Query By Humming
Query by humming (QbH) is a music retrieval system that branches off the original classification systems of title, artist, composer, and genre. It normally applies to songs or other music with a distinct single theme or melody. The system involves taking a user-hummed melody (input query) and comparing it to an existing database. The system then returns a ranked list of music closest to the input query. One example of this would be a system involving a portable media player with a built-in microphone that allows for faster searching through media files. The MPEG-7 standard includes provisions for QbH music searches. Examples of QbH systems include ACRCloud, SoundHound, Musipedia, and Tunebot.

Music Information Retrieval
Music information retrieval (MIR) is the interdisciplinary science of retrieving information from music. MIR is a small but growing field of research with many real-world applications. 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 MIR is being used by businesses and academics to categorize, manipulate and even create music. Music classification One of the classical MIR research topic is genre classification, which is categorizing music items into one of 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 making use of similarity betwe ...

MPEG-7
MPEG-7 is a multimedia content description standard. It was standardized in ISO/ IEC 15938 (Multimedia content description interface). This description will be associated with the content itself, to allow fast and efficient searching for material that is of interest to the user. MPEG-7 is formally called ''Multimedia Content Description Interface''. Thus, it is ''not'' a standard which deals with the actual encoding of moving pictures and audio, like MPEG-1, MPEG-2 and MPEG-4. It uses XML to store metadata, and can be attached to timecode in order to tag particular events, or synchronise lyrics to a song, for example. It was designed to standardize: * a set of Description Schemes ("DS") and Descriptors ("D") * a language to specify these schemes, called the Description Definition Language ("DDL") * a scheme for coding the description The combination of MPEG-4 and MPEG-7 has been sometimes referred to as MPEG-47.

Acoustic Fingerprinting
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 ...

D-Lib Magazine
''D-Lib Magazine'' was an online magazine dedicated to digital library research and development. Past issues are available free of charge. The publication was financially supported by contributions from the D-Lib Alliance. Prior to April 2006, the magazine was sponsored by the Defense Advanced Research Project Agency (DARPA) on behalf of the Digital Libraries Initiative and by the National Science Foundation (NSF). Despite its important role in shaping the then emerging digital library community, ''D-Lib Magazine'' eventually folded due in part to an unsustainable funding model, the maturity of the field, and the rise of social media and blogs. After 22 years, 265 issues and 1062 articles ''D-Lib Magazine'' ceased publication in July 2017. ''D-Lib Magazine'' was innovative in many ways, including: HTML-only publishing (no PDF versions), open access, and use of persistent identifiers for articles (the Handle System and later DOIs (which are implemented using the Handle System Th ...

Tunebot
Tunebot is a music search engine developed by the Interactive Audio Lab at Northwestern University. Users can search the database by humming or singing a melody into a microphone, playing the melody on a virtual keyboard, or by typing some of the lyrics. This allows users to finally identify that song that was stuck in their head. Searching techniques Tunebot is a query by humming system. It compares a sung query to a database of musical themes by using the intervals between each note. This allows a user to sing in a different key than the target recording and still produce a match. The intervals are also unquantized to allow for other tunings besides the standard A=440Hz, since not many people in the world have perfect pitch. In addition to note intervals, Tunebot compares a query with potential targets by using rhythmic ratios between notes. Since ratios between note lengths are used, the tempo of the performance does not affect the rhythmic similarity measure. Queries and ta ...

Digital Media
Digital media is any communication media that operate in conjunction with various encoded machine-readable data formats. Digital media can be created, viewed, distributed, modified, listened to, and preserved on a digital electronics device. ''Digital'' defines as any data represented by a series of digits, and ''media'' refers to methods of broadcasting or communicating this information. Together, ''digital media'' refers to mediums of digitized information broadcast through a screen and/or a speaker. This also includes text, audio, video, and graphics that are transmitted over the internet for viewing or listening to on the internet. Digital media platforms, such as YouTube, Vimeo, and Twitch, accounted for viewership rates of 27.9 billion hours in 2020. A contributing factor to its part in what is commonly referred to as ''the digital revolution'' can be attributed to the use of interconnectivity.

Melody
A melody (from Greek language, Greek μελῳδία, ''melōidía'', "singing, chanting"), also tune, voice or line, is a Linearity#Music, linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of pitch (music), pitch and rhythm, while more figuratively, the term can include other musical elements such as Timbre, tonal color. It is the foreground to the background accompaniment. A line or part (music), part need not be a foreground melody. Melodies often consist of one or more musical Phrase (music), phrases or Motif (music), motifs, and are usually repeated throughout a musical composition, composition in various forms. Melodies may also be described by their melodic motion or the pitches or the interval (music), intervals between pitches (predominantly steps and skips, conjunct or disjunct or with further restrictions), pitch range, tension (music), tension and release, continuity and coheren ...

Search Engine Technology
A search engine is an information retrieval software program that discovers, crawls, transforms and stores information for retrieval and presentation in response to user queries. A search engine normally consists of four components, that are search interface, crawler (also known as a spider or bot), indexer, and database. The crawler traverses a document collection, deconstructs document text, and assigns surrogates for storage in the search engine index. Online search engines store images, link data and metadata for the document as well. History of Search Technology The Memex The concept of hypertext and a memory extension originates from an article that was published in The Atlantic Monthly in July 1945 written by Vannevar Bush, titled As We May Think. Within this article Vannevar urged scientists to work together to help build a body of knowledge for all mankind. He then proposed the idea of a virtually limitless, fast, reliable, extensible, associative memory storage and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material.
