How do I start learning about Audio Signal Processing?

Perhaps start by familiarizing yourself with Audacity’s included effects:

Starting in the '70’s I’m self taught as a graphic artist, musician, cartoonist, digital photographer and now audio enhancement or restoration of boomer pop music that sound thin on CD, no bass or stage presence due to poor mastering or mastered for vinyl and quickly ripped to CD’s during its heyday.

When I taught myself I had to ask questions specific to what I wanted to accomplish. For Audacity I got to know the preferences so playback in edits will sound as good and accurate when I save the baked in edits to the new CD file.

So my first question was “How do I make sure it sounds exactly as I would hear it when I edit and save the file”.

Start asking questions pertaining to what you want to accomplish. One question will lead to another to where you can Google them. The more specific the better the search results.

That’s the best advice I can offer. And BTW I was paid as a graphic artist and cartoonist back in the '80’s just on me teaching myself by asking the right questions on how to move forward. I have no degree in anything.

Goals are good. It’s a common problem that someone will post on the forum about a tool or process without ever mentioning the goal. Turns out the goal is best achieved with a different tool or process.

Audio Signal Processing, specifically, it’s applications in music.

Because? That’s not the goal. That’s the pathway to the goal. You want to hire out as someone who can rescue or sweeten a musical performance? You work for the US Library of Congress in their performance archive division? The music you’re performing and the music you hear in your head are really different and you want to make them match?

How are you listening? That’s another frequently ignored problem. One of the entertainment production companies has a musical “stinger” behind their logo that’s part 16 foot pipe organ tone. I bet fully 90% of the people who watch that have no idea it’s there because their sound system won’t do it. Knowing the tools and processes doesn’t do any good if you can’t hear what you did. It’s the musical equivalent of painting in the dark.
