I am using avisynth and virtualdub to edit some videos together into a single file. Some of the files have louder volume than others so I used Virtualdub to adjust the volume until they were all pretty much the same. Now, when I want to open the .avs to edit all together, I get this:

"Avisynth open failure
the audio of the two clips have different samplerates, use
SSRC/()ResampleAudio()"

Where in the .avs code to I put this?
