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.

An electronic musical instrument according to one aspect of the invention is configured to generate, in response to an excitation signal corresponding to a specified pitch, a first string signal to be output from one of right and left channels based on a first accumulated signal in which outputs of at least a first closed-loop circuit and a second closed-loop circuit among the first closed-loop circuit, the second closed-loop circuit and a third closed-loop circuit, which are provided to correspond to the specified pitch, are accumulated, and generate a second string signal to be output from the other channel based on a second accumulated signal in which outputs of the second closed-loop circuit and the third closed-loop circuit are accumulated.

Embodiments described provide a method for mixing vocal performances from different vocalists. A vocal score temporally synchronized with a corresponding backing track and lyrics is retrieved via a communications interface of a portable computing device. A first vocal performance of a user is captured, via a microphone interface of the portable computing device, and in correspondence with the backing track. An open call indication for soliciting, from a second vocalist, a second vocal performance to be mixed for audible rendering with the first vocal performance is transmitted. A mix to one of the user and the second vocalist is provided by selecting, based on to whom the mix is provided, the mix from alternative mixes each having a different prominent vocal performance.

The intelligent accompaniment generating system includes an input module, an analysis module, a generation module and a musical equipment. The input module is configured to receive a musical pattern signal derived from a raw signal. The analysis module is configured to analyze the musical pattern signal to extract a set of audio features, wherein the input module is configured to transmit the musical pattern signal to the analysis module. The generation module is configured to obtain a playing assistance information having an accompaniment pattern from the analysis module, wherein the accompaniment pattern has at least two parts having different onsets therebetween, and each onsets of the at least two parts is generated by an algorithm according to the set of audio features. The musical equipment includes a digital amplifier configured to output an accompaniment signal according to the accompaniment pattern.

When a harmony function is on state, a generator determines a chord based on one or more notes of depressed keys in a chord kea area, automatically generates one or more additional notes having pitches which harmonizes the pitch of the note of the depressed key in a performance key area according to the determined chord, and inputs the “note of the pressed key in the performance key area+additional notes” to an assignment controller. The assignment controller assigns plural parts (timbres) to the inputted notes, and sounds the notes in timbres of the plural parts according to the assignment. That is, tone generation assignment process is performed regarding not only notes according to performance operation by a user but also automatically generated additional notes.
