The present disclosure provides a method for chorus mixing, an apparatus, an electronic device and storage media. The method includes converting a main vocal audio signal and a chorus audio signal into signals in frequency domain, respectively, wherein the chorus audio signal comprises main vocal audio played by a speaker; determining a delay between the main vocal audio signal and the chorus audio signal based on a frequency-domain signal of the main vocal audio signal and a frequency-domain signal of the main vocal audio played by the speaker included in a frequency-domain signal of the chorus audio signal; aligning the chorus audio signal with the main vocal audio signal based on the determined delay; performing an echo cancellation on the aligned chorus audio signal; and mixing audio of the main vocal audio signal and the echo-canceled chorus audio signal.

A method of determining on a computer-based system at least one representative segment of a musical composition, the method including providing a digital audio signal representing said musical composition; dividing said digital audio signal into a plurality of frames of equal frame duration; calculating at least one audio feature value for each frame by analyzing the digital audio signal, said audio feature being a numerical representation of a musical characteristic of said digital audio signal, with a numerical value equal to or higher than zero; identifying at least one representative frame corresponding to a maximum value of said audio feature; and determining at least one representative segment of the digital audio signal with a predefined segment duration, the starting point of said at least one representative segment being a representative frame.

A method, apparatus and system that enables a user to find and act-upon a sound-containing composition, in a group of compositions. One or more sound-segments, which are intended to prompt a user's memory, may be associated with each composition in a group of compositions. A recognition sound-segment may include a portion of its associated composition, which is more recognizable to users than the beginning part of its associated composition. A recognition-segment may contain one or more highly recognizable portion(s) of a composition. When the user is trying to locate or select a particular composition, the recognition-segments are navigated and played-back to the user, based upon a user-device context/mode. When a user recognizes the desired composition from its recognition-segment, the user may initiate a control action to playback; arrange; and/or act-upon, the composition that is associated with the currently playing recognition-segment.

A system determines human recognizable labels for portions of an electronic media stream, gathers data associated with the electronic media stream from a number of media players, and determines at least one section of the electronic media stream with a particular media feature. The system selects a representative clip for the electronic media stream based on information regarding the labeled portions, the gathered data, and the at least one section.
