Trying to get AudioDub to work with .mp4 and .wav!!!!!

[Nagashi]

Ok. I have a .mp4 video file and a .wav audio file and I want AVISynth to combine them both into one .mp4 video file. Here is my script:

video=DirectShowSource("C:\Users\Nagashi\Desktop\Project X\01.mp4")
audio=("C:\Users\Nagashi\Desktop\Project X\01.wav")
AudioDub(audio,video)
FFT3DGPU(plane=4, sigma=0.1, sigma2=0.1, sigma3=2.0, sigma4=4.0,sharpen=1.2)
ConvertToYV12()

And it gives me this error:



So, I'm guessing I can't use audiodub with a .mp4..... Any info would be greatly appreciated!!!

audio=("C:\Users\Nagashi\Desktop\Project X\01.wav")

Should be:
audio=WavSource("C:\Users\Nagashi\Desktop\Project X\01.wav")
