Ahem, still a boy the last time I checked. ;)

Hmm, someone was using mpg123/lame for de/encoding individual module
samples and he reported similar problems. The decoding/encoding process
seems to add sample data. I'll check the ST-list archives for this.

Yep, I admit that ecasound documentation isn't as detailed as it could be.
My current aim is to keep documentation always up-to-date. To do this,
I have to keep it short.
Anyway, to understand -t and -tl, you need know how ecasound handles file
positions. When ecasound's engine is launched, all inputs and outputs
have already been opened. You might have modified their start positions
with -y:secs. Now ecasound stores the current starting position for all
inputs and outputs. Then it processes for -t:seconds. If looping is
enabled with -tl, it'll reposition all inputs/outputs with the saved
original start positions and continues processing.
