""" Returns a clip with audio volume multiplied by the

value `factor`. Can be applied to both audio and video clips.

This effect is loaded as a clip method when you use moviepy.editor,

|

so you can just write ``clip.volumex(2)``

---------
|
||
|
|
|
||
|
|
>>> newclip = volumex(clip, 2.0) # doubles audio volume
|
||
|
|
>>> newclip = clip.fx( volumex, 0.5) # half audio, use with fx
|
||
|
|
>>> newclip = clip.volumex(2) # only if you used "moviepy.editor"
