Re: Where to start with remastering/cleaning audio? (Need help)
The one thing you'll need most is willingness to experiment. And patience - you can't learn it overnight or by following a simple guide, and several tasks rely on brute force manual wok.
You need to know which problems can occur with old audio sources, how to spot them and how to ameliorate or fix them. You need to look at the audio samples (audacity is good enough for that), and become familiar with a good spectral editor like Izotope RX.
It is easy to slap on some NR and repitch something, but if you do so without consideration, you're not doing any good. That's the pinkrobert way of remastering, and it is rightly outlawed. It's not that all remastering is entirely bad and evil (which is the ridiculous attitude presented on this forum), but you have to decide what each source needs. If you take great care, you can really work miracles with bad sources.
Non-inclusive list of issues, roughly in ascending order of difficulty:
- EQ
- phase mismatch / azimuth
- hiss / noise
- dropouts
- clipping
- distortion
- speed issues, wow & flutter
