This is either 1) ecasound bug; it shouldn't change the relative volume
level of the independent ewf files, or 2) the difference you are hearing
is normal variation in loudness (peak-normalizing is not the same as equal
Possible things to try:
- load my_song.wav into an wave editor (ecawave, snd, audacity, ..)
and check whether there are distinct differences in the
- add an amplifier effect to each ewf-file chain and adjust
the loudness manually...
