Atomic master clocks at their best

Digital audio means a very precise math involved in every aspect of this artistic, yet very fixed field. Frequencies, sample rates, binary information all the way, everything relies on a very precise basis of actually calculating exact portions of whatever is at stake: make one mistake and whole projects can fall apart in just seconds.

This is why hi-tech audio equipment must also work on extremely precise runtimes if extreme quality and accurate response is desired as a result of the undertaken actions. When working in a studio, people usually have lots of interconnected digital gear which must be in perfect synchronization if the best output is wanted.

Actually the last years in the audio industry were also centered in eliminating the time losses in the most intimate places of the technological flow of generic audio processing. Standards like ASIO/2 are more and more exact and try to rid the audio processing process of un-sync and de-phased elements. And to do this, all digital equipment must run referring to the same internal clock so that everything in perfect sync and timing.

Antelope Audio is a company which grew specialized in constructing some of the world's most accurate an precise clocking devices known to man: atomic clocks. Their latest release, the Isochrone 10M promises up to 8 days of PERFECT timing; try and compare this performance with the common crystal oscillators which lose one sample per second while at 98kHz! What would happen if they were required to "vibe" at 192 kHz?

For those who don't know, the moment a digital audio sampling operation loses sync leads to the birth of jitter. Jitter is best described as the inconsistency in the audible sound resembling a CD/vinyl scratch. Most digital players sport a jitter correction options but they are far from repairing the damage done by bad digital sampling.

Well, there is no more need for jitter correction if you plan to use the Isochrone: the steady and constant pulses emitted by its oscillating Rubidium core will ensure your timing is absolutely perfect (at least for 8 days in a row). While most similar oscillators are heavily affected by temperature changes, the new Antelope Audio Isochrone 10M has an internal "oven" which makes sure that temperature values stay as they should be - no need to worry!

Connecting this atomic master clock to the digital gear in your studio ensures the perfection of any sampling or generally speaking time-related process you might need to carry out. And if I'll just add that it is perfect for gearboxing video formats in the ever expanding HDTV world what would you say? Simply connect your input to a PAL connection and burst 96kHz out the NTSC way.

Simple and intuitive commands will allow the unskilled or even unaware users to get to operate the Isochrone 10M in just moments. Once you can rest assured you won't be losing any sample while you work you can concentrate on the more creative sides of your audio, rather than worrying about precise math. And as I say rest assured I really meant it: the Antelope Audio Isocohrone 10M is a 0.03 ppB device: it will "lose" 0.03 samples during the sampling of 1 billion such "parts". Enough accuracy? How about the quite affordable price of $2,200?
