Altough I fear a new round of discussions about clock-syncing coming up.

So please, if you create homepage for the app, state the problem and the fact
that your (nice!) app is not a solution but only a patch to the problem...
Otherwise it might well be that people complain to you about their recordings
sounding less good then with a real multichannel device. And people
complaining here that with apps like yours, the market for multichannel
devices should be dry within weeks...

Have fun and keep on hacking,

Arnold
