Uden, Netherlands
What it is
Perfect Declipper is a Windows audio plugin for repairing recordings damaged by clipping. It estimates missing clipped information from what remains in an overly loud recording, and can restore clipped audio and some dynamics. The maker says results can in many cases be indistinguishable from an unclipped original, but also notes that lost data prevents perfect reconstruction and that multiple reconstructions may be equally good. Windows downloads include VST2, VST3, and Winamp/DSP plugins. Listed hosts include Adobe Audition, Audacity, Cubase, Cakewalk Sonar, and FL Studio; the plugin page also names applications such as PlayoutONE, Winamp, RadioBOSS, and AIMP. The Windows build is listed for Windows XP SP3, Vista, 7, 8, 10, and 11. A license costs €100, paid once; the optional Delossifier add-on is €130. Licenses are valid for life and include software updates, though new features may cost extra. The maker lists Perfect Declipper technology in several other audio and broadcast products.
