Do I understand correctly that one sample from my ADCs will arrive at a
random moment within the lengh of one buffer in Pd?

Ah yes, WILMA! 

In my case I want to go for the best possible resolution without a
dedicated radio clock and with standard laptop hardware. Is banging
[time] at every microsecond still the best way maxing my cpu?

Thanks a lot!
