Use case or problem
m4a audio format happen to be extremely space taking. A simple audio for 3-5 minutes can take up to 8mb! Imagine having like 100+ recordings a day, I managed to have 1,3gb just after 3 days! As any other user I value my phone space, and it is extremely disappointing that my number one note taking app still doesn’t have anything better than that.
I noticed that even the audio quality is way worse when recording to m4a compared to mp3 or ogg.
Proposed solution
It would be really helpful to expand or completely change the format audio notes are taken. My proposal is to add options such as ogg or other less space taking format. It will right away skyrocket the experience of using Obsidian and make it even more handy.
