... The
sample-in/sample-out may work at steady state, but if you use an FIR
filter, it still takes a number of samples and time to fill the filter
pipeline, as well as empty it...
Exactly. As I stated, you can't get away from the delay in the filter.
I was describing *additional* delay beyond that of the filter.
If the system is sampling at 48 kHz, a sample-by-sample architecture
will have 20.8 *micro*seconds delay before the subsequent filters, etc.,
see the signal.
If it is block based, and the block size is 1024 samples, then at the
same 48 kHz sample rate you'd have 22 *milli*seconds of delay before the
subsequent filters, etc., see the signal.
Sorry if I wasn't clear on that.
Enjoy!
