Is there such a device where I can plug in 1/4" jacks and XLR jacks and the output is USB?

Right now I'm stuck in a problem in that I'm not getting a good sound by simply plugging in 1/4" jacks through 8mm adapters to my desktop computer. I was wondering if there was such an interface or something where I can plug in multiple 1/4" jacks and (potentially) XLR jacks and the output is USB so I can hook it directly up to my computer? Thank you, and sorry if it's the slightest bit confusing!
