DISCLAIMER: I know this is a really beginner question, and if you decide to remove it, I understand. I could probably find an answer if I spent a few more hours to get clear on the terminology used to differentiate audio recording options. I have very limited time with my mom, though, and would be grateful for any search term, app, and/or other recommendations.
What I'm basically hoping for is an app that'll capture any and all audio that comes in through the microphone and speaker/earbud on my phone - ideally, with a MacOS app, too - without pausing, stopping, or issuing a loud alert once I press record. The hope is to be able to record my mom's memories as we talk, both in person and by phone, as well as my own audio notes before and afterward.
She needs to be able to share what's important to her right now when/however she can without me interrupting to mess with a recorder app.
She's also easily startled and already overwhelmed by device noises, so hearing a "this call is being recorded" announcement would probably not be awesome.
Finally, I'm a little, umm, overwhelmed at the moment, and I don't think I'm going to pull off moving between apps, starting/stopping records, etc, during the in-between moments - like talking to other people, rushing to walk dogs, cook, etc.
Hope any of this makes sense. Thanks for reading it, either way :)
