sound
Audio in DirectAnimation is represented by the SoundBvr (DASound) class. Sound can be imported from WAV or MIDI files, synthesized by mixing multiple sine waves, or constructed by rendering a geometry with embedded sounds into a single microphone for a single channel sound, or into two microphones for stereo sound. Microphones are implemented in DirectAnimation by the MicrophoneBvr (DAMicrophone) class.

Operations on sounds include SoundBvr.loop (DASound.Loop ), SoundBvr.gain (DASound.Gain), SoundBvr.rate (DASound.Rate), SoundBvr.phase (DASound.Phase), SoundBvr.pan (DASound.Pan), and SoundBvr.mix (DASound.Mix).

spline
A polynomial function that follows defining points. The defining points can carry different weights. DirectAnimation supports B-splines through the NumberBvr, Point2Bvr, Point3Bvr, Vector2Bvr, and Vector3Bvr class method bSpline, and through the DAStatics function CubicBSplinePath and the Statics method cubicBSplinePath.
sprite
A 2-D image that can move over a background without disturbing it. In DirectAnimation, sprites are images operated on by the ImageBvr.transform (DAImage.Transform) method.
