Benifits of Audio Master Quality Recording:

Significantly Reduce Jitter by up to 30%
Audio CDs burned using conventional methods display considerably higher jitter values (audible playback errors) than pressed CDs. The Advanced Audio Master Quality Recording feature reduces jitter values by up to 30% in order to achieve the best possible sound quality from your recorded audio discs. Enjoy improved audible clarity, fuller bass reproduction and improved stereo sound separation.

Improve Playback Compatibility
Not all standalone CD players are designed to play recordable media. Audio Master Quality Recording can help ensure maximum compatibility on the widest range of players. You can also experience less skips on your car or portable CD player.

Long-term readability! [ MORE ]
Because pits and lands are wider, data integrity is more easily secured, helping to maintain readability under conditions where conventional CDs can become corrupted. And Audio Master Quality Recording is not just for music-now also use it with your valuable data to keep it safer for years to come.

How does Audio Master Quality Recording work?
Yamaha's Audio Master Quality Recording dramatically reduces jitter. Using this feature, the recorder will write longer pits and lands than when in standard mode. Thanks to a variable linear speed, CD-players will read CDs created with the feature at the same speed even though pits and lands are considerably longer. The difference is not only technical, but audible as well. This unique recording feature succeeds in a way that traditional CD recording methods have always failed. It brings true-to-press quality to newly created CD-R or CD-RW music discs.

While the CD player's laser unit reads the data, the photo detector covers a wider area per pit or land. The jitter factor remains under 20ns (i.e. very low), or a reduction of up to 30%.

The result: A CD recorded using Audio Master Quality Recording is noticeably better sounding than one recorded using conventional methods. In fact, the quality of audio is nearly equivalent to that of a pressed audio CD. In addition, it is easier for CD-players, including older CD-players and car hi-fi systems, to read music that was recorded using Yamaha's Audio Master Quality Recording mode, resulting in greater compatiblity and fewer skips.

What is Jitter?
A CD-R/RW drive writes audio in the form of pits and lands on the recordable layer of the disc. The digital information in the pits and lands is decoded by the scanning unit in the CD player and played. Various factors (e.g. crystal oscillators, component tolerances, ADCs and DACs frequency mismatch, electromagnetic fields, the inconsistency of the lands and pits‹their length or width and the uneven gaps between them) can prevent these signals from reaching the CD-player's scanning unit at exactly the intended time. This timing inaccuracy is what is known as "jitter".

Jitter: A Graphical Explanation

The top waveform is perceived as a perfect digital signal, the wave definition and timing are theoretically flawless. The lower waveform represents the exact information but with jitter. In contrast, the waveform is distorted and the timing is inaccurate. In the worst case, such jitter can be heard as audible clicks or pops during playback.

Yamaha's Audio Master Quality Recording mode widens pits and lands, significantly reducing jitter during playback. In test after test, listeners proclaim they will never go back to the old way of writing audio CDs again. The results, they say, are astonishing.
