The present disclosure relates to a method and an apparatus for determining a karaoke singing score, and belongs to the technical field of karaoke singing systems. The method includes: capturing a singing audio by an audio capture device upon detection of a karaoke singing instruction to a target song; acquiring a plurality of time units obtained by dividing a preset voice period of the target song; for each time unit, performing time offset adjustment on the time unit based on a preset adjustment duration to obtain at least one offset time unit, determining pitch values corresponding to the time unit and each time offset unit respectively in the captured singing audio, scoring each of the determined pitch values based on a preset reference pitch value of the time unit, and determining the highest score as a score corresponding to the time unit; and determining a total score of the singing audio based on the score corresponding to each time unit. The method and the apparatus have the advantage that scoring accuracy of the singing audio is improved.

Playback, recording, and analysis of music scales via software configuration. In an embodiment, a graphical user interface is generated with staff and keyboard canvases, visually representing a music staff and keyboard, respectively, a scale input, parameter input(s), and a play input. In response to selection of a scale, the staff canvas is updated to visually represent the notes in the scale. In response to the selection of a musical parameter, the staff canvas and/or keyboard canvas are updated to reflect the musical parameter. In response to selection of the play input, a soundtrack of the scale is output, while simultaneously highlighting the note, being played, on the staff canvas and the key, associated with the note being played, on the keyboard canvas.

Embodiments included herein generally relate to managing low frequencies of an output signal. For example, a method may include: measuring a sound pressure level (SPL) of a speaker; dynamically selecting a cutoff frequency for operating a first filter configured to provide a first bass component of a bass element of an output signal and a second filter configured to provide a second bass component of the bass element; providing the cutoff frequency to the first filter to configure the first filter to generate the first bass component based on the cutoff frequency; providing the cutoff frequency to the second filter to configure the second filter to generate the second bass component based on the cutoff frequency; and generating an output signal based on at least one of the first and second bass components.

A method of generating actions following the rhythm of music includes the steps of (a) using an electronic device to classify the sound signals from plural musical instruments into a complex pitch range, (b) the electronic device performing Fourier series conversion on the sound signals of the complex pitch range to obtain plural rhythm diagrams, (c) the electronic device performing a rhythm change point capture action on each rhythm diagram, and then executing no action if the intensity in the rhythm diagram continues to increase with time, or regarding the point as a rhythm change point if the intensity changes from an increase to a decrease, and then transmitting an action signal to an action device, and (c) the action device executing the corresponding action according to the action signal.

Method of generating actions following the rhythm of music includes the steps of (a) using an electronic device to classify the sound signals from plural musical instruments into a complex pitch range, (b) the electronic device selecting at least one pitch range according to the significance of the sound, and then performing Fourier series conversion on the sound signals of the selected said at least one pitch range to obtain at least one rhythm diagram. (c) the electronic device performing a rhythm change point capture action on the rhythm diagram, and then executing no action if the intensity in the rhythm diagram continues to increase with time, or regarding the point as a rhythm change point if the intensity changes from an increase to a decrease, and then transmitting an action signal to an action device, and (c) the action device executing the corresponding action according to the action signal.

A software plug-in module that interfaces to a media editing host application generates and embeds information about a media composition being edited directly within portions of the user interface generated by the host application. The information may include a custom representation of media data of a time-based element of the media composition that replaces, augments, or overlays a timeline representation of the element generated by the host application. Media editing functionality provided by the plug-in may be accessed by an operator based on viewing or interacting with the custom representation. Results of analysis of the media composition by the plug-in may be displayed within the host-generated timeline and used by an operator as a basis for performing edit operations with standard host tools or with plug-in generated tools. Plug-ins may embed their interfaces within user interfaces of host digital audio workstations, non-linear video editing systems, and music notation applications.

This invention is directed to a tone shifting device that includes an analog to digital (A/D) converter configured to receive an audio output from a musical instrument to convert it into a digital signal and to pass it to a computing unit; an input device configured to allow a player to select at least one note to be shifted in real time 10 during playing a musical instrument; a computing unit configured to receive the input signal from the A/D converter and a second input from the input device and to shift a selected note/s to a lower/higher tone in real time during playing; a digital to analog (D/A) converter configured to receive the signals from the computing unit and convert them to analog form; and an amplifier configured to receive the analog 15 signal from said D/A converted and play the played modified music through a loudspeaker of the amplifier. The tone shifting device allow selective shifting of a selected musical note in real time during playing.

A sound synthesizing method according to one aspect of the present disclosure relates to a sound synthesizing method that is realized by a computer, including receiving musical score data and acoustic data via a user interface; and generating, based on respective one of the musical score data and the acoustic data, acoustic features of a sound waveform having a desired timbre.

Methods and systems are described that are utilized for remotely controlling a musical instrument. A first digital record comprising musical instrument digital commands from a first electronic instrument for a first item of music is accessed. The first digital record is transmitted over a network using a network interface to a remote, second electronic instrument for playback to a first user. Optionally, video data is streamed to a display device of a user while the first digital record is played back by the second electronic instrument. A key change command is transmitted over the network using the network interface to the second electronic instrument to cause the second electronic instrument to playback the first digital record for the first item of music in accordance with the key change command. The key change command may be transmitted during the streaming of the video data.

A system and method to generate and implement digital tuning files based on p-smooth number sequences for use with a digital musical instrument is provided. A p-smooth number sequence is generated and a subset of p-smooth numbers from the sequence is chosen as a musical octave of musical note frequencies. Each note within the octave is designated as a tonic, and each tonic is used to generate additional musical octaves and corresponding musical note notations. The musical octaves and corresponding musical note notations are stored into the digital memory of the digital musical instrument, and the instrument's native musical note mappings are remapped to the musical octaves and corresponding musical note notations from the digital file.
