![]() Its value is 101010, occuring at equal slices of time, represented by the equally-spaced dashed vertical lines. The top waveform represents a theoretically perfect digital signal. Here is how waveform distortion can cause time-base distortion: The two most common causes of jitter are poorly-designed Phase Locked Loops (PLL's) and waveform distortion due to mismatched impedances and/or reflections in the signal path. It is caused by varying time delays in the circuit paths from component to component in the signal path. Is this good? Is it bad? What sonic difference does it make? We will attempt to answer these-and other important-questions in this Section. For example, Digital Domain's FCN-1 Format Converter adds a small amount of jitter (around 200 ps RMS) to the digital audio signal path. All digital devices that have an input and an output can add jitter to the signal path. Jitter is so misunderstood among recording engineers and audiophiles that we have decided to devote a Section to the topic. Some questions that this previous article has raised have been clarified in our letters section, and of course are covered much better in the book. I hesitate to remove this older article from our website, as it is still informative, but I highly recommend that those interested in the latest word on this subject please read the chapter on jitter in my new book. This produced the best copies.ĮVERYTHING YOU ALWAYS WANTED TO KNOW ABOUT JITTER BUT WERE AFRAID TO ASK Finally, we copied from a CD player connected to CDR. I have taken the Master to another Audio Guild member’s house who uses some expensive software. This is about $6 per blank disc and is superior to Black CDs. Original recordings are on Mobile Fidelity gold discs. I am not really wise on copying software. I use software that came with the computer and set copying at 1x. Hi Spearmint, I guess the original recordings are WAV files. If you like you can dump the files onto a DVD and I can give it a try for you. I also have a full SCSI reader and writer which are supposed to be better again although I haven’t done any comparisons. ![]() I copy a lot of my CD tracks and record them on black CD’s and only record at 16x speed so none of the speed stop starts occur with the recorder. Please visit their website for details and online ordering.Hi Mohan, what format are the files saved in? I wonder if it’s the recording software you are using that is causing the degrading of the recording.
