Apple has fairly strong incentives to improve recording quality overall, including just better audio quality for the videos you shoot. Given the form factor of the iPhones, I'm frankly blown away by the sound quality you get from them. The SPL they can handle is absurd. Admittedly, your comment made me curious - I think I might have to annoy my neighbours with some bass playing this evening. In my experience, recording with my iPhone Xs, the bass frequencies of my synth are picked up extremely well. If the bass is indeed lacking, maybe we can recover some of it algorithmically. I'm not thinking about EQing, more like having a fantastic paper idea for some good academic work :-).
