Ces dernières années ont marqué une évolution très rapide du paysage spatial sonore.
Sous l'impulsion vraissemblable de la Réalité Virtuelle, le vieux concept de "son 3D" s'est vu rajeunir et s'épanouir avec le "son immersif", et on est passé d'une situation où le 5.1 et l'octophonie semblaient déjà osés à une explosion du codage ambisonique et des dômes, où même des éditeurs de logiciels plutôt frileux comme Avid et Steinberg se sont senti obligés de sauter quelques étapes ;-)

De mon côté, avec la série de plugins 64 bits pour Windows et MacOS depuis 2018,  il est devenu nécessaire de mettre à jour et de repenser l'ensemble des tutoriels que j'avais déjà consacrés aux Acousmodules et à leur environnement.
Car du côté des utilisateurs, les choses paraissent encore souvent compliquées, et les présentations faites par certains éditeurs de logiciels entretiennent parfois une confusion dans les notions et dans l'utilisation des outils.
Les hôtes qui supportent le multicanal jusqu'à 64 canaux ne sont toujours pas légion, et si Reaper, Bidule et Usine Hollyhock représentent à mon avis les meilleurs choix, il en est qui sont techniquement excellents mais dans lesquels la création multiphonique en haute résolution reste comparativement difficile (Ardour, Pyramix...).

Les ressources présentes sur cette page devraient aider à clarifier certains aspects de l'utilisation des Acousmodules et du travail multiphonique en général ?

Recent years have marked a very rapid evolution of the spatial landscape sound.
Under the realistic impulse of Virtual Reality, the old concept of "3D sound" was rejuvenated and blossomed with the "immersive sound", and we went from situation where 5.1 and octophony seemed already dared to an explosion of ambisonics technology and domes, where even rather cautious software editors like Avid and Steinberg felt obliged to skip a few steps ;-)

On my side, with the 64-bit series of plugins for Windows and MacOS since 2018, it has become necessary to update and rethink the whole tutorials I had already devoted to the Acousmodules and their environment.
Because on the user side, things still seem often complicated, and presentations by some software publishers sometimes maintain a confusion in concepts and in the use of tools.
Hosts that support up to 64 channels are still not legion, and if Reaper, Bidule and Usine Hollyhock represent in my opinion the best choices, there are some who are technically excellent but in which the high-resolution spaces creation remains quite difficult (Ardour, Pyramix...).

Resources on this page should help to clarify certain aspects of the use of Acousmodules and multiphonic work in general ?

Notes :
- most of the working hosts (Ardour 7.3, Bidule, Element, Max/Msp, Premiere, Reaper, Usine ...) accept plugins with a different or a higher number of channels that they are set for in their tracks or outputs, so don't worry about the numbers and choose the plugins that have at least the value you need
- host that are limited to 8 channels busses (Cakewalk, DaVinci Resolve free, Logic Pro, nTrack Studio, Protools Ultimate with a wraper like DDMF) are mentionned but there is not much interest to use the Acousmodules with them, and anyway they often accept only the precise number of channels and there will be very Acousmodules that have only 8
- Audio Editors (Acoustica, Audition, Resample, Soundforge, Twisted Waves, Wavosaur): even if it works technically the Acousmodules generally need to be controlled in realtime from gestures or automations for which this kind of software is not adapted
- Nuendo, Resolve Studio and Sequoia: the channels' mapping of the VST3 Acousmodules is not recognized in these hosts, but in Windows you can convert them as VST2 64 (just rename the .vst3 file inside the plugins folders as .dll!). The reason is that Steinberg has tied the VST3 multichannel specs to a series of named/predetermined physical speaker arrangements which tops out at 22.2. So to use free speakers arrangements with more channels like with the VST2 format hosts have to override or to ignore these specs. Some do, some don't. The consequence is that if they follow only Steinberg's way the multichannel IOs of these plugins are not recognized. Another problem, even with VST2, is that these hosts generally need the plugins to present exactlly a specific number of channels, so there are very few Acousmodules that can be used with them :-(
- some hosts (Cantabile, Mulab, Waveform ...) are technically able to handle multichannel plugins very well, but their implementation make alas this use nearly impracticable (too much complicated to connect every channels)
- MacOS VST3 support is possible but due to Apple security policy it is limited to Intel versions
- the VST2 32 bits plugins must work in 64 bit host which have internal bridging (and of course in 32 bits hosts)
- some hosts support MIDI inputs in VST3 FX, others don't or will later, must try ...
- special cases: Bitwig, Live and FL Studio: they don't have multichannel busses but there is workarounds that allow to use some multichannel plugins with limited features; Bespoke: crash when opening the plugins; Digital Performer: multichannel I/O are not recognized; Logic Pro: plugins that have exactly 8 inputs and outputs must logically work on a 7.1 bus but they may not pass AU validation; Twisted Waves: the plugins need to have exactly the same number of channels as the audio files, which has little chance to happen with the Acousmodules

