For remote interviews, ask the other party to record themselves on their own phone and send you the file, the audio should be so much better than Zoom, it’s a common tool reporters use. I would suggest stick with using Audacity and buy myself a H1 zoom, or if you have more cash, the H2 or H4 zoom recorder is really very sweet device for podcasts recorded in noisy environments like cafes. https://www.amazon.co.uk/dp/B07KXV2NWW/ref=cm_sw_r_tw_dp_x_boSfFb0FYZA7F A dedicated recording device is better than your phone mainly because it removes distraction and is more reliable if you use the device often and get familiar with remembering to charge the battery etc. Often you need 2 microphones, and this fills that role very well.
Anchor sounds nice, but it’s not really that hard to build your own RSS file, host it wherever you please at very low cost and take complete control of how your feed looks. It took me 2 days (of waiting time) to get a podcast registered on 3 different platforms, and about a week of XML hacking to get Facebook integration (It pulls/steals episode artwork directly from a facebook page, so simply.) Nothing stops you using apps like Anchor to get started though, so it’s a great way to start. They also do the SEO for you, which is the really hard stuff initially.
I’m not a podcaster, this was for a weekend-warrior project, which I hope to push up on github once I can strip out passwords, summon the courage, and to share the podcast itself, which is just hosted on a vanilla web host.
