I suspect Ardour is performing latency compensation 'the lazy way', by just adding an offset to the sample indices used to read a track that has processing latency, and make the transport compensate for this, rather than by inserting _real_ delays in all other processing paths. This works, IFF the following assumptions are valid: - all signals sources are tracks being played back, - the signal from a track will not follow parallel paths, - or if it does, all of them will have the same latency. It's simple and will work in many, but not all cases. The more general solution, considering what can happen if you have parallel processing paths (pre and post fader sends, 'real' groups, tracks split off to a separate strip for some reason, etc.) can be very complex - maybe too complex to allow for a reliable automatic compensation. In that case I'd prefer _no_ compensation at all to a partial or wrong one - it makes a finding manual solution easier. -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia Lascia la spina, cogli la rosa. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
