My ears agree with the above results -

1: No difference
2: No difference
3: No difference

Although there *are* differences between each of the sample pairs, this can be attributed to

- The samples were MP3 compressed, and some MP3 compression artifacts can be heard
- The recording process. I'm assuming you just connected the player's output to the input of the computer's sound card (which model? integrated or separate?); most common computer sound cards don't have a very high S/N ratio so the result has some noise introduced.
- Other noise sources in the environment (your monitor, printer, scanner, cell phone, television, etc.)

Try recording the same sample multiple times and compare the resulting (uncompressed) files in a sound editor after aligning them; you'll find they do differ by what looks like a significant amount. Now if someone else did the same, and told you one set was recorded after freezing the player/holding it upside-down for 24 hours/sleeping with it/etc. you might believe that was what caused the difference! :D

Again, any PHP members please ignore this post.

Well, this topic could go on forever. What i'm trying to say is that in the 3 before files, there is "something" distinct about them. And the 3 after files, the distinct sounding "thing" is gone. Again, i want to stress that i do not have any professional/scientific equipment to do the tests.

lolita , you're probably talking in a scientific way to analyse the output files. But was the Pepsi & Coke taste test done using equipment to analyse the 2 drinks? No, it was done by having people tasting with their tastebuds.

So what i'm trying to say is, listen to the beginning of the 6 samples. You Will notice a difference of 3 samples having "something", and 3 samples which do not have the "thing". And it just so coincides with the before and after sequence recordings. Too much of a coincidence.

These two samples are the ones which prove that the freezing method actually works.

Before: http://www.savefile.com/files/595126
After: http://www.savefile.com/files/595129

Analyze the waveforms, but you don't even need to do that, as the background noise in the "before" sample is clearly noticeable, while in the "after" sample it's all gone.

And if you argue that it may have something to do with the compression algorithms or audio input to the computer, if you're the kind of guy who has $20000+ worth of audiophile equipment and listens to music in HD-DVD format, then you're not the kind of guy who should have anything to do with MPx players in the first place.

I mean i can hear the compression artifacts in MP3s with bitrates lower than 192kbps even on my C-Media CMI8738 soundcard hooked to an amp and a pair of speakers which aren't worth more than $250, but a MPx player's audio quality is much, much lower, and compression artifacts in MP3 audio are the least thing to worry about.

Yet, these nifty little devices actually play music, and that's what they were designed for. If you aren't happy with yours then go buy a higher quality player like an Archos or an Iriver, and stop bitching about us here, we're just trying to get a little bit more out of our cheapo players. ;)

Anybody can help?
I am looking in eBay for a freezer enough small to be carried in my backpack in order to keep my chipod freeze.
Enclosed is the smaller I've get

Small freezer

It's not enough small... the car battery needed is the main problem
any suggestion?

PS.: I wonder if I found a way to connect my chipod battery to the can freezer :roll:

Gosh!! my mouse get freeze :evil:

Just put it in the regular freezer when you can go without it a couple of days. Mine went from the freezer, to the refrigerator, to wrapped in a towel until I was certain there was no moisture.

DaremoS , why would you want to freeze/cool your player on the go?

Well, he would probably put a few beers in there as well. :D

Ok guys the thing goes this way...

If you have see my freezer it can hold a can freeze all the time, the idea is to put my MP4, not the Meizu nor the Teclast... the one I have for tests, between the can and the freezer, I suppose that the LDX LD-696 will be freeze for ever... producing the best sound... according with posted messages in this thread.

I believe that this theory applies very well to cds as I've read in some other eccentric forums. Anyway today after a pot breakfast I'm on the mood to try this method.

All the apparels can go in my backpack, of course with a cushion to not freeze my back.... the car battery of 12v must be carried in a small wheel cart to provide energy.

The other option is to load .FLAC files in my device instead of MP3 in order to have the best sound ripped from a freeze cd.

Not forgetting to use my best earphones, the really unknown Korean Cresyn LMX-E630
