BAD MOVE POSTING SERIAL NUMBERS! You might find your Fuze is already registered by someone who bought a busted unit on Ebay!

 

 

It would be pointless for someone to register their Fuze with a different serial number than the one printed on their unit, because if the serial stealer sends their Fuze in for repair, Sandisk will see that the serial number on the unit doesn't match the serial number they registered. Right?

When are you going to buy one and test it? You want everyone else to test theirs when you don't even have one Smiley Tongue


 

Touche! :smileytongue: But I do think that it makes more sense to research a product before buying it, than for one who already owns the product to put his head in the sand when he hears that it may be defective. Especially if he works in a modern recording studio, he should understand that 0.7% is significant. Try pitching up or down any one of the clients' files, then passing it off as "finished."  Then you'll see how big of a deal it is! (and probably lose a client too)

Different test method, similar results.

 

I used an Agilent 53181A (with opt 001, med. stab. oven) to measure the frequency of the player's output directly. The counter was  calibrated by Agilent last September - i.e. it's in cal.

 

I generated 10kHz tones in Audacity at 44.1k & 48k sample rates. I used 10kHz rather than 1kHz because the more transitions the better for frequency counters.

 

I tried 44.1k first, generating MP3 CBR, MP3 VBR, and FLAC versions.

 

I loaded the files to these players:

 

 Fuze v1 01.01.22F

 e260 v2 03.01.16A (not FLAC)

 

Both players produced a measured output frequency of 10.069kHz regardless of file encoding. (The observant among you will note that the 53181A has 10 digits. Not surprisingly, only the MS 5 were stable, so I left the rest off.)

 

I then generated a VBR file from a 10kHz tone at a 48k sample rate. I didn't bother with other formats, as the 44.1k test showed no sensitivity to encoding type.

 

Both players generated a measured output of 10.044kHz.

 

Both players use AMS hardware, so I suppose the similarity in results is not surprising. 

 

It would be intersting to try other players...

 

In retrospect, I should have measured the PC's output for interest's sake. Maybe I'll try that later. Better do some work now Smiley Happy

Thanks Daytona!  Your test using files of a 44.1 kHz Sample Rate is very interesting.  I haven't asked people to perform that test here due to the possibility that by providing two test files, people may get them mixed up and thus create a lot of con(FUZE?)ion.  Once this thread fills up, I will create another one using a 48 kHz test file.

 

I'm surprised that your Fuze is off pitch when playing 48kHz files too!  :smileysurprised:

Fine I will make my defenc one last time. I dont believe it is productive for someone to go around makeing problems where there are none. This as I said is a nonissue in my book. If we had hundreds of people on here saying "Hey my fuze plays funny" then ok we can pursue it, but instead 3 or 4 people came on and said something and now you are asking otherwise happy users to test their player and are then telling them how far off it is. It seems counterproductive and dare I say trollish. I work in the most modern studios in the US and none of us here can hear a difference against orgional recordings. If you want to waste a bunch of time ruining peoples experice and scaring people away from the player then you can go a head. But I will not be a part of it. And as for me Burrying my head in the sand... I prefer to be a productive member of the boards, and atually help people not investigate an issue that 6 people noticed before this witch hunt started. I agree with Marvin, Max go out and buy yourself a fuze and test it. IF its sooo far of that you feel like you need to have your ears replaced just return it. There I said my peace, I am done with this.

Do Ipods or Zunes have perfect playback?
4 GB Red Fuze, Black Silicon Case, Red JVC Marshmallow Headphones. A 1 GB m240 as well, those were the days.

Thank you so much CB for saying what so many of us must be thinking.This cats thread has been disingenuous from the start.This whole subject has been a crock and the OP's motivations are deeply suspect and must be called into question.Well done CB.

Whoa, hold it for a second.   The wording of your first post (ie "Please help us", "We are using this information..." ) led me to believe you were doing this test solely for the purpose of helping Sandisk/Sansa identify and potentially fixing the slow (or fast) playback issue, NOT to help you determine whether or not you wanted to buy the player.

I probably would have helped out either way, but your (intentionally?) misleading word choice irks me.

lol are you guys kidding?  It's mostly serious musicians (people who play) who I've seen posting complaints.  If they play a properly tuned musical instrument along with their Fuze, the net result is obviously out of tune, and useless. 

 

In addition, people with the ability to measure the problem have confirmed that it exists, on a whole greater order of magnitude than with the other devices measured.

So the Clip's pitch error (and presumably play speed error) is over 20x worse than my other portables, and 200x worse than the difference between my CD player and DVD player.

My fuze was replaced by a new Sony NWZ-e438f that reproduces tracks precisely on pitch and at identical speed to the same tracks played on all of my other devices.


 

I don't think that Arranger has run the test with his Sony, I'd be interested to see the results of that test.  However, since he's a musician who plays a properly tuned instrument along with his player, and who detected the Fuze's off pitch playback with his ears in that situation, I think that he's probably right about the Sony playing back on pitch.  BUT, to be certain, let's see his test results. Arranger, do you mind performing the test for us, and uploading the file so we can all verify the results?

 

 

If you think the people who have identified, quantified, and complained about this problem are disingenuous, then you must be disingenius.

 

If you are so confident that your Fuze plays back on pitch, then why not prove it? I would like to see how far this problem extends, so far I have yet to see a test run on a Fuze which didn't indicate this problem was occurring. Run the test, and post a link to your file here.
