Yep, you can do this by using the ewf file format. First, create a text
file...

-- test.ewf --
source = test.wav
offset = 5.0
start-position = 2.0
length = 3.0
looping = true
--cut--

And then "ecasound -i test.ewf -o /dev/dsp". The first 5 secs will be
silent, then ecasound starts to read data from test.wav (offset inside
test.wav is 2 secs). After 8 secs (offset + length) of playback, we'll
loop back to start (2 sec from beginning of test.wav).

In currently released versions, ecasuond will crash if start-position
is greater thatn length. This is fixed in CVS.

Ok, I just added parsing of mp3 header info to the latest ecasound
CVS-version. Both mono/stereo and sampling rate are now handled
automatically.

That is nice to hear. :)
