eli5 what does “gain” mean in regards to audio and recording?

303 views

Basically just looking into external mics for my phone and all the reviews for the different products I’m looking at are talking about “too much gain” and “not enough gain” and I have no earthly idea what that means. I tried looking it up, but it’s confusing as hell for someone with no know, who just wants to record concerts to listen to again later

The programming in microphones will cut off certain frequencies or noise in order to get a clearer recording. “Gain” changes how much is filtered. With less gain only more pure tones are recorded. With more gain, you get the noise as well.
