CEDAR Cambridge vs Diamond Cut Audio Restoration Tools 11.09

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.
