French trip-hop band Chinese Man has celebrated the 15th anniversary of its indie record label, Chinese Man Records (CMR), with a 360 degree video version of  ‘Hold Tight’, from its latest album Groove Sessions Vol 5, in binaural audio, in collaboration with RFILabo and SSL.

The Marseilles-based band blends hip-hop, funk, dub, reggae and jazz together, with a big emphasis on beats and samples. 

 RFILabo,  a division of French news and current affairs public radio station RFI, suggested the idea which quickly found favour.

“All RFILabo’s productions are in 3D sound,” explains Xavier Gibert, Responsable de l’Unité de RFI Labo/Innovation, “either in native binaural sound, or in synthetic binaural sound from the channel mode or the ambisonic mode. All the 360 videos that we produce are in dynamic binaural sound. That is to say that the sound space is coherent with the rotation of the spectator’s head.”

The track (full title: Hold Tight feat. ASM, Youthstar & Illaman) had the potential to be a great showcase for binaural audio.

RFILabo is a vocal champion of the format. It produces a music programme, SessionLab, in the format. The facility also records and mixes the electronic music concert series Séquence, broadcast on CultureBox (France Télévision) and RFI, in co-production with Milgram. It also makes documentary podcasts in binaural sound. 

“RFILabo’s work consists of producing binaural sound with minimal changes to conventional sound recording techniques,” explains Gibert. “The 3D sound should not change the creative process of the artists, a constraint we set ourselves at the beginning of RFILabo in 2012.”

The recording process is the same as for a normal recording, he adds. Microphones for the singers, lines for the machines, and returns for the musicians, and two System T S500 control surfaces and selection of Network I/O for recording and returns. 

“We keep in mind the same elements as for a stereophonic recording – rigor of the sound recording and comfort for the musicians. All the spatialisation work in the ambisonic domain is done in post production.” 

The RFILabo workflow sees the multitrack sound recording undertaken with the System T. Each track is processed as if for a stereo production. Recording is done in Pro-Tools. The spatialisation in the ambisonic domain is done downstream in connection with the 360 video, with the SSL Native plugin suite used to keep the sound colour of the take consistent throughout the process. 

“Our entire music recording studio is built around two System T configurations for sound recording and returns. The Dante architecture integrates SSL interfaces, KLANG headphones and DAD interfaces for all analogue peripherals. The advantages of the System T for this kind of production is the flexibility of the Network I/O stageboxes to easily manage the transition between ‘mic’ and ‘line’ levels, and to be able to make different ‘return mixes’ for the wedges of the DJs and the ear-monitors of the MCs.”

RFI has used SSL hardware since 2008, when the facility had its first console installed. System T has enabled it to keep the sound quality that it values so much while adding the flexibility and production capacity of a genuinely next generation audio production system. 

“We particularly liked the fact that this console, which was basically a broadcast type console, was able to evolve towards sound recording and music mixing,” says Gibert. “The other strong point is the ‘rehearse’ mode which allows us to switch to ‘mix’ mode very quickly after a recording, while keeping the same configuration.” 

“The integration of most of the functions in ‘touch’ mode is really well thought out and is largely completed with the use of knobs. We also appreciate the flexibility of the ‘Monitoring’ section and, of course, the fact that the quality of the dynamic and frequency processing remains faithful to SSL!”

And this is just the start.  Gilbert says he’s looking forward to future System T updates and enhancements to the binaural encoder.

“We have a project for a first live 360 in dynamic binaural sound! It will be a first!”
