Cambridge v13 debuted by CEDAR

Retouch 8 has been added as part of CEDAR's Cambridge v13

CEDAR Audio’s Cambridge audio restoration platform has been updated to v13, introducing a new impulse noise eliminator, Retouch 8 and improved performance.

The new INR is a real-time impulse noise deduction module that was developed as a more powerful alternative to CEDAR’s Declickle. The manufacturer describes that it is capable of digging deeper into the signal to remove the clicks and noise bursts that Declickle could not. While its primary use is in the forensic arena, it can also be used for badly degraded commercial audio, such as optical soundtracks with noisy clicks and bursts that are not recognised by other declickers.

Retouch 8 is the next version of CEDAR’s spectral editing suite and adds two new capabilities: Matching and Repair. Matching makes use of machine learning to identify unwanted sounds. The user marks one of the offending sounds and the software searches for all other instances within the recording. A threshold control allows users to bias its decision-making toward including more or fewer possibilities to find the desired level. Having identified all of the matches, they can be eliminated using the appropriate Retouch tool.

Repair, on the other hand, uses artificial intelligence to do its job. Users mark the sound and some of the surrounding signal and then use the single knob to suppress it or completely eliminate it. CEDAR says that unlike other spectral editing tools, only the significant signal within the region is identified and processed, leaving all low-level signals as well as the ambience unaffected. Repair also allows users to bring items in clips to the foreground by amplifying the event while leaving the rest of the signal unaffected.
