Gecko acquires a Pyramix DSD workstation

DSD (Direct Stream Digital) is to audio what RAW is to image: pure.

Some audio archives need particular attention. Unique albums, unpublished recordings or multitrack tapes are all rare and monetizable carriers, in a more than ever high-definition-oriented audio market.

In partnership with Numérisson, Gecko acquires a Pyramix MassCore Pro DSD workstation, combined with a Horus interface. Both conceived by Merging Technologies, they allow to digitize audio carriers at very high sampling frequencies.


With its unique 1-bit coding technology, it is possible to export multiple PCM audio files from this digital archiving audio format, of any resolution (16 or 24 bit) and sampling frequency (44.1 to 384 kHz), while retaining its sonic properties.

Digitization of analog audio carriers will now be possible up to DSD 256 fs format, also known as DSD Quad. Its sampling frequency, 256 times higher than a CD, allows audio to be captured with an exceptional definition (11.2 MHz), ideal in case of reediting or remastering, thus responding to long-term digital archival issues.

Digitization of audio cassettes Gecko

French biopic Barbara gets an Award for Best Sound

Fench movie “Barbara” just got a Cesar Award yesterday for Best Sound (alongside with the Cesar for Best actress) at the 2018 Cesars ceremony.

We are extremely proud to have played a part with the digitization of the live recordings that you can hear in the movie !

Maria by Callas, in theaters today

Today is the release of Maria By Callas in theaters in France and around the world (Italy, Great Britain, Japan, Germany, China…).


Written by and produced by movie director and Callas specialist Tom Volf, this 90-minute documentary is above everything the result of tremendous work. With an absolute true love for his subject, Volf spent no less than three years around the globe searching, collecting and acquiring never seen and never heard before archives of the most famous female opera singer in the world.


Between May 2016 and October 2017, we at Gecko have had the pleasure and the privilege to digitze more than a hundred reel tapes and about fourty cassette tapes for the making of this movie, as they were progressively found and brought back to France. Often kept and stored in the less ideal conditions, sometimes in a pretty poor shape, those tapes contained hours of interviews, rehearsals and live recordings. They recquired (sometimes heavy) physical restoration before playback to reach the best possible quality, and we are of course very proud of contributing to revive this incedible experience that’s listening to Maria Callas, singing.





We have been recently entrusted with a collection of 1,000 french chanson 78rpm shellac records from the 30’s. The songs contained in this one-of-a kind series are selected film songs typical of the historical period, often with a forward vocalist accompanied by a richly arranged score for small orchestra. Some lively and down-to-earth accordion songs can be heard, too. The collection features artists such as Maurice Chevalier and Charles Trénet, among lesser-known vocalists. The record labels are Columbia, Gramophone, Odeon, Parlophone, Pathé…

This digitization and restoration project has just been completed by our staff. Collection owner BNF-Partenariats is currently seeking for the best distribution partners.

The resulting files are not yet available online but you can hear some before/after audio restoration clips below :

Our 10-year long experience in 78rpm discs digitization and digital audio restoration for the Institut National de l’Audiovisuel (INA) and more recently for the Radio-Television Suisse (RTS) made it easy for us to quickly setup top-notch carriage, cleaning, databasing and digitization processes as well as a highly-tailored restoration process which included the production of two different restored audio files for each disc side. Complete metadata and photographs of the discs were also delivered.

Our real-world-optimized workflow makes for a highly cost-effective approach.

IASA 2016


We are glad to announce that our proposal for a paper presentation, “INA Selected Radio Broadcast Collections : A Long-Term Audio Restoration Project”, has been accepted into the September 2016 IASA Conference program. This will be a nice way for us to sum up our long restoration and digitization project for the french Institut National de l’Audiovisuel.

This year, the IASA conference will take place at the Library of Congress in Washington, D.C.


We will be happy to meet you there… Come and join us !
