About this app

Neutron Audio Recorder is breakthrough in a field of audio recording on a mobile device and PC! It is an advanced audio and voice recorder that is using famous audiophile-grade platform-independent 32/64-bit audio engine well-known to those who are enjoying music with Neutron Music Player.

* DSP

As a result of such symbiosis it is now possible to provide rich and market-unique DSP functionality available for your recording needs, briefly:

- Silence Detector helps to skip silence, record only valid sound and thus get smallest possible file even if recording lasts 24/7
- Up to 60 band Parametric Equalizer for correcting the frequency response of the audio source (microphone)
- Generic fully configurable DSP Filter for sound correction during the recording
- Automatic Gain Correction (AGC) allows to target the desired Gain and thus you can sense distant and quite sounds that become well recognizable in your recording
- High quality Resampling allows to reduce the size of voice recordings without quality degradation, so you can record lengthy lectures and memos in a tiny files

* MEDIA LIBRARY

Full-featured media library is now at your disposal for the recording needs. It allows to organize recordings flexibly and group them into the playlists.

* UI

User interface offers a precision Spectrum, RMS and Waveform analyzers, so recorded sound will be visualized in full.

* HI-RES AUDIO

Audio driver supports hi-res format, so if your device supports it Neutron has no limit to capture sound in high resolution.

* VERSATILE AUDIO FORMATS

You can choose to store recording in the lossless hi-res formats (WAV, FLAC) or in the lossy formats (OGG/Vorbis, MP3, SPEEX, WAV-ADPCM) to save storage space. You can store hours of voice recording using specially optimized for such task SPEEX format.

* STORAGE

You can store recordings in the Local storage or external SD or stream directly to the Network storage via SMB or SFTP protocols in real time, so if anything happens to your device during the recording process the recorded file will not be lost. Tags can be edited anytime after the recording.

Ratings and reviews

Total junk app. For some reason, it has stopped creating recording files. Extremely complicated interface and options keep changing on their own. When I installed this program, I configured voice recordings to go to the Recordings folder. At some point, it automatically changed the location of recorded files to some internal location which was accessible only via FTP. Now it has completely stopped creating any recordings. No support from developer.

Warning, you must create a new folder for recordings otherwise you cannot access your files outside of the app or transfer them. NOT impressed, also strange noise in recordings like an electronic interference sound which doesn't happen with the phones default app.

Yeah, the GUI is weird, but between reasonable permissions, better choices of formats, and simply better sound it's the app of choice.

What's new

* Targeted Google Play apk to Android 13 as per Google's requirement (note: if your source entry became inaccessible or empty - recreate new via SAF, see FAQ on website about it)
! Fixed:
- Filter DSP: Q giving insufficiently steep slope for Shelf filters (HS, LS)
- file access permission access requested again on start in some cases
