What it is

Perfect Declipper is a Windows audio-repair plugin for recordings damaged by excessive loudness and clipping. It calculates missing clipped information from the data that remains, and can restore clipped audio and some dynamics. Thimeo says results can in many cases be indistinguishable from an unclipped original, while also explaining that lost data makes perfect reconstruction impossible and that several reconstructions may be equally good. Windows downloads include VST2, VST3, and Winamp/DSP plugins. Listed hosts and applications include Adobe Audition, Audacity, Cubase, Cakewalk Sonar, FL Studio, PlayoutONE, Winamp, RadioBOSS, and AIMP. The Windows build is listed for Windows XP SP3, Vista, 7, 8, 10, and 11. A Perfect Declipper plan costs €100 as a one-time purchase, with an optional Delossifier add-on for €130. Licenses last for life and include updates, though new features may cost extra.
