SSL X-ISM plug-In available free...
16.10.2007

Solid State Logic has released a VST/AU plug-in
X-ISM for Mac OS X and Windows, "which can interpret inter-sample peaks, allowing engineers to make informed judgements about the resultant sound quality of the mix." X-ISM uses processing to provide a combination of up-sampling and filtering that mimics the operation of an oversampling DAC's reconstruction process. The result is a meter that shows inter-sample errors and provides a useful tool that most DAW metering misses. Download the plug-in
from this page (requires registration), the PDF user manual can be viewed directly
here.
