Objets Speaker.

L’objet Speaker est utilisé pour fournir le son dans la Vue 3D. Après l’ajout de l’objet, les divers réglages peuvent être modifiés dans l’Éditeur Properties.




The Menu data-block for loading audio files. There are two properties you can check when loading a sound:




For any 3D audio or panning effects the sound source has to be single channel, otherwise it’s assumed that the 3D audio and panning information is already present in the multichannel file. Enable this if you want to use those effects for a file with multiple channels.


Indique si le son peut être entendu ou non.


Ajuste le niveau sonore.


Can be used to bend the pitch of the sound to be either deeper or higher. This basically changes the playback speed of the sound which also results in a pitch change.

Playback Time

There is no setting to choose the start time when the speaker should start playing, because you might want a single speaker to play multiple times. Therefore you have to open the NLA Editor where you can add sound strips that define when the sound should start (nothing else, so any other properties of the strips, like length don’t matter). When you add a speaker object such a strip will be added at the current frame. The Shortcut to add a strip in the NLA Editor is Shift-K.



Speaker properties.

Distance attenuation relevant settings.


No matter how far away/close the object is, the distance-based volume won’t be lower/higher than this value.


How strong the distance affects the volume. This factor sets the strength of the distance-based volume change, depending on the chosen distance model (see scene settings).


If the object is farther away than this distance, this distance is used to calculate the distance-based volume. Influence of this value also depends on the distance model.




Directionality relevant settings.

Imagine a cone with the top at the original of the speaker object and the main axis of it facing in the same direction as the speaker. There are two cones an inner and an outer cone. The angles represent their opening angles, so 360° mean the cone is fully open and there’s no directionality anymore. Inside the inner cone the volume is 100% (1.0), outside the outer cone the volume is, whatever one sets for the outer cone volume and the volume between those two cones, linearly interpolated between this two volumes.


Angle of the outer cone in degrees. Outside this cone, the volume is equal to the Outer volume.


Angle of the inner cone in degrees. Inside the cone, the volume is 100%.


Volume en dehors du cône extérieur.
