Merging Technologies

Nagra T Audio TC, from Nagra Kudelski Merging Technologies is the world’s foremost manufacturer of high-resolution digital audio recording systems. Our list of customers reads like a who’s who in the recording industry and recordings made with Merging Technologies’ systems regularly receive the recording industry’s prestigious Grammy® Award. So many in fact, that we have lost count.

The company was founded in 1990 in Chexbres, Switzerland by Claude Cellier; an electronics graduate of the Institute of Technology in Lausanne. Prior to this, Claude worked for the famous Swiss audio maker Nagra Kudelski for 10 years. Nagra is well known to music lovers for their audiophile products, but they are even better known in the professional audio industry, where their products are work horses, providing first class audio performance and doing so day in, day out. Legendary among these are the Nagra IV-S and Nagra T-Audio TC analogue tape recorders, where Claude played a pivotal role in their design and development.

Within a short time of its founding, Merging quickly established a reputation for their expertise in digital signal processing and associated hardware, and with their Pyramix Virtual Studio, was one of the first companies to produce a DSD recording system. The DXD format, (Digital eXtreme Definition) which works at 352.8kHz/24bit, was developed by Merging Technologies in collaboration with Philips, to overcome the challenges in editing and mastering DSD for SACD.

A First Class Pedigree

Grammy winning mastering engineer Bob Ludwig, Gateway Mastering Studios, USA  Merging Technologies has a formidable reputation in the professional recording and mastering world, where we have been at the forefront in the development of high-resolution digital audio recording systems for 25 years. The company has been a leader in providing workstation technology to support surround sound for more than 15 years and providing a practical mastering solution for surround on SACD with a complete authoring toolkit was another Merging achievement. The SACD legacy is many fine recordings in surround which can finally be enjoyed on the 8 channel MERGING+NADAC, by accessing the files from  our partners’ download sites.

Today leading recording and mastering engineers around the world put their faith in our technology to produce the vast majority of DSD and DXD recordings that are available on disc and online. To address the growing trend for immersive sound formats from Dolby, Auro and DTS, plus demands from venues and events for increasingly large speaker arrays, Merging has just introduced a 3D panning engine for use with Pyramix and Ovation software. The innovation continues… Among a prestigious list of worldwide recording and mastering engineers as well as world class facilities, concert halls, opera houses, symphony orchestras and philharmonics, the two maps of the US below show some of the concert venues and mastering houses that demand the highest quality and have installed Merging equipment.


Impulse response (from left to right) of an Analog, a 48kHz, a 96kHz, a 192kHz and a D.S.D. system on a -6bB Dirac Impulse (‘click’) of 3 µs duration.   DSD is regarded by many as the ultimate in digital fidelity and the most “analogue sounding” of all digital delivery formats. Merging Technologies has been developing solutions for DSD since the inception of the Super Audio CD in 1999, delivering ever-improving DSD recording and processing systems for the professional audio community.

The first DSD256 (11.2 MHz sampling) recordings were made in 2013 with Merging Technologies equipment and have been acclaimed by many top engineers and producers as another revolution in audio recording and reproduction. DSD256 works at 4 times the rate of the original DSD64 and provides a major improvement in sound quality, as well as a significant improvement in the noise characteristic. This is backed up by enthusiastic feedback we have received from our professional users. Despite its many advantages from the audio perspective, DSD is difficult to process. The solution was another Merging Technologies development.

DXD, Digital eXtreme Definition, was created by Merging Technologies to seamlessly move a DSD file into a PCM environment so that editing and processing can take place more easily.

Now an integral part of the modern DSD production chain, DXD has become a deservedly remarkable recording system in its own right. Working at 352.8kHz at 24bit resolution it provides a level of quality that far exceeds the currently accepted high-resolution audio formats of 96kHz/24bit resolution and 192kHz/24bit resolution. Merging Technologies is still the only company able to offer a really flexible and practical solution for recording and post producing true High Resolution Audio.
