These are two songs, one is one of the best pieces of chieftains, the
other is piano lessons "heart ask pleasure first"
r1.wav = 2:43 (183 secs)
r2.wav = 1:36 (96 secs)
and inverting r1.wav and r2.eav is just the same...

no segfault...think that debug code intercepted the problem...

thank you for all the (good) work done with ecasound!
I am using it for a multitrack recorder for blind people...(I you want
