The ewf-format can handle offsets when in output mode. So instread of
writing to xxx.wav, write to xxx.ewf. Something like:

ecasound -c -a:mon -i song1.wav -o /dev/dsp \
            -a:rec -i /dev/dsp -o vocals.ewf -c

iamode> setpos 20
iamode> start

The resulting vaocals.ewf looks like:

--cut--
source = vocals.wav
offset = 20.000000
--cut--
