The method includes: dividing the acquired game audio signal into frequency bands; extracting transient feature parameters to characterize the transient changes in the audio signal within the high-frequency band; performing multi-dimensional fusion judgment based on the transient feature parameters to identify whether there are transient audio events with auditory stimulation risks in the high-frequency band audio signal, and determining the audio signal as transient high-frequency harsh sound when a preset judgment condition is met; determining a dynamic suppression threshold based on the occurrence status information of the transient high-frequency harsh sound in the time dimension; implementing dynamic suppression processing on the target high-frequency band when the loudness of the transient high-frequency harsh sound exceeds the dynamic suppression threshold, and compensating for key positioning sound effects in the mid-high frequency band.

A method, system, and medium for affective music recommendation and composition. A listener's current affective state and target affective state are identified, and an audio stream, such as a music playlist, is generated with the intent of effecting a controlled trajectory of the listener's affective state from the current state to the target state. The audio stream is generated by a machine learning system trained using data from the listener and / or other users indicating the effectiveness of specific audio segments, or audio segments having specific features, in effecting the desired affective trajectory. The audio stream is presented to the user as an auditory stimulus. The machine learning system may be updated based on the affective state changes induced in the listener after exposure to the auditory stimulus. The machine learning system may also be used to compose, master, and / or adapt music configured to induce specific affective responses in listeners.

A dry-fire training system and method that uses multiple types of cues (e.g., visual and audible stimuli) presented to the trainee within a predetermined time, preferably simultaneously. The system includes a control application that communicates with one or more targets, each target having light emitting devices capable of displaying different colors and light sensors. The application commands the targets to display different colors to the trainee, along with playing different sounds. One combination of visual stimuli (e.g., a specific color, like “red”) and audible stimuli (e.g., a specific sound, like a “car horn” or “bell”) is a “trigger condition.” Based on whether the trainee, using either a traditional firearm equipped with a laser-emitting cartridge or a simulated firearm that only emits a laser, “shoots” the target, the system determines with the result is a “valid shoot,” a “miss,” or a “bad shoot.”

A method and system for augmented neurorehabilitation (ANR) for patients are disclosed. The ANR system generates rhythmic auditory stimuli (RAS) and visual augmented reality (AR) scenes, which are synchronized according to a common beat speed and output to the patient during a treatment session. Sensors worn by the patient capture biomechanical data related to repetitive movements performed by the patient in sync with the AR visual content and RAS. Critical thinking algorithms analyze the sensor data to determine the spatial and temporal relationships of the patient's movements relative to the visual and audio elements, and to determine the patient's entrainment level and progress toward clinical / therapeutic goals. Furthermore, a 3DAR modeling module configures the processor to dynamically adjust the augmented reality visual and audio content output to the patient based on the determined entrainment level and whether training goals have been achieved.

This invention provides a linked repeat timer that can impart psychoactive effects to the user. [Solution] The linked repeat timer includes a first display unit 550 that displays a first timing time which repeatedly measures a first predetermined time, and a second display unit 560 that works in conjunction with the first display unit to display a second timing time which repeatedly measures a second predetermined time in units of 1 / 60th of a second or 1 / 3600th of a second. With this linked repeat timer, the coordinated operation of the timing displayed on the first display unit and the second display unit in units of 1 / 60th of a second or 1 / 3600th of a second presents rhythmic auditory stimulation through the generation of sound effects with adjusted presentation intervals, allowing the user to receive stimulation from the sound effects and predict the timing of the next sound effect to be presented, thereby imparting psychotropic effects such as anti-anxiety, hypnotic, and anti-delusional effects to the user.
