Merging granted patent for CEDAR’s closely-guarded ‘Retouch’ tech

Sophisticated audio repair technology will be available to users of the Pyramix DAW

CEDAR Audio (UK) and Merging Technologies (Switzerland) have entered into a non-exclusive license agreement that enables Merging Technologies to use “IPR” (intellectual property rights) contained within CEDAR Audio’s US Patent No. 7,978,862 ‘Method and Apparatus For Audio Signal Processing’, AKA ‘The Retouch patent’.

The patent refers to a method of displaying and editing audio content in a spectrogram, and then provide audio engineers with a means to find problems such as noise and other artefacts in recordings and remove them without affecting the wanted audio.

It is not the first time CEDAR has forged such a deal with third party developers for its highly desirable and sophisticated tech: an agreement with the (then) RX 2 Spectral Repair package maker iZotope was announced in 2012, for instance. (RX4 is the latest iteration of iZotope’s popular software.)

But CEDAR also takes enforcement of its copyright very seriously and has pursue infringements of the patent with ferocity: in May of last year, the Cambridgeshire company announced that it had concluded an agreement with Diamond Cut Productions Inc in the USA in respect of the Retouch patent. Having acknowledged the validity of CEDAR’s suit, Diamond Cut Productions was forced to recall its DC8 and DCForensic8 products and discontinue the Direct Spectral Editing features of the software.

“Like CEDAR Audio, Merging Technologies has a proud legacy of innovation and technology. We have been working with them since the mid-1990s when we began developing the first CEDAR for Pyramix processes,” said Gordon Reid, MD of CEDAR Audio Ltd, “and this agreement paves the way toward some exciting future collaborations between the companies.”

“We are delighted to renew our close working relationship with CEDAR,” said Claude Cellier, president of Merging Technologies. “Our customers expect to be able to use the leading audio restoration tools, and a new suite of 64-bit CEDAR for Pyramix will take advantage of the increased processing power and the latest developments from CEDAR.”
