@aaronpk didn't realise you were smashing it on YT: congrats man!
I've actually been looking for a USB-c mic to record music on-the-go. Do you think cardioid-mode would be good enough for professional recording takes? You'd like to think CEO David Brown (played sax for Beck) would make sure, but wanted your opinion.
As recording artists, we're told to sing from 6in away from mics usually, so your observation on that is probably a suggestion it's good quality.
Finally, as you have an interest in Mevo livestreaming:
I recently raised my mic game on my weekly YT livestreams using Rode VideoMic Me lightning into iPhone (compare this to any of the earlier ones in playlist which just used Mevo Mic).
Reckon the Tula would be a similar option on iPad using the Mevo Mic app?
