Music Search Engines
An audio search engine is a web-based search engine which Web crawler, crawls the web for Digital audio, audio content. The information can consist of web pages, images, audio files, or another type of document. Various techniques exist for research on these engines. Types of search Audio search from text Text entered into a search bar by the user is compared to the search engine's database. Matching results are accompanied by a brief description of the audio file and its characteristics such as sample frequency, bit rate, type of file, length, duration, or coding type. The user is given the option of downloading the resulting files. Audio search from image The Query by Example (QBE) system is a searching algorithm that uses content-based image retrieval (CBIR). Keywords are generated from the analysed image. These keywords are used to search for audio files in the database. The results of the search are displayed according to the user preferences regarding to the type of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engine
A search engine is a software system that provides hyperlinks to web pages, and other relevant information on World Wide Web, the Web in response to a user's web query, query. The user enters a query in a web browser or a mobile app, and the search engine results page, search results are typically presented as a list of hyperlinks accompanied by textual summaries and images. Users also have the option of limiting a search to specific types of results, such as images, videos, or news. For a search provider, its software engine, engine is part of a distributed computing system that can encompass many data centers throughout the world. The speed and accuracy of an engine's response to a query are based on a complex system of Search engine indexing, indexing that is continuously updated by automated web crawlers. This can include data mining the Computer file, files and databases stored on web servers, although some content is deep web, not accessible to crawlers. There have been ma ...

Spectrogram
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called '' waterfall displays''. Spectrograms are used extensively in the fields of music, linguistics, sonar, radar, speech processing, seismology, ornithology, and others. Spectrograms of audio can be used to identify spoken words phonetically, and to analyse the various calls of animals. A spectrogram can be generated by an optical spectrometer, a bank of band-pass filters, by Fourier transform or by a wavelet transform (in which case it is also known as a scaleogram or scalogram). A spectrogram is usually depicted as a heat map, i.e., as an image with the intensity shown by varying the colour or brightness. Format A common format is a graph with two geometric dimensions: one axis represents time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Search Engine
A video search engine is a web-based search engine which crawls the web for video content. Some video search engines parse externally hosted content while others allow content to be uploaded and hosted on their own servers. Some engines also allow users to search by video format type and by length of the clip. The video search results are usually accompanied by a thumbnail view of the video. Video search engines are computer programs designed to find videos stored on digital devices, either through Internet servers or in storage units from the same computer. These searches can be made through audiovisual indexing, which can extract information from audiovisual material and record it as metadata, which will be tracked by search engines. Utility The main use of these search engines is the increasing creation of audiovisual content and the need to manage it properly. The digitization of audiovisual archives and the establishment of the Internet, has led to large quantities of vid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music Information Retrieval
Music information retrieval (MIR) is the interdisciplinary science of retrieving information from music. Those involved in MIR may have a background in academic musicology, psychoacoustics, psychology, signal processing, informatics, machine learning, optical music recognition, computational intelligence, or some combination of these. Applications Music information retrieval is being used by businesses and academics to categorize, manipulate and even create music. Music classification One of the classical MIR research topics is genre classification, which is categorizing music items into one of the pre-defined genres such as classical, jazz, rock, etc. Mood classification, artist classification, instrument identification, and music tagging are also popular topics. Recommender systems Several recommender systems for music already exist, but surprisingly few are based upon MIR techniques, instead of making use of similarity between users or laborious data compilation.

Search By Sound
Search by sound is the retrieval of information based on audio input. There are a handful of applications, specifically for mobile devices that utilize search by sound. Shazam, Soundhound, Axwave, ACRCloud and others have seen considerable success by using a simple algorithm to match an acoustic fingerprint to a song in a library. These applications take a sample clip of a song, or a user-generated melody and check a music library/ music database to see where the clip matches with the song. From there, song information will be queried and displayed to the user. These kinds of applications are mainly used for finding a song that the user does not already know. Searching by sound is not limited to just identifying songs, but also for identifying melodies, tunes or advertisements, sound library management and video files. Acoustic fingerprinting The way these apps search by sound is through generating an acoustic fingerprint; a digital summary of the sound. A microphone is ...

Multimedia Search Engine
Multimedia is a form of communication that uses a combination of different content forms, such as writing, audio, images, animations, or video, into a single presentation. This is in contrast to traditional mass media, such as printed material or audio recordings, which only feature one form of media content. Popular examples of multimedia include video podcasts, audio slideshows, and animated videos. Creating multimedia content involves the application of the principles of effective interactive communication. The five main building blocks of multimedia are text, image, audio, video, and animation. Multimedia encompasses various types of content, each serving different purposes: * Text - Fundamental to multimedia, providing context and information. * Audio - Includes music, sound effects, and voiceovers that enhance the experience. Recent developments include spatial audio and advanced sound design. * Images - Static visual content, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humming
A hum ( /hʌm/ ) Latin: murmur, The sound of giraffes humming () is a sound made by producing a wordless tone with the mouth closed, forcing the sound to emerge from the nose. To hum is to produce such a sound, often with a melody. It is also associated with thoughtful absorption, 'hmm'. A hum has a particular timbre (or sound quality), usually a monotone or with slightly varying tones. There are other similar sounds not produced by human singing that are also called hums, as the sound produced by machinery in operation, such as a microwave, or by an insect in flight. The hummingbird was named for the sound that bird makes in flight which sounds like a hum. Mechanics A 'hum' or 'humming' by humans is created by the resonance of air in various parts of passages in the head and throat, in the act of breathing. The 'hum' that a hummingbird creates is also created by resonance: in this case by air resistance against wings in the actions of flying, especially of hovering. H ...

Singing
Singing is the art of creating music with the voice. It is the oldest form of musical expression, and the human voice can be considered the first musical instrument. The definition of singing varies across sources. Some sources define singing as the act of creating musical sounds with the voice. Other common definitions include "the utterance of words or sounds in tuneful succession" or "the production of musical tones by means of the human voice". A person whose profession is singing is called a singer or a vocalist (in jazz or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung accompaniment, with or a cappella, without accompaniment by musical instruments. Singing is often done in an ensemble (music), ensemble of musicians, such as a choir. Singers may perform as Soloist (music), soloists or accompanied by anything from a single instrument (as in art songs or some Jazz, jazz styles) up to a symphony orchestra or big band. Many styles o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
