Ratings and reviews

So far So good let me explain, first off Neutron's codec being used is just amazing, This mini Oscillator is really fun and to see it bounce around must of took some time. The codecs passing through work excellent i can hear myself clearly and even back noises are filtered. CBR and VBR is all their! can be set to any Kbps needed! The best part though is how quickly Recording can finish with 1 click its saved and then i can do it all over again 3 seconds later at the same Quality. Well worth $.

Clicking on Audio Hardware cause app to force close on Galaxy S24. App keeps stopping randomly when doing long recordings.

Very nice app. 🙂 Also use the Neutron Player, great app as well. 👍🏻 The only thing I'm really missing here, is the possibility to edit a recorded file. Very simple edits like cropping the selection needed. And amplification, normalizing and so on, after a recording is made. Plus being able to convert a recorded file into another format (mp3, flac, wav and ogg).

What's new

* New:
- loudness measurement: improved the RMS widget to show wider loudness scale from -60 to 3 dB
- show dB moving average value inside RMS widget for convenient reading of loudness
* Core updates and fixes inherited from Neutron Player release 2.24.0
