A method and apparatus to reproduce stereo sound, which generates optimal stereo sound designed for individual auditory properties. The method includes generating a one or more virtual surround filters corresponding to each of a plurality of head-related transfer functions (HRTFs) classified according to one or more individual auditory properties, generating stereo sound for the one or more virtual surround filters, and selecting at least one from the one or more virtual surround filters, and reproducing the stereo sound based on a filter value of the selected at least one virtual surround filter.

A wearable cardiac defibrillator (“WCD”) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a speaker system that transmits a sound designed to assist a bystander to perform CPR. Optionally CPR chest compressions received by the patient can be further detected, and feedback can be given. In embodiments, a WCD system may include a user interface that can be controlled to output CPR prompts tailored to a skill level of the bystander.

This invention discloses a method and a system providing ring-back service to PABX including: a user small exchanger receives the call request from a calling user by a called party exchanger, the PABX restrains traditional ring-back sounds and sends extension ring inform information with the called number to the called exchanger, which picks up the called number and sends call successive information to the ring-back server after receiving the ring inform information, the server inquires about the ring-back sound designed by the called number and informs the called exchanger to play it to the calling user.

This present invention creates a method of amplitude processing of audio signals, primarily but not exclusively for musical and sound designing purposes. This invention detects the amplitude variations and constancies of a controlling input signal or signals and generates corresponding variations and constancies in another input signal or signals to a specific degree and in a specific manner or combination of manners of operation, at the control of various parameters, rendering a unique and innovative audio effect without changing any frequency content of any signals in the function of the amplitude regulation. This method of amplitude control shall be called amplitude regulation, or amplitude inducing; thus, the invention is titled Indux Dynamics Inducer.

The invention relates to an active sound simulation device based on a Void-Kalman filter. The active sound simulation device comprises an FPGA active sound design module, an MCU control sound production module and a PC host computer; the FPGA active sound design module mainly using the Void-Kalman filter to extract the order signal of engine sound source, and the extracted order signal is downloaded to the MCU control module through an SPI interface in real time. At that same time, the FPGA active sound design module receives a parameter signal of the MCU control sound production module through the SPI interface; the MCU control sound production module is used for completing and controlling the real-time generation of the simulated engine sound according to the order signal extracted by the FPGA active sound design module. The PC host computer downloads the control data from the FPGA active sound design module, and requests and receives the data sent by the FPGA active sound design module. The device uses the Void-Kalman filter to extract the sound order signal, and the MCU master control module controls the sound generation to obtain sound rich in change, which can remind the pedestrian, reduce the safety hidden danger, and lets the driver feel the pleasure of driving.
