Sample Grabber is a standard Digital Audio Workstation (DAW) plug-in for Flux's Pure Analysis System(PAS) software, available in all common formats (VST, AU, RTAS and TDM). (Please note that Sample Grabber is not a standalone program, but only a plug-in. In earlier versions of PAS, it was included in PAS itself.) Sample Grabber acquires signal samples for PAS to analyze from media stream(s) as they pass through the Windows filter graph.
