Run & Gun audio when making video is very different than working in a recording studio

Its been way too long since I've been here.  The new forum looks great.  I have settled in to my new business of creating videos for clients and my business needs to become a client as well:) So I've started a youtube channel about all nerd things video👍

Greetings. I'm looking for a filter or tool that can remove the music from a live video source (e.g., a NASA broadcast), while leaving the voices and non-musical noises. It doesn't have to be perfect, but it needs to remove/mute enough of the music to avoid triggering YouTube's copyright detection, and not mess up the voices too much.

Here is a link to teaser for a mini documentary that I finished for a client (The town where I live and run my business in). I'll share the full mini-doc when it is released Tuesday. There were several audio challenges. The mini-doc gave three musicians employment and my consulting company work.

I am recently retired (mostly) and living in a rural community in Nova Scotia. We have/had a very active arts scene that punched far above our demographic, drawing audiences from ~150kms. All indoor venues are small (50~200 seats) but manage a few outdoor festivals each year that attract 500~5,000.

I thought I'd like to kick of this new forum category with some lessons I've learned in over the last few years in video production and I would love to hear others views.

My top 3 myths are:

1. All you need is a smartphone and you can make awesome videos.

Hey everyone,

Which remote preamp in front of audio inputs for dSLR video?
