, but it came out like that. He seems to recall (the recording is from 1984) that the PA did not sound like that, so I'm pretty sure it was the mic overloading.
I did my best when recording sample 2. I stood all the way near the back of the room, but the bass was still overwhelming. The DV camera is fairly low end, so there was no way to adjust sound levels. The distortion only happens at certain low frequencies and only above certain volumes. I figured there still might be a way to notch filter it to dial it down if someone who has more experience than I do could isolate what frequencies it's coming from.
