Moodbar
Moodbar is a computer visualization used for navigating within a piece of music or any other recording on a digital audio track. This is done with a commonly horizontal bar that is divided into vertical stripes. Each stripe has a colour combination showing the "mood" within a short part of the audio track. The colour can depend on spectrum and/or rhythmic features of the part of the track. If the audio is a song then various parts of it (intro, choruses, solos, accents etc.) as well as changes ( dynamics, rhythm, texture, playing instruments) are differently coloured on the bar. If the audio is a speech or an interview then the moodbar displays different speaking segments in unique colour combinations. Moodbar was originally presented by Gavin Wood and Simon O’Keefe in their paper ''On Techniques for Content-Based Visual Annotation to Aid Intra-Track Music Navigation''. Moodbar has been implemented for Amarok, ClementineStrawberry Music Player and Exaile music players and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clementine (software)
Clementine is a free and open-source audio player. It is a port of Amarok 1.4 to the Qt 4 framework and the GStreamer multimedia framework. It is available for Unix-like, Windows and macOS operating systems. Clementine is released under the terms of the GPL-3.0-or-later. Clementine was created due to the transition from version 1.4 to version 2 of Amarok, and the shift of focus connected with it, which was criticized by many users. The first version of Clementine was released in February 2010. The last stable release of Clementine was in 2016, but development has since resumed on GitHub, with a number of release candidate versions published. In 2018, a fork of Clementine named ''Strawberry Music Player'' was released. Features Clementine has the ability to stream audio from services such as Spotify, SoundCloud and Last.fm, as well as other platforms. The software also has the functionality to display information such as lyrics and statistics regarding the song current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amarok (software)
Amarok is a free and open-source music player. It is available for Unix-like, as well as for Windows and macOS systems. Although Amarok is part of the KDE project, it is released independently of the central KDE Software Compilation release cycle. Amarok is released under the terms of the GPL-2.0-or-later. History The project was originally started by Mark Kretschmann as a means of improving XMMS due to several usability problems, which interfered with the addition of new files to the playlist due to several user interface elements existing for one task. The original amaroK was created based upon the idea of a two-pane interface seen in Midnight Commander, and the first version of the software released solely by Kretschmann, was based upon the ideal of allowing users to drag-and-drop music into an interface in which the playlist was displayed on the right and information on the left. After the initial release of AmaroK, several developers joined the project to form the †... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exaile
Exaile is a cross-platform free and open-source audio player, tag editor and library organizer. It was originally conceived to be similar in style and functions to KDE's Amarok 1.4, but uses the GTK widget toolkit rather than Qt. It is written in Python and utilizes the GStreamer media framework. Exaile incorporates many features from Amarok (and other media players) like automatic fetching of album art, handling of large libraries, lyrics fetching, Last.fm support, advanced tag editing, and optional iPod and MSC device support via plugins. Compared to typical music players, Exaile is able to handle large music libraries without requiring a massive importing of all music files into its own organizational structure. To facilitate this, Exaile allows users to organize their music library in a wide variety of ways, such as by tags, group tags, smart playlists, genre, storage location, and more. In addition, Exaile supports plugins that provide features such as ReplayGain suppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music Genome Project
The Music Genome Project is an effort to "capture the essence of music at the most fundamental level" using various attributes to describe songs and mathematics to connect them together into an interactive map. The Music Genome Project covers five music genres: Pop/Rock, Hip-Hop/Electronica, Jazz, World Music, and Classical. Any given song is represented by approximately 450 "genes" (analogous to trait-determining genes for organisms in the field of genetics). Each gene corresponds to a characteristic of the music, for example, ''gender of lead vocalist'', ''prevalent use of groove'', ''level of distortion on the electric guitar'', ''type of background vocals'', etc. Rock and pop songs have 150 genes, rap songs have 350, and jazz songs have approximately 400. Other genres of music, such as world and classical music, have 300–450 genes. The system depends on a sufficient number of genes to render useful results. Each gene is assigned a number between 0 and 5, in half-integer inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music Visualization
Music visualization or music visualisation, a feature found in electronic music visualizers and media player software, generates animated imagery based on a piece of music. The imagery is usually generated and rendered in real time and in a way synchronized with the music as it is played. Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a number of composited effects. The changes in the music's loudness and frequency spectrum are among the properties used as input to the visualization. Effective music visualization aims to attain a high degree of visual correlation between a musical track's spectral characteristics such as frequency and amplitude and the objects or components of the visual image being rendered and displayed. Definition Music visualization can be defined, in contrast to previous existing pre-generated music plus visualization combinations (as for example music videos), by its ...

