[LAU] exporting ardour tracks with ecasound

Hello I used ardour to record a song for my friend. He is the one who is going to mix it (in windows) so I need to export those tracks to individual files. I could use ardour's export track, but it seems to me that i have to export each track one by one, and that would be time consuming. So I use ecasound instead. The command was ecasound -b 128 -r -c -f:32,8,48000 -a:1 -i jack -a:1 -f:32,8,48000 -o file.wav I do engine-launch, and connect each output from ardour manually. After that i do start in ecasound. The resulting file is an eight-channel wav file. The thing is, I'm kinda confused on how to proceed from here. I know I have to split it into individual mono files, but how, and with what. can I use sndfile- or sox, or perhaps ecasound itself? Second question, does recording this way adds extra latency of 128 frames to the resulting file? How long is that, in ms? Third question, I stumbled upon this http://lalists.stanford.edu/lau/2004/07/0523.html Now you might ask why the "-ea:400" (amplify by 400%) at the end of each chain. Now I regret having this feature in Ecasound more and more each day, but due to backwards compability issues, we just have to live with it. Basicly when Ecasound mixes together 'n' chains, it scales the amplitude to 1/n. This results in surprising results in the above case where each source chain has audible signal only one channel and the scaling doesn't make sense. Thus we scale it back up (no loss of information, just awkward. Do i need to use -ea:800 to scale the automatic scaling ecasound did? Thank you
