Earlier this year my brother came across some records my grandmother made back the 40s. We plan to make them into a CD to give to her for her birthday. We've been able to capture the sound into WAV files, but there is a large amount of static (as expected since these are old records). I've tried using noise removal in Audacity but I get this weird distorted scratching effect. Any experts know how to fix this? I can put up a sample of both if needed.
