When Zero Latency mode is active, look-ahead processing in Alloy's Dynamics, Limiter and Transient modules will be turned off allowing the plug-in to be used in situations where your host application does not have delay (latency) compensation. In these cases, adding latency to your audio is undesirable as it will make your tracks out of sync with each other, and cause phasing.
With Zero Latency mode inactive, Alloy will impose a small delay to account for look-ahead processing, allowing the modules to react to incoming audio material quicker. If your host has delay compensation, this short delay is not an issue as your host application will keep all of your audio perfectly aligned.
Due to this functional difference however, the sound and behavior of the Dynamics, Limiter and Transient modules will change slightly with Zero Latency mode On or Off.
The Zero Latency mode checkbox is located inside of Alloy’s ‘Options’ menu under the ‘General’ tab.
