Q: On each track change the sound becomes overloaded (too loud) and then becomes normal, is it a bug?

No, it is not a bug. Most probably you misused Preamp gain functionality. You can fix it as following:
1) Make sure that in Controls screen you have Preamp slider in the middle position (0 dB).
2) Go to Neutron UI -> Settings -> Automatic Gain Protection -> check if RESET GAIN value is 0 dB, if not, move slider back and forth to reset to 0 dB.


Q: How to create my own playlist and add tracks to it?

Swipe to the Playlist screen (right most) -> go to top-level list by pressing [ enter to Playlists section and press [+] button -> you will notice newly created playlist entry. Then from other lists of tracks simply long press on song or group (album, artist, ...) and press [+ PLAYLIST] button -> in the list find playlist to which you are going to add entries, select it and confirm.


Q: Where is file of newly created playlist stored?

User-created playlist files are stored in the following location:
- Android OS: /sdcard/Android/data/com.neutroncode.mp/playlists, or /sdcard/NeutronMP/playlists
- BlackBerry OS: /shared/music/playlists


Q: After uninstallation and then reinstallation I have all my settings lost, is it possible to avoid that?

A: To avoid loosing your settings follow these steps:

- Android OS: close Neutron process, create folder NeutronMP in /sdcard to get /sdcard/NeutronMP, copy all files from /sdcard/Android/data/com.neutroncode.mp to /sdcard/NeutronMP, start Neutron, Neutron will use /sdcard/NeutronMP.

- BlackBerry OS: close Neutron process, create folder NeutronMP in /misc to get /misc/NeutronMP, start Neutron, Neutron will populate /misc/NeutronMP with files and use it for database storage.

Even if you completely uninstall Neutron that custom folder will remain and after re-installation you will have all settings preserved. On start Neutron will try to find that folder and load setttings from it, if failed then will use standard location.


Q: How to avoid playing ringtones and other audio files with non-music content?

A:You can do it in 2 ways:
1) Go to Playlist screen, scroll to Folders group, enter to it and find those folders which are not related to music, long-press on such folders and in opened window press IGNORE button. After this operation unneeded audio files will be removed from the database. Repeat the same operation for all non-music folders.
2) Re-create Source entry. Go to Playlist screen, scroll to Sources group, and enter to it then long-press on Source #N entry, in opened window press DELETE button. Return to Sources, enter to it and press NEW button in the bottom of the screen, in opened window scroll to music folders and select them with pin-button. Select only top-level folders (for example: if you have /sdcard/music folder, select it and not folders below this folder), multiple selection is supported. After selection is done press DONE button and Neutron will rescan selected music folders.


Q: Is there support for streaming audio?

A: Yes, there is. Navigate with Internet browser to the link you would like to stream, press on it, Android OS will offer the list of apps to open that link, choose Neutron from that list, Neutron will start and on its Display will be saying CONNECTING..., if format is supported it will start playing the stream. All streaming URLs opened like that will be saved in Streaming group in Playlist screen (below Queue group). Also it is saved in XML file: /sdcard/Android/data/com.neutroncode.mp/streaming.xml. It is possbile to edit this XML file manually and add/fill the list of URLs there.


Q: I can see basic controls on Playing Now screen but how do I access music selection?

A: Neutron is not traditional Android application. It has screens on the right and left sides from the Playing Now screen. To switch between screens press on Display area or anchors on screen borders. Swiping the screen also works.


Q: I do not see album art, does Neutron support it?

A: Yes. Neutron is not using system media database and thus will not lookup album art from it. Neutron builds own media database and searches for an album art in: folders where music files are located, or tags of music files. To have album art visible make sure that either one of these two conditions is met.


Q: Why do I get buttons inactive on Control screen if I do not touch display for a while?

A: It is special feature which automatically locks controls on Main screen with cover layer after 5 minutes of input inactivity (e.g. you do not touch screen for about 5 minutes). This is optional feature: Neutron ->Settings -> User Interface -> KEYLOCK.


Q: If I set Preamp gain above slider's middle position sound becomes distorted.

A: Preamp gain control is digital amplification mechanism. To adjust analogue gain of your device (loudness of speakers) you shall use device up/down volume buttons, or Neutron’s Master HW gain. Digital gain in normal circumstances shall not be increased above middle position of slider (>0 dB). Normal circumstances mean when audio is normalized (usually all commercial music is normalized). Using digital gain above slider's middle position (>0 dB) makes sense only if your audio is not normalized and is quieter than usual, for example if you are listening to custom recording. Amplifying normalized audio signal by using digital gain will lead to its guaranteed distortion. Use digital Preamp to decrease audio gain only if you increase gain of some frequencies by equalizer. Use it with care and when you know what are you doing! Otherwise simply use standard hardware volume controls and do not care about it.


Q: What does Surround mode mean?

