Freeware: Voxengo Latency Delay

Latency Delay is an auxiliary AU and VST plugin which allows you to
compensate latency produced by any audio plug-ins, instruments and
processes which produce latency but do not try to report it to the
host. Latency
Delay introduces 10000 samples latency itself and delays
the audio signal by 10000 minus the specified amount of samples or
milliseconds.  Please note that host audio application should support
the latency compensation itself for this plug-in to function properly.

This audio plugin can be loaded into any audio host application that
conforms to the AudioUnit or VST plugin specification.

This plug-in is compatible with Windows (XP and later
versions, 32- and 64-bit) and Mac OS X (10.4.11 and later versions,
Intel and PowerPC) computers (2 GHz dual-core or faster processor with
at least 1 GB of system RAM recommended).  A separate binary
distribution file is available for each target computer platform for
each audio plugin specification.
