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 ...

Shazam (music App)
Shazam is an application that can identify music based on a short sample played using the microphone on the device. It was created by the British company Shazam Entertainment, based in London, and has been owned by Apple since 2018. The software is available for Android, macOS, iOS, Wear OS, watchOS and as a Google Chrome extension. The original UK developer of the app, Shazam Entertainment Limited, was founded in 1999 by Chris Barton, Philip Inghelbrecht, Avery Wang, and Dhiraj Mukherjee. On 24 September 2018, the company was acquired by Apple for a reported $400 million. Overview Shazam identifies songs using an audio fingerprint based on a time-frequency graph called a spectrogram. It uses a smartphone or computer's built-in microphone to gather a brief sample of the audio being played. Shazam stores a catalogue of audio fingerprints in a database. The user records a song for 10 seconds and the application creates an audio fingerprint. Shazam works by analyzing the cap ...

Sound Library Management
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evok ... [...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.

Lostwave
Lostwave is a term for music with little to no information available about their origins, including song titles, names of associated musicians, and recording and release dates. Lostwave songs have been the subject of online crowdsourced efforts to uncover their origins. History Lostwave originated mainly from the search for " The Most Mysterious Song on the Internet", recorded from the German radio station Norddeutscher Rundfunk (NDR) in the mid-1980s, likely in or after 1984, by Darius S. In 2007, Darius' sister, Lydia H., uploaded the song to best-of-80s.de and The Spirit of Radio, sparking widespread interest across various Internet forums. In 2024, the song was identified as "Subways of Your Mind" by German new wave band Fex. With other examples of lostwave appearing online, a Reddit community of the same name was created in 2019 to distinguish it from the search for "The Most Mysterious Song on the Internet" and bring more attention to the topic. This was the first usage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Online Music Databases
Below is a table of online music databases that are largely free of charge. Many of the sites provide a specialized service or focus on a particular music genre. Some of these operate as an online music store or purchase referral service in some capacity. Among the sites that have information on the largest number of entities are those sites that focus on discographies of composing and performing artists. Performance rights organisations typically have their own databases as per country they represent, in accordance with Confédération Internationale des Sociétés d'Auteurs et Compositeurs, to help domestic artists collect royalties. Information available on these portals include songwriting credits, publishing percentage splits, and alternate titles for different distribution channels. It is one of the most accurate and official types of databases because it involves direct communication between the artists, record labels, distributors, legal teams, publishers and a global gov ...

Automatic Content Recognition
Automatic content recognition (ACR) is a technology used to identify content played on a media device or presented within a media file. Devices with ACR can allow for the collection of content consumption information automatically at the screen or speaker level itself, without any user-based input or search efforts. This information may be collected for purposes such as personalized advertising, content recommendations, or sale to companies that aggregate customer data. How it works To start the process, a short media clip (audio, video, or both) is selected from within a media file or captured as displayed on a device such as a smart TV. Using techniques such as fingerprinting and watermarking, the selected content is compared by the ACR software with a database of known recorded works. If the fingerprint of the media clip finds a match, the ACR software returns the corresponding metadata regarding the media as well as other associated or recommended content back to the client a ...

AmpliFIND
AmpliFIND is an acoustic fingerprinting service and a software development kit developed by the US company MusicIP. MusicIP first marketed their fingerprinting algorithm and service as MusicDNS. In 2006, MusicIP reported that the MusicDNS database had more than 22 million fingerprints of digital audio recordings. One of their customers was MetaBrainz Foundation, a non-profit company that used MusicDNS in their MusicBrainz and MusicBrainz Picard software products. Even so, MusicIP dissolved in 2008. The company's CEO, Andrew Stess, bought the rights to MusicDNS, renamed the software to ''AmpliFIND'', and started a new company called AmpliFIND Music Services. In 2011, Stess sold AmpliFIND to Sony, who incorporated it into the digital music service offerings of their Gracenote division. Tribune Media subsequently purchased Gracenote, including the MusicDNS software. How MusicDNS identifies a recording To use the MusicDNS service, software developers write a computer program t ...

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 or whistled 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, Tunebot and Google Search.

Video Files
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types. Video systems vary in display resolution, aspect ratio, refresh rate, color capabilities, and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcasts, magnetic tape, optical discs, computer files, and network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mechanical video scanners, such as the Nipkow disk, were patented as early as 1884, however, it took several decades b ...

Advertisements
Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to present a product or service in terms of utility, advantages, and qualities of interest to consumers. It is typically used to promote a specific good or service, but there are a wide range of uses, the most common being commercial advertisement. Commercial advertisements often seek to generate increased consumption of their products or services through " branding", which associates a product name or image with certain qualities in the minds of consumers. On the other hand, ads that intend to elicit an immediate sale are known as direct-response advertising. Non-commercial entities that advertise more than consumer products or services include political parties, interest groups, religious organizations, and governmental agencies. Non-profit organizations may use free modes of persuasion, such as a public service announcement. Advertising may also help ...
