A video-audio system and video-audio interactive method are provided. The video-audio system includes a displaying device, a processing device, and an audio device. The displaying device is configured to display a user interface. A handwriting pattern is input in the user interface. The processing device communicatively connect with the displaying device. The processing device is configured to generate an information of sheet music. The information of sheet music corresponds to the handwriting pattern. The audio device is communicatively coupled to the displaying device and the processing device. The user interface has a playing and controlling area. The playing and controlling area has a playing audio button. The audio device is configured to play sounds corresponding to the information of the sheet music when the playing audio button is operated.

An integrated system and method that provides users with non-destructive ways of manipulating musical scores and or audio recordings for student practise, testing and assessment. The said integrated system and method allows users to create questions that utilise one or more of the manipulated items, present questions to a student, collect the said students answer and assess the said students answer. The said integrated system is delivered via digital devices including computers, tablets, smartphones and other such devices.

One embodiment provides a system, method, and device for capturing inaudible tones from content. Content is received. Inaudible tones in the content are detected. Information associated with the inaudible tones of the content is extracted. Information associated with the inaudible tones is communicated to one or more devices. One or more actions associated with the information extracted from the inaudible tones is automatically implemented utilizing the one or more devices.

Systems, methods, and computer program products for audio- and video-editing are provided. A reference file comprising a visual representation of a final audio/video project may be displayed. The visual representation can be musical notation rather than a wave form or a printed movie script rather than video content. A user may determine a first selection and the program may display a list of recordings in which at least a portion of this first selected section occurs. A user may click each line on the list to play each recording cued to the first selected section. The user may choose the best recording. The user may determine a second selection and similarly may choose the best recording of second section. Finally, the program may allow the user to splice both chosen recordings together.

According to embodiments of the present disclosure, systems, methods, and computer program products for audio- and video-editing are provided. A reference file comprising a visual representation (e.g., musical score) of a final video/audio product is read and displayed to a user. A plurality of sections (e.g., measures) and a plurality of symbols (e.g., notes) are determined. A plurality of audio/video recordings are read where each recording corresponding to at least a portion of the visual representation. For each of the plurality of sections, a corresponding segment of at least one of the plurality of audio/video recordings is determined. First selections of a section of the plurality of sections are received from the user. For each of the first selections, a listing of the plurality of audio/video recordings in which at least a portion of the selected section occurs is displayed to the user. For each of the first selections, a second selection of an audio/video recording from the listing is received from the user thereby linking the selected section to the corresponding segment of the selected audio/video recording. An audio/video file is generated by combining each of the linked segments.
