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.

A method for detecting audio signal beat points of a bass drum, and a terminal. The method comprises: acquiring several intrinsic mode functions based on an inputted audio signal to be detected; calculating instantaneous signals, wherein the instantaneous signals includes instantaneous strength signals and instantaneous frequency signals corresponding to the several intrinsic mode functions; acquiring characteristic signals of the bass drum based on the instantaneous strength signals and the instantaneous frequency signals corresponding to the several intrinsic mode functions; performing peak detection on the characteristic signals to acquire a plurality of peak points; and acquiring the beat points of the bass drum based on the plurality of peak points.

[Technical problem] Circulatory sound regulation that changes environmental sound into input sound, converted sound with arbitrarily regulatory frequency component, arbitrarily regulatory amplitude or both of them, output sound, another input sound synthesized with this output sound and an environmental sound, and another converted sound made from this input sound. [Solution] Apparatus comprising: input means that receives environmental sound from arbitrary environment as an input sound; conversion means that converts the input sound into a converted sound that contains arbitrarily regulatory frequency component including frequency component that approximates to principle oscillator, arbitrarily regulatory amplitude or both; and output means that transmits the converted sound to environment as an output sound; whereby the input means receives synthetic sound synthesized with the output sound and environmental sound as an input sound again, and the conversion means converts this input sound further into another converted sound.

A low complexity howling suppression system and method for portable karaoke system are provided. In the howling suppression, at least one infinite impulse response (IIR) filters are introduced for estimating the acoustic feedback picked up by the microphone from the real environment, and thereby to cancel out the acoustic feedback from the microphone input signal.
