Dear group, Here are my objects in my environment: > ls() [1] "Pos100415" "Pos100416" "posA" "pose15" "pose16" "pose16t" "position" "trade" "x" I need to pass the object "Pos100415" to a function. This element is a data.frame, obtained through a function: Pos(x)<-myfun(x) with x<-100415 in...

...d. However, I've had some limited success using two identical soundblaster live cards, card A (mic) and card B (output card which samples speakers). On each event (sampling capture position passed a marker in the buffer): - Fetch hardware sample-accurate sampling position of card A and B as PosA and PosB. - Copy 320 samples from buffer of card A at offset WantPosA into "mic input". - Calculate "negative offset" SampOfs = PosA-WantPosA. - Copy 320 samples from card B at offset PosB-SampOfs into "speaker input". - WantPosA += 320 - Wait for next event and...

To everyone on the list: do *NOT* attempt to do echo cancellation with signals sampled using different clocks. This will *NOT* work. Just a 0.1% difference between the two sampling rates (it's sometimes worse than that) means that the impulse response drifts by 8 samples every second. There's just no way to efficiently track this. Or at least no way that doesn't involve something 100x
