A computer user interface (UI) is capable of generating a sound when a predetermined event occurs. The sound generated when the predetermined event occurs may possess at least some characteristics of a predominant natural language used by a user and/or a location of a computer implementing the UI. This enables the user to quickly assimilate the sound generated when the predetermined event occurs. Because the user quickly assimilates the sound generated when the predetermined event occurs, the user is able to rapidly respond to the predetermined event, at times using the computer UI, which reduces undesirable memory use, processor use and/or battery drain associated with a computing device that implements the computer UI.

Systems and methods for generating a haptic output from an audio signal having a continuous stream of sampled digital audio data are provided. A haptic processing system receives the digital audio data, analyses the digital audio data for processing and extracts haptic signals for generating a haptic effect through an actuator. The method includes passing the digital audio signal on through dynamic processor(s), adjusting the dynamic range of the digital audio signal, extracting the signal envelope of the audio data, synthesising low-frequency signals from the extracted signal envelope, and enhancing the low-frequency content using a resonator. The haptic output is generated by mixing the digital audio signal with outputs from the different modules of the haptic processing system. An analytics module monitors, controls and adjusts the processing of the digital audio signal at the noise gate module, the compressor module and the envelope module to enhance the haptic output.

Techniques for automatically controlling the expressive behavior of a virtual musical instrument by analyzing an audio recording of a live musician are provided. In some embodiments, an audio recording may be analyzed at various points along the timeline of the recording to derive corresponding values of a parameter that is in some way representative of the musical expression of the live musician. Values of control parameters that control one or more aspects of the audio playback of a virtual instrument may then be generated based on the determined values of the expression parameter. Values of control parameters may be provided to a sample library to control how a digital score selects and/or plays back samples from the library, and/or values of the control parameters may be stored with the digital score for subsequent playback.
