I would suggest you start with reading "Signal Processing and Linear Systems" by Lathi (great book, had it on a course) so that you gain some understanding on signal processing. After understanding filters, and frequency analysis, you will be able to ask more specific questions…
on “Ask HN: How do I go about audio background noise removal?” ↗+1 Great book. Although it can be a bit handwavey and a bit light on the math. Honestly I think it's best supplemented with a good signals and systems text. I like "Signal Processing and Linear Systems" by Lathi and "Digital Signal Processing : principles, algorithms and applications" by Proakis.
on “An Interactive Guide to the Fourier Transform” ↗Just today, I went back to one of my old textbooks (Lathi's Signal Processing and Linear Systems) and came out with some really important points about Fourier analysis that I'd missed the first time around. A good, carefully written textbook makes hard choices about context, sequence, presentation,…
