Merging Technologies is a Swiss manufacturer of professional audio hardware and software.

01History

Merging Technologies was founded in 1990 in Puidoux, Vaud, by EPFL electrical engineering graduate Claude Cellier, Jean-Marc Porchet, Dominique Brulhart and Markus Erne.

Early company goal was to quickly develop a Digital Audio Workstation building on Claude Cellier and Markus Erne previous extended audio experience and then pivot to a video editing system. However as it took 5 years to develop the 1st version of Pyramix a decision was made to postpone video editing to focus on Pyramix as v1 was far from the perfect audio tool it has now become.

In 2022, Merging Technologies was acquired by Sennheiser.

02Digital eXtreme Definition

DXD (Digital eXtreme Definition) is a digital audio format that originally was developed by Philips and Merging Technologies for editing high-resolution recordings recorded in DSD, the audio standard used on Super Audio CD (SACD).

Digital eXtreme Definition

Digital eXtreme Definition is a digital audio format that originally was developed by Philips and Merging Technologies for editing high-resolution recordings recorded in Direct Stream Digital (DSD), the audio standard used on Super Audio CD (SACD). As the 1-bit DSD format used on SACD is not suitable for editing, alternative formats such as DXD or DSD-Wide must be used during the mastering stage.

AES67

AES67 is a technical standard for audio over IP and audio over Ethernet interoperability. The standard was developed by the Audio Engineering Society and first published in September 2013.

Direct Stream Digital

Direct Stream Digital is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD). DSD uses delta-sigma modulation, a form of pulse-density modulation encoding, a technique to represent audio signals in digital format, a sequence of single-bit values at a sampling rate of 2.8224 MHz.