Dynamics (music)
In music, the dynamics of a piece is the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings still require interpretation by the performer depending on the musical context: for instance, the ''forte'' marking (meaning loud) in one part of a piece might have quite different objective loudness in another piece or even a different section of the same piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato. Purpose and interpretation Dynamics are one of the expressive elements of music. Used effectively, dynamics help musicians sustain variety and interest in a musical performance, and communicate a particular emotional state or feeling. Dynamic markings are always relative. never indicates a precise level of loudness; it merely indicates that music in a passage so marked should be considerably quieter than . There are ma ...

Rhythm
Rhythm (from Greek , ''rhythmos'', "any regular recurring motion, symmetry") generally means a " movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years. Rhythm is related to and distinguished from pulse, meter, and beats: In the performance arts, rhythm is the timing of events on a human scale; of musical sounds and silences that occur over time, of the steps of a dance, or the meter of spoken language and poetry. In some performing arts, such as hip hop music, the rhythmic delivery of the lyrics is one of the most important elements of the style. Rhythm may also refer to visual presentation, as "timed mov ...

Texture (music)
In music, texture is how the tempo, melodic, and harmonic materials are combined in a musical composition, determining the overall quality of the sound in a piece. The texture is often described in regard to the density, or thickness, and range, or width, between lowest and highest pitches, in relative terms as well as more specifically distinguished according to the number of voices, or parts, and the relationship between these voices (see Common types below). For example, a thick texture contains many 'layers' of instruments. One of these layers could be a string section or another brass. The thickness also is changed by the amount and the richness of the instruments playing the piece. The thickness varies from light to thick. A piece's texture may be changed by the number and character of parts playing at once, the timbre of the instruments or voices playing these parts and the harmony, tempo, and rhythms used. The types categorized by number and relationship of parts are an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acoustic Fingerprint
An acoustic fingerprint is a condensed digital summary, a fingerprint, deterministically generated from an audio signal, that can be used to identify an audio sample or quickly locate similar items in an audio database. Practical uses of acoustic fingerprinting include identifying songs, melodies, tunes, or advertisements; sound effect library management; and video file identification. Media identification using acoustic fingerprints can be used to monitor the use of specific musical works and performances on radio broadcast, records, CDs, streaming media and peer-to-peer networks. This identification has been used in copyright compliance, licensing, and other monetization schemes. Attributes A robust acoustic fingerprint algorithm must take into account the perceptual characteristics of the audio. If two files sound alike to the human ear, their acoustic fingerprints should match, even if their binary representations are quite different. Acoustic fingerprints are not h ...

User Interface Techniques
An interaction technique, user interface technique or input technique is a combination of Computer hardware, hardware and software elements that provides a way for computer users to accomplish a single task. For example, one can go back to the previously visited page on a Web browser by either Point-and-click, clicking a Button (computing), button, pressing a Computer keyboard keys, key, performing a mouse gesture or uttering a Hands-free computing, speech command. It is a widely used term in human-computer interaction. In particular, the term "new interaction technique" is frequently used to introduce a novel user interface design idea. Definition Although there is no general agreement on the exact meaning of the term "interaction technique", the most popular definition is from the computer graphics literature: A more recent variation is: The computing view From the computer's perspective, an interaction technique involves: * One or several input devices that capture u ...

Data Visualization Software
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. Dat ...
