[linux-audio-user] cross fade loopm which tool

Hi I recently discovered specimen, and what a nice piece of software!!! But I have a few problematic samples that just won't loop without clicking. I realize that since specimen merely points to samples and only offer basic loop point editing, I should look elsewhere for cross fade loops. But where? Is there a good linux based looping application that I can use for modifying the samples? And (pardon my ignorence) will loop points be saved together with the sample data itself in any format, perferrably one that's read by specimen, or do I have to write down the loop points and set them manually in specimen? -- peace, love & harmony Atte http://www.atte.dk
