For me, I'll usually start through repetitive listening (if time allows)
I have 1 1/2 + commute time - usually and easy drive.
Having a trained ear and being able to pick out intervals and patterns helps, along with humming or singing the part. (best done alone in a car)
From there, technology has given more options over time.
I'll create playlists, these days on Spotify.
I've found a lot of isolated bass tracks on youtube (which can be an eye/ear-opener sometimes)
Sometimes, I'll also find notation for a lot of songs online.
I had to brush up on Moondance a couple years ago. It was helpful following the notation while playing along - not that you'd play it live that way, but it sped up the "refresh" process, and helped pick out key patterns & parts that I would want to incorporate.
The best way for me to commit to memory is the process of writing it down;
I have my own bastardized shorthand for basic cord progressions or key changes, and sometimes notate specific riff or patterns; No one else could likely make sense of my written method...
I picked up the Boss Waza last year. It's the best system I've ever had for this purpose.
When I'm just "noodling", I play my bass through an amp all the time, and it's "tolerable" for my wife.
But when I'm doing a deep dive into learning a song, repeating key sections or riffs, well, nobody wants to hear that!
And you can control the "mix" much better. I have a habit of playing what I "think" I hear or anticipate, rather than the part itself, and if you're too loud, you won't notice what you're doing. Finding the right level / mix and being able to hear both clearly is very helpful)
