Don't sell yourself short. Pizza, wine and music have smoothed many a rough water.

Seems like a cool guy, clear headed. And he has spent a career dealing with college students, so I doubt stupid remarks bother him much.

Please don't mention gauge invariance, broken symmetry etc. Some of our friends on here might think that explains the claimed phenomenon!

One of the nice things about real physics is that it is much weirder/more wonderful than anything the 'social construct' people can dream up, but they will never enjoy the things we have glimpsed in labs or equations.

I live in Sydney. I would be happy to help run a listening test concerning HDD vs. USB for anyone who is interested.

We need someone who would be open to hosting it for themselves and others at their home (Sydney metro only).

I would suggest the protocol be:
  • HDD version of music.
  • USB version of music.
  • files created as per the earlier claims made on this thread.
  • listeners can listen to the HDD version as much as they like.
  • listeners can listen to the USB version as much as they like.
  • out of sight of the listeners, I will then play either the USB or HDD version.
  • Listeners will then mark whether they are listening to the USB version or the HDD version.
  • The sequence of switching will be based on a random number sequence.
  • At the end of 16 listens, we total up the results.
If anyone is interested, send me a PM.

Who are these dreadfully impoverished 'social contruct people' ? Does Lee Smolin qualify, to offer just one example?

Default Does AIFF files degrade when moved about

Hi sandyk,
Thanks for sharing you discoveries.

Have you noticed if AIFF files degrade when moved about ?
What if the slightly degraded WAV file is recopied to a USB flash drive (with a low noise PS), would that in any way help restore the quality of the file ?

Thanks

What about WavPack? Despite the slow encoding (when set to maximum quality, of course), WavPack is really a favorite of mine. I haven't noticed any degradation over the network or hard drives.

Carz, files are moved about between computers every day with no degrading, if you copy a WAV from one disc to the next the operating system will use the checksums to monitor the copy and it will be exactly the same, otherwise all this (the internet, data storage etc) would not exist. this is one major audiophile fantasy, and a load of ****.
Where does this minor degrading happen, how can it happen, on other threads we have put it down to the dark bits. I copy numerous files from one system to another, via the internet, memory stick, hard drive, none have changed and none have suffered any minor degradation, if the file copies correctly (and the checksum will confirm this) it is an IDENTICAL copy of the original file, no difference whats so ever. Along with power supply noise being recorded with the data, this ranks amongst the craziest audiophile theory's and time would be better spent looking at real problems.

Everything in the digital domain is in a physical format. It might be charge on a little capacitor, or a current present or missing, or a magnetic domain - all physical.

As marce says, a file is a file. IT (and almost everything else) would collapse if data was corrupted in the way that some audiophiles allege. They clearly don't realise how impossible is their silly claim. It is almost like claiming that they put an apple in a bag, wave it around their head, then it turns into an orange - not possible.

Just a few years ago the common wisdom said that it remained perfect, no matter what, but we now know better.
Please explain what you mean by physical format???

Further, I have been asking for years what this minor degradation is, how it come about, how it is recorded with the digital data, as yet I have had not one reply....
