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

295 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

Gain refers to how much signal the microphone picks up.

High gain means it will detect more sound (in a wider area around the mic) but also increase the chance of audio feedback.

Low gain means you have less chance of feedback, but some sounds may not register in the mic (or in a smaller area around the mic)
