Audio Signal Path
The audio signal path of a batch process is indicated by red, green, and blue arrows in the audio plug-in chain list.
-
A red arrow indicates that the signal is processed, then sent to the next plug-in.
-
A green arrow indicates that the signal is analyzed at this stage of the audio chain, but is not yet modified and therefore not sent to the next plug-in. When the audio stream comes to an end, it is restarted. Next time the signal reaches this plug-in, it is modified, and sent to the next plug-in. Some plug-ins need several analyses before passing to the next plug-in.
-
A blue arrow indicates that the signal has been fully processed at this stage and is written to disk.
-
A vertical separator line indicates that a meta-pass happens. This means that the files are read and processed again one after the other.
Some multipass plug-ins request more than one analysis pass, or send the signal further in the chain without ordering the audio stream to restart. This behavior depends on the plug-in settings and on the audio material and cannot be influenced.
