In their own words
CEDAR Cambridge
CEDAR Cambridge is a 64-bit platform for speech enhancement and audio restoration on macOS and Windows. Its modular processing system can be automated and is described for audio forensics and security, archives and libraries, broadcast, and mastering. Voice extraction options include DNS, DNS Two, FNR, and VoicEX; other tools address noise, impulse sounds, and speech intelligibility. Retouch provides spectral editing, while dynamics, loudness control, and equalisation modules cover operations such as compression, limiting, and normalisation. Depending on hardware, processing can reach up to 100 times faster than real time. Cambridge can integrate with media asset management systems and add track reports and metadata to databases. Its Report Generator records processing details and produces PDF, HTML, or XML reports. Silent 1 is intended for individual users, while Series V is aimed at batch processing in archives, libraries, and forensic laboratories. The listed starting price is £349, with a 14-day trial; prospective hardware or systems buyers are directed to contact CEDAR Audio for pricing information.
Perfect Declipper
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.
