Word Sync
Word sync is a technique for synchronizing digital audio signals between high-end professional devices; such as CD players, audio I/O cards, etc. It allows all the components in the signal path to process the data and remain synchronized with each other. Crucial to the operation of simultaneous audio systems, Word sync and other forms of audio synchronization are critical in maintaining timing consistency between different streams of audio data. For standard audio equipment, minute differences in tempo or timing related to multiple sources of audio may appear unnoticeable to the ear in practice, but when isolated in an audio editing environment, or operating within a complex and multifaceted audio system, it can quickly become 'muddy' or deduce the quality of the output. ''E.g.'' ''One drummer is beating out a pattern 10110. But if two or three drummers are also beating that same 10110 pattern but do not all start at exactly the same point in time, or keep exactly the same tempo ...

Digital Audio
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced analog audio technology in many areas of audio engineering, record production and telecommunications in the 1990s and 2000s In a digital audio system, an analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital signal, typically using pulse-code modulation (PCM). This digital signal can then be recorded, edited, modified, and copied using computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweetwater Sound
Sweetwater is the largest online retailer of musical instruments and pro audio equipment in the United States, based out of Fort Wayne, Indiana. In August 2021, it was announced that its founder had stepped down as CEO after Providence Equity had become the majority shareholder of Sweetwater Sound. History Chuck Surack established the company in 1979 in Fort Wayne, Indiana so that he could stop being a touring musician. The company originally offered recording services via a remote recording studio in Surack's Volkswagen microbus and a recording studio based out of his home. In 1985, to increase the services the recording studio could offer, Surack bought a Kurzweil K250, and became known for his custom K250 sound library and programming skills as well as his upgrade kits. Sweetwater became a Kurzweil dealer, but the company's clients were asking for advice regarding other products as well, so Surack expanded Sweetwater to become a retailer of musical instruments and pro audio e ...

Audio Engineering Society
The Audio Engineering Society (AES) is a professional body for engineers, scientists, other individuals with an interest or involvement in the professional audio industry. The membership largely comprises engineers developing devices or products for audio, and persons working in audio content production. It also includes acousticians, audiologists, academics, and those in other disciplines related to audio. The AES is the only worldwide professional society devoted exclusively to audio technology. Established in 1948, the Society develops, reviews and publishes engineering standards for the audio and related media industries, and produces the AES Conventions, which are held twice a year alternating between Europe and the US. The AES and individual regional or national ''sections'' also hold ''AES Conferences'' on different topics during the year. History The idea of a society dedicated solely to audio engineering had been discussed for some time before the first meeting, but was ...

Syncword
In computer networks, a syncword, sync character, sync sequence or preamble is used to synchronize a data transmission by indicating the end of header information and the start of data. The syncword is a known sequence of data used to identify the start of a frame, and is also called ''reference signal'' or ''midamble'' in wireless communications. Prefix codes allow unambiguous identification of synchronization sequences and may serve as self-synchronizing code. Examples In an audio receiver receiving a bit stream of data, an example of a syncword is 0x0B77 for an AC-3 encoded stream. An Ethernet packet with the Ethernet preamble, 56 bits of alternating 1 and 0 bits, allowing the receiver to synchronize its clock to the transmitter, followed by a one-octet start frame delimiter byte and then the header. All USB packets begin with a sync field (8 bits long at low speed, 32 bits long at high speed) used to synchronize the receiver's clock to the transmitter's clock. A rece ...

Musical Tuning
In music, there are two common meanings for tuning: * Tuning practice, the act of tuning an instrument or voice. * Tuning systems, the various systems of pitches used to tune an instrument, and their theoretical bases. Tuning practice Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz. The term "''out of tune''" refers to a pitch/tone that is either too high (sharp) or too low (flat) in relation to a given reference pitch. While an instrument might be in tune relative to its own range of notes, it may not be considered 'in tune' if it does not match the chosen reference pitch. Some instruments become 'out of tune' with temperature, humidity, damage, or simply time, and must be readjusted or repaired. Different methods of sound production require different methods of adjustment: * Tuning to a pitch with one's voic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
