no, you cannot "slave" a real-time object to resample or resample-hq.

But you can do the reverse:

ecasound -t:3 -f:24,8,96000 -i alsa,default -erc:5,1
 -f:24,1,96000 -o resample-hq,44100,rec1.wav

... resample-hq is quite cpu-intensive (doesn't run in real-time on my
dual-450Mhz), so if you have problems, try with plain 'resample'.

This has been fixed in the latest snapshot:

Please test the resampling functionality for any bugs. I'm hoping
to release 2.4.0 soon.
