## Silence in media files
|
||||
|
||||
Before importing media, it is good practice to check for any silent sections in the media files. While LibreTime compensates for leading and trailing silence with the use of automatic cue-in and cue-out points****, it may be preferable to trim these files to the intended length before upload. This is because media in the LibreTime library could potentially be re-used in many different systems. **Audacity** is a cross-platform editor suitable for the task of trimming audio files, available from [http://audacity.sourceforge.net/](http://audacity.sourceforge.net "http://sourceforge.net/projects/dr14tmeter/")

This is because media in the LibreTime library could potentially be re-used in many different systems.

|
||||
|
||||
Very quiet introductions or over-long fades can also lead to apparent gaps in your broadcast playout. Some audio CDs feature a 'hidden track' at the end, which in fact uses a long period of silence within the final track, rather than an actual separate track on the disc. This means that CD encoding programs will often encode both the hidden material and the silence in the media file. For example, the track "Debra" from the CD *Midnite Vultures* by Beck includes hidden material preceded by seven minutes of silence, as shown in the screen shot from Audacity below.
|
||||
Quiet introductions or extended fades can also lead to apparent gaps in your broadcast playout. This is more common when playing back audio from ripped CDs or dubbed from tape or vinyl; this issue is not as common with digitally-purchased music. For best results, long periods of silence should be removed from files before uploading to Libretime.

## Restarting services
|
||||
|
||||
LibreTime is effectively a web site running on a LAPP stack, so individual components of the system can be started, stopped, restarted or checked in the server console using the **systemctl** command:
|
||||
|
||||
sudo systemctl start|stop|restart|status libretime-liquidsoap
|
||||
sudo systemctl start|stop|restart|status libretime-playout
|
||||
sudo systemctl start|stop|restart|status libretime-celery
|
||||
sudo systemctl start|stop|restart|status libretime-analyzer
|
||||
sudo systemctl start|stop|restart|status apache2
|
||||
sudo systemctl start|stop|restart|status rabbitmq-server
|
||||
```
|
||||
sudo systemctl start|stop|restart|status libretime-liquidsoap
|
||||
sudo systemctl start|stop|restart|status libretime-playout
|
||||
sudo systemctl start|stop|restart|status libretime-celery
|
||||
sudo systemctl start|stop|restart|status libretime-analyzer
|
||||
sudo systemctl start|stop|restart|status apache2
|
||||
sudo systemctl start|stop|restart|status rabbitmq-server
|
||||
```
|
||||
|
||||
For example, to restart the Airtime playout engine, you could enter the command:
|
||||
|
||||
sudo systemctl restart libretime-playout
|
||||
```
|
||||
sudo systemctl restart libretime-playout

```
