Disclosed are a method and apparatus for displaying music points, and an electronic device and a medium. One specific embodiment of the method includes: acquiring audio material; analyzing initial music points in the audio material, wherein the initial music points include beat points and/or note starting points in the audio material; and on an operation interface of video clipping, displaying, according to the position of the audio material on a clip timeline and the positions of target music points in the audio material, identifiers of the target music points on the clip timeline, wherein the target music points are some of or all of the initial music points. According to the embodiment, the time for a user to process audio material and to make music points is reduced, and the flexibility of tools is also guaranteed.

In implementations of searching for music, a music search system can receive a music search request that includes a music file including music content. The music search system can also receive a selected musical attribute from a plurality of musical attributes. The music search system includes a music search application that can generate musical features of the music content, where a respective one or more of the musical features correspond to a respective one of the musical attributes. The music search application can then compare the musical features that correspond to the selected musical attribute to audio features of audio files, and determine similar audio files to the music file based on the comparison of the musical features to the audio features of the audio files.

In an electronic device for an electronic musical instrument, a determination grace period during which a plurality of operations on the electronic musical instrument by a user are determined to be simultaneously performed for the first section is set based on the data included in a first section of the song having a plurality of sections. Automatic accompaniment is advanced from the first section to the next second section when a user operation of the electronic musical instrument is detected outside of the determination grace period for the first section during the playback of the first section of the accompaniment, and automatic accompaniment is not advanced from the first section to the second section when the user operation of the electronic musical instrument is detected within the determination grace period for the first section during the playback of the first section of the accompaniment.

Musical catalog amplification services that leverage or deploy a computer-based musical composition system are described. The computer-based musical composition system employs algorithms and, optionally, artificial intelligence to generate new music based on analyses of existing music. The new music may be wholly distinctive from, or may include musical variations of, the existing music. Rights in the new music generated by the computer-based musical composition system are granted to the rights holder(s) of the existing music. In this way, the musical catalog(s) of the rights holder(s) is/are amplified to include additional music assets. The computer-based musical composition system may be tuned so that the new music sounds more like, or less like, the existing music of the rights holder(s). Revenues generated from the new music are shared between the musical catalog amplification service provider and the rights holder(s).

A method for flattening power of a musical sound signal, said method being characterized by comprising: determining second values corresponding to respective first values indicating power at a plurality of time points of a musical sound signal each on the basis of the result of a comparison between the present value of the first value and the present value of the second value; and flattening the plurality of first values using the second values corresponding to the plurality of first values, respectively, wherein the second value changes while drawing a predetermined trajectory when, in the result of the comparison, a state where the present value of the second value is larger than the present value of the first value continues.

The present invention relates to a method for processing and playing audio data comprising the steps of receiving mixed input data and playing recombined output data. Furthermore, the invention relates to a device 10 for processing and playing audio data, preferably DJ equipment, comprising an audio input unit for receiving a mixed input signal, a recombination unit 32 and a playing unit 34 for playing recombined output data. In addition, the present invention relates to a method and a device for representing audio data, i.e. on a display.

Provided a method for playing audios. The method includes: acquiring vibration control information corresponding to a target audio, wherein at least one vibration period and vibration attribute information corresponding to the at least one vibration period are recorded in the vibration control information, and each vibration period corresponds to a beat period of a target percussive instrument in the target audio; synchronously playing the target audio and the vibration control information; and when any vibration period of the at least one vibration period is played, controlling a terminal to vibrate based on vibration attribute information corresponding to the vibration period.

Systems and methods are provided and include a computing device that receives a selection of a song available for streaming from the music streaming server and transmits a query to the music streaming service server for a musical attribute associated with the selected song. The computing device receives the musical attribute and determines a paint color associated with the selected song based on the musical attribute. The computing device displays the determined paint color and a name and identification code of the paint color on a display of the computing device. The computing device outputs the selected song to a speaker of the computing device while displaying the determined paint color on the display of the at least one computing device.

A method for synchronizing a pre-recorded music accompaniment to a music playing of a user. The music playing is captured by at least one microphone, which delivers an input acoustic signal feeding a processing unit, which includes a memory for storing data of the music accompaniment and provides an output acoustic signal based on the music accompaniment data to feed at least a loudspeaker playing the music accompaniment. The processing unit analyses the input acoustic signal to detect musical events and music tempo, compares the detected musical events to the music accompaniment data to determine at least a lag between the timings of the detected musical events and the musical events of the music accompaniment, and adapts a timing of the output acoustic signal based on the lag and a synchronization function calculated from a temporal variable, the user's music tempo, and the duration of compensation of the lag.

A method for tuning a managed pressure drilling system comprising a variable orifice choke to control fluid flow from a drilling well includes (a) characterizing change in flow rate through the choke with respect to choke opening at a substantially constant pressure drop; (b) characterizing change in fluid pressure in the well with respect to change in choke opening at a substantially constant flow rate into the well; (c) characterizing a response time of pressure in the well to changes in the choke opening, a delay time of pressure response after a change in choke opening and a back pressure applied to the well with respect to choke opening. The characterizations in at least one of (a) and (b), and the characterization in (c) are used as control parameters for a proportional integral differential controller having as output the choke opening and as input the fluid pressure in the well before the choke.
