Hi,

According to 'man ecasound' the -f argument gets applied to audio
objects (i.e. -i and -o arguments) that *follow* the -f
argument.

So as I understand it,

ecasound -D -z:nodb -f 16,2,44100 -i stdin -eli:1030 -b 4096 -ev -x -f s16_le,2,88200 -o alsahw,0,0

will accomplish what you want. In other words, ecasound will perform sample
rate conversion automatically just prior to output.

Is there a reason to think this *isn't* doing what you want?

Regards,

Joel
