Hello everyone!
   I've got a general processing question about csound. If I edit a soundfile 
through csound and write the result to disk, will csound add any extra 
latency or delay, besides that inherent to the opcodes used?
   Thanks and kind regards
              Julien

Hi,

Csound itself won't introduce any latency. But there will be latency from hardware buffering, and some opcodes (e.g. The pvs opcodes) will introduce some latency due to their particular processes.

Cheers,

Hi!
   Hardware buffers won't be a problem, since I will process already recording 
material via soundin.
   The thing I'm worrying about is the spat3d opcode? Do you by any chance 
know, if it has some latency due to its algorithm or way of processing data? I 
can find formulas to calculate distance related delays and such, but nothing 
about the overall output offset.
   Warm regards and thanks
           Julien

Hello Victor!
   I suppose, that is what I will have to do in the end. Perhaps I can subtract 
the original and the spat3d output, to see if it matches first. Best way 
without a waveform display in these short amounts of time. :-)
   Warmly yours
             Julien

Ypu can use the scale utility to find the place of maximum l.  Send the
impulse inverted to left and the processed to right

eg

scale -F 0.0 -o/dev/null trapped.wav

gives
Max val 29215.000 at index 6089122 (time 138.0753, chan 2) 1 times
Min val -31131.000 at index 7181622 (time 162.8486, chan 1) 1 times

Hello John!
   thanks for the tip, this is a utility, which might be of great hlep, not 
only in this instance.
   Warm regards
