Can I fix choppy (like buffered) audio?

I found an old song file I want to work on, but somehow in getting it from my phone to my laptop to my Mac, it ended up skipping 5x every second, like it was a bad buffer. I had to slow the speed to 50%, but hope to find a way to remove all the blank audio portions without going second by second manually. I’ve attached a screenshot of what it looks like. That’s what the whole song looks like. I can delete the blank portions and it sounds just fine and normal, but don’t want to have to go through and delete all 1800 spots.

You could use “Truncate Silence” https://manual.audacityteam.org/man/truncate_silence.html

The “Action” setting will need to be “Truncate” rather than “Compress”, and set “Truncate to: 0”.
You will need to adjust the other settings to suit the audio.
