Why does captured audio on mobile have really low quality?

The audio recorder on Logseq’s mobile app captures sounds at a noticeably low quality. Regular sound recorder apps installed on my device sound MUCH better.

Is there an option to choose the quality? If not, is this normal? What’s the default Kbps?

Also, I noticed that the quality of OneNote’s voice recorder audios is similarly low.

I’m on a Pixel 6a with GrapheneOS.
