REQ: Lesound: AudioTexture

There are enormous creative possibilities with AudioTexture: use one simple sound and generate layered sounds with multiple instances of AudioTexture, or use several sound files with multiple instances of AudioTexture to compose a sound scene.

Unique Descriptor Control
AudioTexture comes with 3 descriptor controls in addition to the position control. This is convenient to create various unit sequences based on perceptually meaningful descriptors.

Energy: Instantaneous energy.
Noisiness: The amount of high-frequency content.
Brightness: The spectral energy center, higher the value brighter the sound.
