Abstract: Systems and methods for identifying the most impactful moments or segments of music, which are those most likely to elicit a chills effect in a human listener. A digital music signal is processed using two or more objective processing metrics that measure acoustic features known to be able to elicit the chills effect. Individual detection events are identified in the output of each metric based on the output being above or below thresholds relative to the overall output. A combination algorithm aggregates concurrent detection events to generate a continuous concurrence data set of the number of concurrent detection events during the music signal, which can be calculated per beat. A phrase detection algorithm can identify impactful segments of the music based on at least one of peaks, peak-proximity, and a moving average of the continuous concurrence data.

Abstract: A system and a method of collectively producing music requires a set of user account that are managed by at least one remote server acting as a hub to exchange ideas and information about a music project. An originator of the music project is able to select other users to specifically collaborate on the music project. The originator and the collaborative users each need to have a user account. A communication platform provides the originator and the collaborative users with a medium to share constructive feedback in real-time about the music project. In addition, the originator and the collaborative users are provided with a set of digital tools that can be found in a modern audio workstation. This allows the originator and the collaborative users to share constructive feedback with each other and then to audibly edit the music project with any tool from the set of digital tools.

Abstract: Systems and methods for rendering motion-audio visualizations to a display are described. More specifically, video data and audio data is obtained. A position of a target object in each of one or more video frames of the video data is determined. Additionally, a video data comprising one or more video frames is determined. Audio visualizations for the predetermined time period are determined based on the frequency spectrum. A rendered video is generated by applying the audio visualizations at the position of the target object in the one or more video frames for the predetermined time period.

Abstract: An audio stream is subjected to speech-to-text processing in order to obtain a textual representation of the audio stream. Hierarchical topic extraction is performed on the textual representation to obtain a multi-level hierarchical topic representation of the textual representation. A user interface actuator is generated, which allows a user to search through the audio stream. Different levels of the multi-level hierarchical topic representation are displayed to the user, based upon the speed of actuation of the user interface actuator.
