What is this sound?

Anyone know what this sound is? It's only on channel 1 lsb. All the time, if skips running. I've recorded it but cant upload it here so I uploaded it to a hosting site called jumpshare.

I heard no sound on the share. I do believe I know what you speak of though. Sounds at first reminiscent of the old dial up internet to a degree.
