	Hi! I have an orchestra to six channels (5.1 surround). I am using opcodes /space/ + /spsend/; For the filtering of audio signals: - It is better to filter the audio signal into a tool that is "reverb"; or - It is better to pass the audio signals already filtered before (inside the instrument in which they are space + spsend) to pass opcode "reverb"? thanks e -- View this message in context: http://csound.1045644.n5.nabble.com/signal-filtering-and-reverb-tp5730148.html Sent from the Csound - General mailing list archive at Nabble.com.

	If the filters and reverbs are "linear translation invariant" (LTI) systems, as they probably are, then it does not make any difference whether you filter first, then reverberate, or reverberate first, then filter. Look up LTI on Wikipedia if want to know more about what it means. Basically it means the gagets have linear responses and you don't play with their knobs while they are running.
