I have been copying reel to reel's of my great uncles band to the computer. Aside from a bit of degradation from being played many times and stored for about 70 years, my grandma was sitting a little too close to the bass amp when she recorded the live shows. My question is two-fold. 1- I read somewhere that the Library of Congress uses heat (about 130°F?) to recover degraded reels. The reels are not shedding oxide yet. Is this technique real, and does anyone have enough experience using it to give me some advice? 2- Some of this distortion is from over-driving the microphone. I was wondering if it is possible to repair that. I sort of envisioned using Goldwave to separate the different frequency components and pass the low ones through a filter and reassembling the audio. I figure this will be difficult with the variation of bass tones and the harmonics created by the flat topping, and I fear this will only work if done one chord at a time, if at all. Again, looking for some direction because these recordings mean everything to my grandmother and they are the only ones known to exist. Thanks!
