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 ?

 

videos - tutorials - hosts compatibility - gesture controllers - other free multichannel tools - comparison charts

 

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.

notes :
- in order to use the VST3 acousmodules as VST2 64 you can rename the .VST3 file inside the plugins folders as .dll, it may work ...
- Ardour (Windows) doesn't recognize the VST3 acousmodules as multichannel, so the previous trick must be used
- for the VST2 32 bits plugins the host must support bridging or it must be a 32 bits version
- host that are limited to 7.1 (8 channels busses) are mentionned but there is no real interest to use the acousmodules with them :-(
- even if it works technically, non realtime Audio Editors like
Acoustica, Audition, Resample have no real benefit from this kind of plugins
- some hosts support MIDI inputs in VST3 FX (*), others don't or will later ?
- Steinberg's softwares are using some very advanced and clever ways to deal with multichannel VST3 that prevents them to work correctly with more than 24 channels !
- Protools Pro must be able to use them with the wraper feature of DDMF or Element (not tested)
- Logic Pro X : due to its bus constrains it cannot use the acousmodules or they don't pass the AU validation process
- on MacOS, depending on how the hosts adress the graphic resources, the plugins' UI animations can be nearly as smooth as on Windows or more or less jerky. It can also depend on the graphic card and the OS version.
- not tested : Digital Performer, Live Professor Mac, MuLab, nTrack Studio, Premiere Pro

to resume

+
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, layouts cannot be imported/exported, limits of the DBAC method for periphonic speakers arrangements, CPU use during automation

* possibility to render a single point and to choose how each point extends to its neighbours

*** 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.
