Ratings and reviews

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.

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 $.

It is a very powerful audio recorder but trying to get the recording from the app to anywhere else is a nightmare. FTP and sharing to another app were useless. I searched the file directories in my phone (both hidden and not) and could not find it. Some people don't have this problem according to the forums but this was a big waste of time for me.

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
