What is a word clock in recording?
In digital audio electronics, a word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio signals.
What is a word clock generator?
A word-clock generator will centralize all of the timing of various pieces of digital equipment, reducing accumulated timing errors between the individual units that make up a digital recording chain.
How do you insert a clock in Word?
Use a coaxial BNC cable (75 Ω) to connect the external word clock to the Wordclock In input. A suitable cable is available as an accessory part. See „Antenna cables“. Connect the Wordclock In input of the next EM 6000 to the Wordclock Out output of the previous EM 6000.
What is an audio master clock?
An external clock connects to your audio interface (or other digital gear) using word clock connections, typically using BNC cables — the external clock becomes the “master” and sends the clock signal via a word clock output, while the audio interface (for example) becomes the “slave” and receives clock using a word …
What is the time speaking clock?
A speaking clock or talking clock is a live or recorded human voice service, usually accessed by telephone, that gives the correct time. The first telephone speaking clock service was introduced in France, in association with the Paris Observatory, on 14 February 1933.
What frequency is word clock?
Word clock is a set of timed pulses used to synchronize signals at the clock rate, which is called the sampling frequency or sample rate (at a value typically in the kilohertz range; e.g., 44.1kHz, 48kHz, 88.2kHz, 96kHz, etc.). Word clock is used by the receiving digital device to lock to the incoming digital signal.
Can ADAT carry word clock?
By contrast, AES3, S/PDIF and ADAT all embed the clock pulses within the audio stream by using a type of modulation process.
What is World clock in audio?
A word clock isn’t necessarily a device, but rather a data stream that is sent between audio devices so that they stay in sync with a constant, precisely-timed bitrate. The word clock signal doesn’t contain any other data.
Does the speaking clock still exist 2020?
Everyone used to know the number for the speaking clock, it’s 123, but today few young people will even know it exists. But the service – known as Talkline – still gets more than 30 million calls a year despite the rush to embrace new technology, with demand peaking on four timesensitive days.
Is the speaking clock still operating?
The Speaking Clock is still an emblem of accuracy to some people, which might explain why they’re still prepared to pay for it, says Rory McEvoy, a curator of horology at the Royal Observatory Greenwich. In 1936, when the speaking clock was introduced, people were reliant on mechanical clocks, says McEvoy.
Why is word clock necessary?
At its simplest, then, the clock identifies when each sample should be recorded or replayed — and we call that a ‘word clock’ — but in practice, it often also provides other useful information, such as identifying each encoded audio channel in multi-channel systems.
How does a word clock converter work on a digital clock?
Typically, you would allocate one converter as the ‘word-clock master’ (switched to operate at the required sample rate), and connect its word-clock output to the word-clock input of the next unit, which would be switched to reference the external clock.
Why is a word clock called a sample clock?
A word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio signals. Word clock is so named because it clocks each audio sample. Samples are represented in data words.
Which is master clock format does word clock use?
S/PDIF, AES/EBU, ADAT, and TDIF are some of the formats that use a word clock. Various audio over Ethernet systems use communication protocols to distribute word clock. The device which generates the word clock is the only master clock source for all the slave audio devices.
What does word clock on Pro Tools HD do?
Every digital device, from a simple portable CD player to a Pro Tools HD rig, has a word clock. Not to be confused with sync clock (like MTC or SMPTE), word clock is what tells a A/D or D/A converter when to take the sample. It fires an impulse to the converter 44.1k (or 48k, or 96k, etc) times per second.
