Since Ghost Radio normally records using the device microphone there are some things that are especially important:
- Ensure that the app sound is coming from the speaker, so don't use any type of headset (wired or wireless) while recording. The best results are achieved using an external speaker (wired or wireless) since these usually have better sound quality than the built-in ones.
- Also ensure that the volume level is high enough for the microphone to pickup the audio from the app and that nothing is obstructing the speakers of your device.
- Recording Limit, which can be set on the Settings screen, limits the maximum time the app records. When recording and the time limit is passed, the app will automatically stop the recording. The limitation on recording time, ensures that the app won't crash due to memory consumption or drain the battery of your device. If you encounter crash issues when recording, it can be an indication that you should try a lower recording limit.
- Certain devices have noise cancellation features which can interfere with recordings. If possible, try to turn it off in your phone settings (usually found somewhere in the Sound/Audio category).
- The Legacy Recording feature, which is activated from the Settings screen, allows you to record entirely without the microphone. You can enable this feature on the Settings screen. When Legacy Recording is enabled, the app will only record the sound that itself produces and the microphone won't be used at all. The app will save files in WAV format, which means that the recording files are larger than in the normal mode. To avoid instability the Recording Limits (Settings screen) will automatically be lowered.
- The Auto Recording feature which also is activated from the Settings screen, means that the app doesn't immediately start recording when you press the Recording button on the main screen. Instead of glowing red, the light below the recording button, glows yellow to indicate that the app is in auto recording mode. When the light is yellow, the app does not record, but is in standby to record: While in this mode the app will start recording automatically each time an entity is detected and then pause the recording when the signal is lost.
Each time this happens a new recording file will be saved and all recordings from an Auto Recording session is saved in a group folder. On the recordings screen you can browse such folders by clicking on them, much like browsing the file system on your device or a computer. When doing so, their contents are revealed, i.e. the individual recording files. You can use these files as normal, e.g. listen, delete or share them.
Some users have reported problems to start the Auto recording while an entity is already present. To avoid this problem, please start the recording immediately when the radio is started. As described above, the app will still not record until something interesting is detected and the Recording Limit applies only to each individual recording moment, so in theory you could be able to record for hours and still only get files with interesting content. The files produced when using Auto Recording is normally in M4A format or WAV format if you use Auto Recording together with the Legacy Recording feature (5).
- It is of course also possible to record using a third party app, or a digital recording device. This is especially a good alternative when using the app on older or low-end devices, since recording uses quite a lot of system resources.
- On Android devices, the app normally records files in AMR format, unless you have activated the Legacy Recording mode, which produces uncompressed WAV files.
- Recordings requires storage space on your device, so please ensure that you have enough free storage for recording files to be created.
- On Android 6+, ensure that the app has permission to use the microphone:
- Settings > App and select the Ghost Radio app.
- Tap App Permissions on the App Info screen.
- You will see a list of permissions the app requests, and whether those permissions are toggled on or off. Tap the toggle to customize the setting.
