The "Brainwave Digital Encoding and Audio-Visual Playback System" has been granted invention patents in China, the United States, and Taiwan. Its end product is "Yuanshenyin" brainwave music. Originally, the content of "Yuanshenyin" brainwave music, whether "emotional music" (eyes open) or "spiritual music" (eyes closed), was mostly automatically generated by the system, with users only allowed to choose the timbre (instrument) and playback speed (BPM). To allow users more creative expression in their brainwave music, a new "Yuanshenyin" brainwave music creative platform mode has been added. In the creative platform, users can choose the melody, pitch, style, timbre, playback speed (BPM), and accompanying background audio and scene sound effects for their brainwave music. This allows a single piece of brainwave music to produce a myriad of creative effects depending on the selected elements.
