Music streaming service in the context of "Podcast"

Streaming media is multimedia delivered through a network for playback using a media player. Media is transferred in a stream of packets from a server to a client and is rendered in real-time or near real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content. Streaming is more commonly used for video on demand, streaming television, and music streaming services over the Internet.

While streaming is most commonly associated with multimedia from a remote server over the Internet, it also includes offline multimedia between devices on a local area network. For example, using DLNA and a home server, or in a personal area network between two devices using Bluetooth (which uses radio waves rather than IP). Online streaming was initially popularized by RealNetworks and Microsoft in the 1990s and has since grown to become the globally most popular method for consuming music and videos, with numerous competing subscription services being offered since the 2010s. Audio streaming to wireless speakers, often using Bluetooth, is another use that has become prevalent during that decade. Live streaming is the real-time delivery of content during production, much as live television broadcasts content via television channels.

A digital music store is a business that sells digital audio files of music recordings over the Internet. Customers gain ownership of a license to use the files, in contrast to a music streaming service, where they listen to recordings without gaining ownership. Customers pay either for each recording or on a subscription basis. Online music stores generally also offer partial streaming previews of songs, with some songs even available for full length listening. They typically show a picture of the album art or of the performer or band for each song. Some online music stores also sell recorded speech files, such as podcasts, and video files of movies.

AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands.

The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received much of the programming previously carried by radio. Later, AM radio's audiences declined greatly due to competition from FM (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming services, and podcasting.

Christian rock is a genre of rock music that features lyrics focusing on matters of Christian faith, often with an emphasis on Jesus. The extent to which their lyrics are explicitly Christian varies between bands. Many bands who perform Christian rock have ties to the contemporary Christian music labels, media outlets, and festivals, while other bands are independent.

In the 1990s and 2000s, Tooth & Nail Records became a catalyst in legitimizing Christian rock as a notable subgenre of alternative rock. Signing acts like Starflyer 59 and MxPx, Tooth & Nail helped make alternative rock immediately accessible within evangelical church communities throughout the United States, and subsequently the wider Western world with the advent of music streaming.

Loudness, K-weighted, relative to full scale (LKFS) is a standard loudness measurement unit used for audio normalization in broadcast television systems and other video and music streaming services.

LKFS is standardized in ITU-R BS.1770. In March 2011, the International Telecommunication Union (ITU) introduced a loudness gate in the second revision of the recommendation, ITU-R BS.1770-2. In August 2012, the ITU released the third revision of this recommendation ITU-R BS.1770-3. In October 2015, the ITU released the fourth revision of this recommendation ITU-R BS.1770-4. In November 2023, the ITU released the fifth revision of this recommendation ITU-R BS.1770-5.

Compact Disc Digital Audio (CDDA or CD-DA), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs. The standard is defined in the Red Book technical specifications, which is why the format is also dubbed "Redbook audio" in some contexts. CDDA utilizes pulse-code modulation (PCM) and uses a 44,100 Hz sampling frequency and 16-bit resolution, and was originally specified to store up to 74 minutes of stereo audio per disc.

The first commercially available audio CD player, the Sony CDP-101, was released in October 1982 in Japan. The format gained worldwide acceptance in 1983–84, selling more than a million CD players in its first two years, to play 22.5 million discs, before overtaking records and cassette tapes to become the dominant standard for commercial music. Peaking around year 2000, the audio CD contracted over the next decade due to rising popularity and revenue from digital downloading, and during the 2010s by digital music streaming, but has remained as one of the primary distribution methods for the music industry. In the United States, phonograph record revenues surpassed the CD in 2020 for the first time since the 1980s, but in other major markets like Japan it remains the premier music format by a distance and in Germany it outsold other physical formats at least fourfold in 2022.
