InMotion 3D Audio Producer is an advanced spatial sound processing and encoding tool for anyone involved in audio production. InMotion allows musicians, sound designers, audio production studios, and Web page designers to create stunning 3D audio presentations for playback over conventional stereo loudspeakers. Listeners will experience sound coming from all directions including the front, read, and extreme left/right. The user simply positions the sound around the listener or draws the path that the sound should follow. InMotion supports an unlimited number of sound sources. Powerful time-line sequencing allows complex scenes to be created with ease. InMotion features state-of-the-art environmental modeling capabilities (including 3D positioning, professional quality reverberation, doppler motion effects, air absorption and occlusion modeling, and crosstalk cancellation), real-time parameter updates, and virtual surround mixing. The system works in real-time by processing a standard stereo sound stream and synthesizing virtual speakers to enhance the stereo sound field.
