sounds like recorded in toilet

when i record from analogue source the recording sounds like i recorded it in the toilet or a tunnel. original recording ok and signal not overloading in put.
i’m using windows 8 but had the same problem on windows vista. what’s wrong or is it me???

Windows assumes you’re trying to make a business conference call, not a high quality recording.
