Hi Kevie,

As usually a well prepared show. I used for a while the app from Dolby https://www.dolby.com/en-gb/apps/dolby-on/ as it applies some "enhancements".

Just for the sake of an overall picture on mobile devices and PC also listen to episode 3673: https://hackerpublicradio.org/eps/hpr3673/index.html 

record on PC with SoloCast 
3496: How I record HPR Episodes http://hackerpublicradio.org/eps.php?id=3496
while the SoloCast became my favorite. As you can record paragraph by paragraph and take a break, for how long you want to, whenever you want to after a paragraph. 
When your done, it will: Combine the recorded segments ; Apply the noise reduction filter ; Truncate silence and export a file as FLAC.

Please give it try dear listener.

Cheers
