I may be just dense or spacey but I can't stay tuned into audio. Tried repeatedly to learn things by audio and constantly have to rewind after floating off somewhere.
I do the same thing, depending on the situation...
sometimes I have several things going on and my mind is all over the place.
When walking, driving, or waiting in places like airports, Dr. office, etc., I love having audio learning tools.
When working, running, biking, or anything else active, it's a joke, most of the time.... but being a PPL student at this point, LiveATC was suggested by many, and it is something I will listen to even when being active, as I want the distraction to be a part of the learning process.
I miss a lot (usually because it's static-y, and some just seem to mumble at over 100mph. But I'm getting better as I go. Which I believe is a testament to the audio learning that we are discussing.
Another audio training that helped recently was a morse code app on my phone. It beeps out random letters and then reads them back. I learned morse code in about 2 days. I thought it would take me weeks! (I use Bluetooth earbuds...most older folks in the Dr. office are distracted by beeps that sound like irregular heart rate)
I'm a fan of having audio as a supplement to other forms of learning.
Of course it's limited in regards to things that need imagery, but being asked test questions would be great for me. My CFI does it on occasion, but I'd like it at my disposal while driving, riding, waiting, etc.
As corny as it sounds, with the Bluetooth headphones nowadays, even in the cockpit there might be some ideas for audio reinforcement via phone/tablet apps. Not saying depend on it, just have it as a supplement. I mean, it's pretty nice to flip a switch and listen to ATIS instead of having to read it, right, so why not other stuff?
Maybe audio checklist ?... listen to engine failure on takeoff procedures while on taxi? probably lot's of possibilities...and may be something I see as silly as I get more experienced, but being a new student I'd probably use some tools if available.
