How does the audio sound?

[SideShow Nate]

Hi there! New to this program! Just wanted to know how the audio sounds before I go further into this thing. I host a YouTube show where we do live interviews & performances from musicians around Michigan & need a service that delivers video & audio for our show. Zoom sucks for audio, so I'm hoping this service works! Can anyone fill me in? Is the audio quality good from a smartphone? Or is an audio interface necessary for our guest musicians to use it? And how would someone use this from a smartphone since I see there is no app on Google Play?