A: Surround mode is using Ambiophonic R.A.C.E. algorithm to make stereo music spatial (3D like). It must be used with external speakers only because Ambiophonic R.A.C.E. technique supposes that audio frequencies of music composition will be mixed in the air before arriving to listener. The way such mixing is done causes effect of the surround sound.


Q: What does Crossfeeding feature do?

A: Crossfeeding is the special technique which mixes some frequencies of Left and Right channels of stereo music together. Crossfeeding must be used with headphones only and its goal is to simulate stereo perception of external speakers. Explanation: All music is composed with condition that it will be listened through external speakers thus composer takes into account that some frequencies of Left and Right channels will be mixed in the air before arriving to the listener. If listener is using headphones then no such mixing in the air happens and thus desired perception of the music composition is not achieved. Crossfeeding technique simulates such mixing and thus listener is able to feel music as if it is heard from the external speakers, e.g. in the same way as music composer planned it to be heard. Neutron provides several presets with different degree of mixing. Choose whatever preset you like or adjust to your own taste.


Q: Crossfeeding button is replaced when Surround mode becomes active?

A: Yes. Crossfeeding and Surround modes are mutually exclusive by operation, Surround widens stereo while Crossfeeding is narrowing it.


Q: Why do I need to know about Resampling?

A: Generally speaking, you don't. Until the moment when you get music files which have frequency other than 44.1kHz. Android OS is hard-coded to 44.1kHz frequency, e.g. if you have music files with the same frequency then no resampling happens. But if you get music with 48kHz frequency, or Studio quality music with 96kHz frequency then the real-time resampling will take place. Neutron provides 3 resampling methods which can be chosen depending on performance of your device.


Q: Can I change or stop music in Landscape mode?

A: Yes. Tap on bottom side of the screen and the sliding panel with playback controls will come out. Note, when NIGHT mode is active you won't be able to invoke this panel.


Q: I see WAKE button but how to setup wake-up time?

A: Simply long press WAKE button. Dialog window will appear with necessary controls. It is also accessible through Settings screen.


Q: Is it possible to delete Source entry?

A: Yes. Go to Playlist screen, press on Sources group and you will see all existing Source entries. Long press the entry you wish to delete, in opened window press the DELETE button.


Q: Can I register more directories which have music files?

A: Yes. Long press the Source #N entry and in opened window press the EDIT button to invoke directory selection mode.


Q: I created Source to some directory with music after Neutron's installation. Can I create more Sources to link some other directories with music?

A: Yes. Go to Playlist screen, scroll to Sources group, enter to it. In the bottom press the NEW button to invoke directory selection mode.


Q: I copied new music to the directory referenced by one of the Source entries but music does not appear in Neutron automatically.

A: It is intended behavior. Neutron does not scan anything on your device by itself automatically and it does not do anything in background with goal to save the battery lifetime and CPU power of your device. If you modified contents of the music directory, simply go to the Database View screen (Playlists, Artists, Albums,...), scroll the list to the Sources group, inside Sources, on each source entry switch off/on the [Refresh] button on the Source #N entry and wait until Neutron completes scanning ([REFRESH DB] message in Display area will be blinking during scanning). [Refresh] will only trigger quick scanning of missing/added music and album art files, for complete database rescanning you need to use [RESCAN] from the properties of the source entry.


Q: I modified tags of some music files but do not see the changes in Neutron.

A: You need to invoke properties screen on source entry by long press and use the [RESCAN] button to activate complete rescanning including tags.


Q: I can see CLOCK button on top of the screen. What does it do?

A: To activate CLOCK mode you have to long press the button. Neutron will switch off its playback functionality and start looking as digital clock.


Q: Does Neutron download album art from the Internet?

A: No. Neutron looks for the album art in the directory with music files or extracts it from music file tags. There are many Android applications (many of them free) which specialize on album art downloading. Neutron is designed for high quality playback.


Q: How to exit from the Neutron process so that it does not stay in memory?

A: Make sure Settings -> Service option is switched off. After exit from the UI, Neutron will run in background for 5 minutes and will stop self automatically. If WAKE time is active service will not exit. If music playback is active service will not exit but will do so after 5 minutes timeout when playback is stopped.


Q: Neutron takes more megabytes of the storage then other Android applications do. Why it is so?

A: In order to bring to you non-standard and unique application Neutron is developed fully in native code. It does not depend on standard Android UI and SDK version. It will look and work the same on any OS version and device (excluding device hardware capabilities). Such independence has a drawback – the increased binary size of application. Moreover to provide the best sound quality Neutron has own professional audio rendering core which also increases size of the binary. Neutron supports many additional audio formats and decoders which take space also! Nevertheless Neutron is movable to the external SD Card that solves problem with devices which have small internal memory.


Q: I found bug how can I report it?

A: It is absolutely fantastic if you decide to report the discovered bug! Please make new thread in Neutron Forum in Support section, so all users would add their comments and trace bug status.
