• Open

Load a sound file. There are two properties you can check when loading a sound (see Sound Load).:

Cache: This means the whole sound will be decoded on load 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. So if you want to use those effects for a file with multiple channels, check this!

• Mute

Mute the speaker.

• Volume

Animatable with I key on the button. How loud the sound is.

• Pitch

Animatable with I key on the button. Playback pitch of the sound.

Distance

Volume

• Minimum

No matter how far the object is away, the distance based volume won't be lower than this value.

• Maximum

No matter how close the object is, the distance based volume won't be higher than this value.

• Attenuation

This factor changes the strength of the distance based volume change, depending on the chosen distance model (See Scene Sound).

Distance

• Maximum

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.

• Reference

The distance at which the volume is 100 % (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.