 

  

V I D E O S

 (work in preogress ...)

In these short videos, I will try to give the essential clues to help you to know what you can do with these plugins and why you may need them... or not.
Please also read the global presentation documents and tutorials (yet mostly in french) and the PDF files that must accompany each plugin.
The informations that are given on the guide can also be useful, I hope.

Since in multichannel sound the loudspeakers arrangement matters, the ones that are used in these videos are : Atmos 7.1.4, NHK 22.2, 31 channels Dome (Montréal Satosphere's mapping), 36 channels 3D Grid, 48 channels 3D Grid (4D-Sound like), 45 channels Dome, 54 channels sphere, 3D Ring 59 and 63 channels (my "acousmonef"), 64 channels 3D Grid. The spatial peaks levels view that is present in all the videos has no other purpose than to make them more understandable.
Of course, all these examples can also be adapted or downscaled to other compatible spaces, but some of them risk to have less meaning...

Note about the binaural sound : the multichannel output in these videos is converted in realtime with the free GRM-Tools SpaceVR plugin.

only one version for everything, lighter on CPU during automations, DBAP mode, non limited to panning, stability
-
not constant powered DBAP mode, confusing and difficult to use with a high number of speakers with height, the global parameters are not automatable, groups of inputs cannot be stored/recalled, works only inside Reaper...

+
only one version for everything, simple to edit, constant power DBAP, zoomable interface, complex trajectories
-
individual inputs cannot be controlled or automated, agitation (random) only animation, possible gain rejections of the DBAP method, not free ;-)

+
easy to set even with high number of speakers with height, Layer based versions, original spatial mass effects, complex 8 / 16 inputs automations with only a few global controllers and animations (
AnimaSpat)
-
more complex to adjust than the other two, one must choose the appropriated version, limits of the DBAC method for periphonic speakers arrangements, CPU use during automation

Spatial format conversions

 

Alternatives to the Space Converters: for spherical layouts only, and if you don't need precise points > 5th or 7th order ambisonics with IEM's encoder/decoder (free); for 3D surround and spherical, if you can spend some money > Flux Spat Revolution (1600 € + iLock + powerfull computer) or IRCAM's Panoramix (120 €); for everything, if you don't mind eyes bleeding and nervous breakdowns > Reaper's ReaSurround; for everything too > GRM-Tools SpaceMaster (free and the easiest to use).

** subjective, depends on . The standalone applications obviously need a more complicated setup since they relay on an audio (and OSC) bridge between them and the DAW.
*** in static mode, that is without automations. Comparison has been made with a 64 x 64 conversion on a Windows 10 and a MacOS computer in Reaper, with the ReaSurround taken as a 100 % base. The value is the one given by Reaper which is coherent with what is reported in the Task Manager (Windows) and the Activity Monitor (Mac). For the standalone applications the value is only based on what the system reports.
