Powerful, but unintuitive UI and, unreliability keeps the app from potential greatness. Features and customization level: AMAZING. However, it's difficult to make sense of the interface. For example, many reviews complain about inability to export recordings. Adding a directory under the "sources" setting changes the target write dir. Also, preamp/EQ settings revert to a default after pressing REC. And, just now 90 minutes of recordings—yes, clock was rolling—have just simply disappeared.

You can add external user folder to Sources -> File System -> +, then create new source based on this entry and make it Active in Sources. With this you will get recordings saved in your user folder, for example/Recordings. DSP/EQ affect Playback and Recording sessions, so if you need EQ with Recording session then long press Record and activate EQ

Audio recorder works fine, even above expectations. Unfortunately, there are problems with access to recorded files - you could not copy them or transfer. Instructions given on other comments does not work (could be that are too complicated). That problems are the only reason why I have requested for refund.

You just need to create source entry via Android SAF permission and point it to any external user folder, such as /Recordings/ It is described with related screenshots: https://neutroncode.com/faq/58-empty-mlib On installation Neutron will ask for access permission for /Recordings by default, maybe you denied it?

I really enjoy this app and also purchased the Neutron Audio Player. However, on my S24 Ultra running Android 14, the app becomes extremely laggy and almost unusable when recording in WAV format. I tested it on other phones with Android 12, and it works flawlessly. I hope the development team addresses this issue in the next update.
