Neutron Audio Recorder application is breakthrough in a field of audio recording on mobile devices and PC! It is an advanced audio and voice recorder that is using famous audiophile-grade platform-independent 32/64-bit Neutron HiFi™ Audio Engine well known to the Neutron Music Player users. All major platforms are supported - Android, iOS, Windows 10 (UWP).

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 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 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, for example 24-bit, up to 768 kHz.

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.

AGC: SENSE DISTANT AND QUITE SOUNDS

Neutron Recorder offers a unique functionality to record distant and quite sounds with the help of its Automatic Gain Correction DSP effect which is analyzing sound in real time and applies necessary correction to increase the dynamic range of the recording. With this feature you can speak in one room and can still be recorded!

FILTER: REMOVE UNWANTED NOISE FROM THE RECORDING

Neutron Recorder allows to remove the unwanted noise during the recording with its fully configurable Filter DSP effect. Filtering out the noise, especially the high-frequency one, improves the compression of the destination file if compressing format is selected for the recording. Cleaner sound will not require any post-processing, so you save time in real time!

EQUALIZER: COMPENSATE DEFICIENCIES OF THE SOURCE

Neutron Recorder makes it possible to compensate the deficiencies in the frequency response of the recording source during the recording process. Such approach helps to avoid time waste doing the post processing and makes recording ready for use once it is completed!
