Struggling with the 'ng' vs 'nang' distinction when listening to podcasts

I’m an immersion learner trying to move past subtitles, and the speed of native Tagalog content is really highlighting my gaps. Even when I listen closely, I can't tell if a speaker is using 'ng' as a marker or 'nang' for adverbs. Does anyone have a strategy for hearing this clearly, or should I use Chickytutor.com to have these specific audio clips broken down phonetically?
