Unofficial VirtualDub Support Forums > Advanced Video Processing > Wav File Size Limit On Win 2000

vdub tells me the wav file may be corrupted at that point, giving sample numbers.

Any workarounds for this?

I'm assuming this is not a standards limit for wav files as several other players can read all the way to the end of each of these files.

No, this is not a w2k limit ...

... there is a standards limit for canonical wav files in the files RIFF header.

4bytes @offset4 define the file-length

these 4bytes are defined as signed-long, so there is a max-file-length of 2147483640byte.

you can find a more detailed description http://www.lightlink.com/tjweber/StripWav/Canon.html.

Not that I know! AFAIK VDub as well as AVISynth are only able to process canonical wav files.
