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.


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

- up to 60 band Parametric Equalizer for correcting the frequency response of your recording source (microphone);

- generic fully configurable DSP filter that can be used for sound correction while recording;

- Automatic Gain Correction (AGC) effect that 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 size of your voice recordings without quality degradation of remaining frequencies, so you can record lectures, memos in a tiny files that is handy functionality for capturing long conversations.


Media library common to music player is now at your disposal for recording needs. It allows to organize recordings flexibly. You can also create own playlists composed of recordings, so grouping is easily achievable.

* UI

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


Audio driver supports hi-res input devices, so if your device supports it Neutron has no limit to capture sound with high resolution, for example 24-bit, up to 768 kHz.


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.


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.
