Pyramix DAW Drives
Varied RFI Workflows

Radio France Internationale (RFI) produces short wave to binaural streaming workflow in a multichannel /
VR production with Merging Technologies' Pyramix...
Xavier Gibert, RFI

R

FI is a news radio station
broadcasting in French and 13
other languages to all five continents. It
is broadcast on terrestrial channels, by
satellite, on the web and on connected
applications. Every week, this global
radio station has 41.3 million listeners
and its digital environments record
13.7 million visits per month as well
as 15.9 million Facebook and Twitter
subscribers.
Since 2015 the projects that require
it are broadcast in binaural sound
to be listened to on headsets on the
France Medias Monde websites and
social media.
Pyramix has been used for many
years, firstly for vinyl mastering and
digitisation. RFI has one of the largest
archives of African music. In 2012, RFI
Labo was created to introduce new
technology into the RFI production line
in order to make radiophonic writing
progress. RFI Labo has a Pyramix
Masscore and a Pro Tools connected
to a Horus for post-production. Since
then, several Pyramix Natives with an
interface adapted for directors and
editors are used for their multichannel
productions. This tool was selected
for its flexibility, the adaptability of its
interface and its bus mixer structures
that can use 22.2 for example, not to
forget its full monitoring section.
Multichannel projects are produced
in stereo for terrestrial broadcasting
and in binaural for the web. An
increasing number of programmes

include video to be more suitable
for broadcasting on social media.
Recently, VR 360° was added to the
RFI Labo works. For these productions,
the entire technical methodology for
sound capture, journalistic writing and
post-production had to be reviewed
and adapted. This work was directed
by Xavier Gibert (in charge of the RFI
Labo production unit). Gibert says: "In
2012 we created RFI Labo following
our 5.1 experiments and we were able
to go further for productions, firstly
in sound binaural only and starting in
2015 with video. Merging tools - first
and foremost Pyramix - were always
used in these projects. Currently there
is a team of three TCRs (Radio and
Video) in Abidjan with a journalist and
a production manager to cover the
FEMUA festival, which is an important
event in Africa and beyond"
The journalists also had to adapt and
change the programmes' narrative
sequences; compared to mono or
stereo recording; immersive sound
recording requires less description of
the location. Immersive sound is often
enough for the listener to understand
the space. As a result, the journalists
have to include pauses or transitions
in the rhythm of their reports. Gibert
says: "We managed to make our senior
management understand that when
all media was on digital platforms, we
needed to differentiate ourselves, but
how? Firstly through content, but also
through our subconscious relationship

with listening comfort. With binaural,
the location's emotion will pass
through the space and listeners can
project their own emotions."
Gibert has researched the recording
methodology and depending on the
content, the usual scheme is shown
in Fig. 1: "We will have a dozen tracks
recorded simultaneously. Depending
on the content and the location, we
use an IRT cross or a double MS with
spot HFs so why not native binaural
recording". In the studio, metadata is
retrieved in Pyramix and the elements
are de-rushed and edited. A "bed"
is created in 5.1 or 7.1 (basic direct
sound mix) and then elevation and
narration elements recorded in the
studio are added before the final mix.
The b<>com binauraliser is on the
outputs [Render Spk2Bin] from bcom
'Spatial Audio Toolbox' that allows
a multichannel audio 3D with virtual
speakers approach. "For the 360
VR we use the same method except

that we have three binaural output
buses, one bus with the bcom plugin
for our web platforms, another one
with the Noisemaker bus for YouTube
emulation and a final bus for the
Facebook plugin. The image is on a
temporary VCube. We will soon be
receiving a new VCube which will make
it possible to read 360 files without
reduction and to include the metadata
during the wrap."
Gibert says: "For the future we would
like to have portable solutions to
directly produce content on location
without having to use the studio
phases."

Technologies
Maurice
Engler adds: "We have always had a
constructive relationship with Xavier
from RFI because he has the agility
to understand new technology and
to include it in his production mode.
Without him, the production workflow
and the implementation of binaural
plugins wouldn't be as smooth."
