audio.fxΒΆ

The module moviepy.audio.fx regroups functions meant to be used with audio.fx(). Note that some of these functions such as volumex (which multiplies the volume) can be applied directly to a video clip, at which case they will affect the audio clip attached to this video clip. Read the docs of the different functions to know when this is the case.

Because this module will be larger in the future, it allows two kinds of import. You can either import a single function like this:

from moviepy.audio.fx.volumex import volumex
newaudio = audioclip.fx( vfx.volumex, 0.5)

Or import everything:

import moviepy.audio.fx.all as afx
newaudio = (audioclip.afx( vfx.volumex, 0.5)
                     .afx( vfx.audio_fadein, 1.0)
                     .afx( vfx.audio_fadeout, 1.0))

When you type

from moviepy.editor import *

the module audio.fx is loaded as afx and you can use afx.volumex, etc.

audio_fadein Return an audio (or video) clip that is first mute, then the sound arrives progressively over duration seconds.
audio_fadeout Return a sound clip where the sound fades out progressively over duration seconds at the end of the clip.
audio_loop Loops over an audio clip.
volumex Returns a clip with audio volume multiplied by the value factor.
