CEDAR Cambridge vs Vinyl Restoration Suite

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.

Vinyl Restoration Suite is a free audio restoration plugin and standalone application for Windows, macOS, and Linux. It detects and repairs clicks and pops using crossfade and spline interpolation, and reduces noise with real-time FFT processing that can capture a noise profile. Its AI denoiser is based on RNNoise and supports DirectML and NPU acceleration. A 10-band graphic equalizer covers 31 Hz to 16 kHz, while separate filters address subsonic rumble from 5–150 Hz and AC power line hum from 40–80 Hz. The app can record audio and split tracks automatically at silence. Real-time waveform and spectral views help monitor audio, and Difference Mode plays the noise and clicks being removed. Use it as a VST3 plugin in a DAW or independently as a standalone app. Pre-built binaries are listed for all three desktop systems; the macOS DMG is described as universal for Intel and ARM. It is available under the MIT license at free.
