The reference threshold is illustratively an average of spectral variations of a first plurality of audio segments of the plurality of audio segments. In one or more embodiments according to the present application, since a music beat is generally 160 beats per minute or less, that is, 60×1000ms/160=375 ms per beat, a difference value is required for identifying the beat, and a sampling time is required to be less than 375 ms/3=125 ms, and Δt time is required to be less than or equal to 125 ms.

Optionally, in step S220, parsing the audio being played based on the music parsing algorithm includes performing a parsing operation for the audio being played in response to receiving the control request. Optionally, in step S220, parsing the audio being played based on the music parsing algorithm includes one or more of: dividing the audio into a plurality of audio segments at a first time interval; converting the audio time domain information into frequency domain information for each audio segment; intercepting a frequency domain range of interest for each audio segment; calculating the frequency spectrum variation of adjacent audio segments; and generating a control parameter based on the comparison of the spectral variation with the reference threshold.
