Speaker objects.

The speaker object is used to give sound in the 3D Viewport. After adding the object, the various settings can be changed in the Properties.

Opciones

Sonido

Abrir

The Menú Bloque de Datos for loading audio files. There are two properties you can check when loading a sound:

Caché

This means the whole sound will be decoded and the raw audio data will be buffered in memory, which results in faster playback, but uses quite a lot of memory. So this should be used for short sound effects that get played more often, but not for longer audio files such as music.

Mono

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.

Silenciar

Toggles whether or not the sound can be heard.

Volumen

Adjust the loudness of the sound.

Inclinación

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.

Distance

Speaker properties.

Distance attenuation relevant settings.

Volumen

Minimum/Maximum

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

Attenuation

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).

Distance

Máximo

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.

Referencia

The distance at which the volume is full (1.0). Set this value to the distance used for recording the sound. Usually sound effects recordings should be made exactly 1 m away from sound to get an accurate volume.

Cono

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 is no directionality anymore. Inside the inner cone the volume is full (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.

Ángulo

Outer

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

Inner

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

Volumen

Outer

Volume outside the outer cone.
