Sorry WTN but unless you have word clocked your gear to Muris's rig you can not determine accurately whether or not he is 4 % within pitch. Quite simply you do not know the accurate sample sync in comparison with his. There are enough discussion on many forums about the differences in sample rate issues affecting tuning accuracy by a few cents to invalidate any comparison like this IMHO. That is even before any consideration of whether you are both tuned to A=440.

Afraid you can't WTN and so none of us can say accurately whether someone is out by a few cents based solely on a video or mp3 recording. Now if it is a professionally recorded and mastered cd you may because that is the responsibility of the producer to ensure. Interestingly if I put a lot of recordings through software capable of pitch correction - Melodyne and Antares Autotune for instance - it's amazing how much is off pitch by a few cents but 'in tune' relative. And that includes professional commercial cds.
Years ago the situation was 'worse' as lps and tapes could not physically produce a format that was fully accurate across a complicated frequency mix. (Single frequency fine - complicated mix no.) Indeed NO turntable is capable of producing a 100% pitchlock throughout the entire range of travel of an LP. I use a Michell Orbe - a not inexpensive turntable - something that has massive inertia and even Michell acknowledge that on complicated music that the speed can alter particularly as the density of grooves per inch alters with information recorded and as the needle tracks inwards - so changing the drag on the needle. Tape - as we know - similarly suffer from wow and flutter, etc. CDs are also not 100% - one reason why some hi fi bods pay buckets of cash for clock 'accurate' conversion and sync locked tables  . Without a final pro produced cd you need to physically connect a bnc cable to Muris's workclock and yours and check at full sample timing accuracy of his ad/da out and then you can maybe say he's out by a few cents. Seriously I've seen it said an awful lot of times that such and such a recording is out by x, or that someone tunes with a physical tuner and then checks against a computer/digital tuner, whatever - or vice versa - and one is out from the other. Problem is if you don't lock all the kit then you can be out by a few cents frequency or timing wise. Video is particularly an issue here as you run into issues with inaccurate clocking on all but the very high end pro gear - and even there you need to clock. Put it another way - how do you know Muris is a few cents out rather then it being the video recording, running/playing back, or your pc playing back the file at the wrong rate - or some combination? The only real way to know if someone is out a small amount is to plug their guitar in to your Peterson Strobe. On a separate note - I'm a complete Luddite and was always told in studios to 'if in doubt tune to the in-house piano'. I'm such a Luddite that I still use a tuning fork and harmonics to tune if there's no piano .On second thoughts it's because I'm a cheapskate and so won't pay money for a digital/strobe tuner whilst I still have my old and knackerd (and so no longer accurate) tuning forl  .Cheers, Tony -------------------- Get your music professionally mastered by anl AES registered Mastering Engineer.
