AttributeError: 'AudioFileClip' object has no attribute 'is_mask'

[DarkRedman]

Expected Behavior

Instantiating an AudioFileClip should works, as I realize my error after copying and pasting some vfx instead of afx for an AudioFileClip

Actual Behavior

I get this error AttributeError: 'AudioFileClip' object has no attribute 'is_mask'

After my realization I rather expect an error that says we can apply vfx on an AudioClip

Steps to Reproduce the Problem

from moviepy import AudioFileClip, afx, vfx

audio_clip = AudioFileClip(music_path).with_effects([afx.AudioNormalize(), afx.MultiplyVolume(0.8), vfx.FadeIn(fade_time), vfx.FadeOut(fade_time)])

• MoviePy Version: 2.1.1
• Platform Name: Linux
• Platform Version: 6.6.63-1-MANJARO

Well you try to use video effect on an audio only clip, you should use AudioFadeIn/Out instead. I think we an close.
