# Audio Editor

The audio editor, as its name suggests, is used to edit Audio functions.
It offers basic controls and shows information about the attached audio file.

## Controls

| Start/stop the audio file playback. If the file doesn't exist, this button will have no effect
Audio name | Change the name of the Audio function. By default this is set with the file name, until it is manually changed.
File name | Displays the absolute path of the current file attached to this Audio function. The source file can be changed by clicking on the "..." button on the right side.
Duration | Displays the audio file duration in the typical QLC+ way. For example: 04m14s.22.
Channels | Displays the number of channels detected from the attached audio file. 2 means stereo and 1 means mono.
Sample Rate | Displays the sample frequency of the attached audio file, in Hertz. For example: 44100Hz, 48000Hz, etc
Bitrate | Displays the bitrate of the attached audio file, in Kb/s. Audio files can have a constant bitrate (CBR) or a variable bitrate (VBR). In the latter case, an average bitrate is displayed.
Loop | Loop audio playback until explicitly stopped.
| Show/Hide the Speed Dial widget, used to facilitate the audio fade in/out parameters tuning
Fade In | Text box to enter a fade in time for the audio playback. Times can be entered in a QLC+ way (e.g. 3s.55) or in seconds (e.g. entering '2' and pressing Enter will turn into 02s.00)
Fade Out | Text box to enter a fade out time for the audio playback. Times can be entered like in the Fade In box
Audio Device | Select a specific audio output device to be used to play the attached audio file. This list is the same you can find in the Audio Input/Output panel
