Description
PROCEDE ET DISPOSITIF DE CRÉATION D'AMBIANCE
MUSICALE OU SONORE
La présente invention a pour objet un procédé et un dispositif de création d'ambiance musicale ou sonore.ATMOSPHERE CREATION METHOD AND DEVICE
MUSICAL OR SOUND
The present invention relates to a method and a device for creating a musical or sound environment.
Ils concernent l'industrie des appareils de reproduction et de diffusion sonore ou de composition musicale destinés aussi bien à une utilisation personnelle que professionnelle: salles de concerts, discotheque, cinémas, etc. They concern the industry of sound reproduction and musical composition apparatus intended for both personal and professional use: concert halls, discotheque, cinemas, etc.
Les techniques actuelles de reproduction ou de création sonores sont entièrement basees sur la monophonie ou la stéréophonie. Même le système connu sous le nom de quadriphonie utilise en fait une source stéréophonique modifiée par des artifices relativement simples. Ces procédés ne permettent qu'une reproduction éloignée de la réalité et un relief sonore très limité, quelles que soient les raffinements technologiques utilisés par ailleurs. La musique, ainsi que toute source sonore produite dans ces conditions est complètement compressee, superposée, confondue sur elle-même. Elle est statique, elle ne vit pas. Current techniques of sound reproduction or creation are entirely based on monophony or stereophony. Even the system known as quadraphone actually uses a stereo source modified by relatively simple devices. These processes allow only a distant reproduction of reality and a very limited sound relief, whatever the technological refinements used elsewhere. The music, as well as any sound source produced under these conditions is completely compressed, superimposed, confused on itself. It is static, it does not live.
Les instruments récents de composition musicale permettent de faire appel à de multiples sources, instruments réels, sonorites de synthèse, enregistrements divers et de produire des sons complexes d'une variété illimitée et d'une très grande richesse, mais lesrésultats obtenus sont toujours recombinés pour être diffusés en monophonie ou en stéréophonie. The recent instruments of musical composition make it possible to call upon multiple sources, real instruments, synthetic sounds, various recordings and to produce complex sounds of an unlimited variety and a very great richness, but the results obtained are always combined for be broadcast in monophony or stereophony.
Toutefois, un certain nombre de realisations cinématographiques utilisent des voies multiples afin de recréer un relief sonore proche de la réalité. Mais il s'agit de techniques reservées à des installations très onereuses, non transposables à des productions permettant une diffusion commerciale importante. However, a certain number of cinematographic realizations use multiple ways in order to recreate a sound relief close to reality. However, these are techniques reserved for very expensive installations, which cannot be transposed to productions allowing significant commercial distribution.
Le procédé selon la présente invention supprime toutes ces limitations. En effet, il procure les moyens de composer une ambiance acoustique ayant toutes les caractéristiques de l'ambiance réelle, qu'elle soit musicale ou formée de bruits, en faisant ressentir les déplacements des différentes sources sonores dans toutes les directions, vers le haut ou vers le bas, en avant ou en arrière, vers la droite ou vers la gauche, alors que les methodes connues ne reproduisent que les mouvements latéraux. L'invention offre en outre la possibilité de créer des effets spatiaux ou autres totalement nouveaux, en permettant des fantaisies impossibles à réaliser avec d'autres moyens. The method according to the present invention overcomes all these limitations. Indeed, it provides the means to compose an acoustic environment having all the characteristics of the real environment, whether musical or formed by noises, by making the movements of the different sound sources feel in all directions, upwards or down, forward or backward, to the right or to the left, while the known methods reproduce only the lateral movements. The invention also offers the possibility of creating completely new spatial or other effects, allowing fantasies impossible to achieve with other means.
I1 est caractérisé par la décomposition par echantillonnage de sources sonores quelconques en sons élémentaires qui sont ensuite, au moyen d'un système informatique approprié, envoyés individuellement, au gré du créateur, sur un nombre important de haut-parleurs alimentes par un amplificateur multi-voies et repartis dans l'espace de manière à ce que les auditeurs soient entièrement baignes dans les sonorités produites. It is characterized by the decomposition by sampling of any sound sources into elementary sounds which are then, by means of an appropriate computer system, sent individually, at the discretion of the creator, to a large number of speakers powered by a multi-amplifier. channels and distributed in space so that the listeners are fully immersed in the sounds produced.
La description détaillée ci-après se rapporte à un exemple non limitatif d'une des formes de réalisation de l'objet de l'invention en se référant au dessin schématique annexé. The detailed description below relates to a non-limiting example of one of the embodiments of the object of the invention with reference to the attached schematic drawing.
Le dispositif est constitué d'un ou plusieurs échantillonneurs 1 permettant de décomposer les materiaux sonores utilisés en sons élémentaires et de les stocker en mémoire de manière à pouvoir les utiliser individuellement à la demande. Un système informatique 2 équipé d'un programme de composition musicale, permet d'affecter chaque élément sonore élémentaire à un ou plusieurs canaux indépendants 3 pour le diriger vers un amplificateur multivoies 4, alimentant une serie de haut-parleurs 5. The device consists of one or more samplers 1 making it possible to decompose the sound materials used into elementary sounds and to store them in memory so that they can be used individually on demand. A computer system 2 equipped with a musical composition program makes it possible to assign each elementary sound element to one or more independent channels 3 to direct it to a multi-channel amplifier 4, supplying a series of speakers 5.
Les sources sonores peuvent être de tout type, enregistrement musical sur bande ou disque, synthétiseur, enregistrement direct d'un instrument ou de sons quelconques réalisés à l'aide d'un microphone 6 raccordé à l'échantillonneur 1, etc. The sound sources can be of any type, musical recording on tape or disc, synthesizer, direct recording of an instrument or any sounds made using a microphone 6 connected to the sampler 1, etc.
Les sons élémentaires seront par exemple constitués chacun par une note unique d'un instrument déterminé et auront une durée moyenne de quelques secondes. Ils seront stockés dans une mémoire de masse telle que disquette, bande magnétique ou disque optique, de manière à constituer une bibliotheque organisée de manière à permettre d'extraire indépendemment chacun d'eux au moment souhaité. The elementary sounds will for example each consist of a single note from a given instrument and will have an average duration of a few seconds. They will be stored in a mass memory such as a floppy disk, magnetic tape or optical disk, so as to constitute a library organized so as to allow each of them to be extracted independently at the desired time.
Le système informatique 2, relie aux différentes unites du système par liaisons MIDI, gere l'ensemble grâce à un progamme apte à retrouver dans ladite bibliothèque un son élémentaire déterminé, et à l'envoyer, éventuellement après traitement, vers l'un des haut-parleurs 5, via un canal indépendant 3 et l'un des amplificateurs de l'ensemble multivoies 4. The computer system 2, linked to the various units of the system by MIDI connections, manages the whole thanks to a program able to find in said library a determined elementary sound, and to send it, possibly after processing, to one of the top -speakers 5, via an independent channel 3 and one of the amplifiers of the multi-channel assembly 4.
Cette disposition permet par exemple d'envoyer séquentiellement chaque note d'une mélodie vers un hautparleur 5 différent en donnant ainsi l'impression que l'instrument se déplace en jouant. I1 est bien évident que l'on peut grouper plusieurs instruments, ou transmettre des sons ou bruits de toute nature vers les haut-parleurs de manière à créer des ambiances sonores particulièrement vivantes et réalistes ou au contraire totalement artificielles. This arrangement makes it possible, for example, to send each note of a melody sequentially to a different speaker 5, thus giving the impression that the instrument is moving while playing. It is obvious that one can group several instruments, or transmit sounds or noises of any kind to the speakers so as to create particularly lively and realistic sound atmospheres or on the contrary completely artificial.
Pour obtenir l'effet souhaité, le nombre des haut-parleurs devra être suffisemment important, et autant que possible ne pas être inférieur à huit. To achieve the desired effect, the number of speakers should be large enough, and as much as possible not be less than eight.
Le procédé peut avantageusement être appliqué au moyen d'un dispositif intégré dans un seul boîtier 7, pouvant être portable, et comportant un échantillonneur 1, un ordinateur 2, une mémoire de masse et un amplificateur multivoies 4, ainsi que les connecteurs permettant de raccorder les haut-parleurs 5, le micro 6 et les différentes sources sonores telles que synthétiseur, enregistreur ou autres. Grâce aux possibilités actuelles de miniaturisation et d'intégration et à la baisse constante du coût des composants électroniques, il est parfaitement possible de réaliser un tel appareil à un prix abordable susceptible de lui assurer un importante diffusion. The method can advantageously be applied by means of a device integrated in a single box 7, which can be portable, and comprising a sampler 1, a computer 2, a mass memory and a multichannel amplifier 4, as well as the connectors making it possible to connect the speakers 5, the microphone 6 and the various sound sources such as synthesizer, recorder or others. Thanks to the current possibilities of miniaturization and integration and to the constant fall in the cost of electronic components, it is perfectly possible to produce such a device at an affordable price capable of ensuring wide distribution.
En raison des innombrables possibilités nouvelles qu'ils offrent, le procédé et le dispositif qui viennent d'être decrits sont susceptibles d'ouvrir des marchés très importants dans les domaines de la composition musicale et de la diffusion sonore. Because of the innumerable new possibilities which they offer, the process and the device which have just been described are likely to open very important markets in the fields of musical composition and sound diffusion.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n' avaient pas été, à ce jour, obtenus par des procédés ou dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar methods or devices.
