CD Quality Is Not High-Res Audio

[mep]

Details matter, mep. So does honesty. Here's your straw man:

I suppose everyone should buy the cheapest products available that look the worst compared to their competition and there should be no pride of ownership and then you would be satisfied? Oh, and let's not forget to perform double-blind testing on all components before we buy them.

straw man...actually that's a pretty polite term for it. What's well-documented here is that I am very skeptical of high-end/audiophile claims and conventional wisdoms, and that I believe the science of audio, including measurements, the Nyquist theory and the results of the rare DBX, are probably significantly more credible than what many people think they hear with their eyes wide open and their biases fully engaged. Your characterization of that is, as always, duplicitous.

Why is it now that when someone says something that someone doesn't like they get accused of a strawman argument? In reality, what i said was a tongue-in-cheek response to this:

Yes. Of course it pales compared to the expectation bias created by high-dollar investment, fat cables, shiny boxes and denial of all technical data that disagrees with wishful thinking.Tim

Since you seem to take so much pleasure poking audiophiles in the eye who believe there actually are higher levels of resolution to be had in the home and you waste no opportunity to challenge all who believe in gear and have the audacity to enjoy the looks of their gear as well, I hereby nominate you to be the official sheriff of WBF in charge of prevention of enjoyment of high-end systems. I think you have clearly earned that title.

They don't; they get accused of a strawman argument when they create an absurd or exaggerated position that the other side hasn't actually taken, and attribute it to them....

...and there you did it again. Just joking this time, too?

...And what is your own title Mark?

Does any WBF member know of a site where I can get a 24/44.1 and a 24/96 test track having a -90dB 1000 Hz signal? (Yes, I know I can generate it, but a good friend borrowed my Korg for a few days).

Does any WBF member know of a site where I can get a 24/44.1 and a 24/96 test track having a -90dB 1Hz signal?

Use SoX? Just out of curiosity, what do you need a -90 dB 1Hz signal for?

Sorry it was a typo - I missed typing the "k". Just edited my post!

OK, makes a bit of a difference

You could definitely use SoX to generate the tone, but choice of dithering or not dithering becomes rather essential, because I guess what you want is basically a 1-bit signal?

I have the 1 bit dithered signal using 16 bits in a CD track , I hope that in 24 bit file format people give me more bits ...

To generate 60 seconds of 1 kHz sine wave at 24/96, amplitude -90 dB:

sox -c 2 -r96k -n out.flac synth 60 sine 1000 gain -90

To generate 60 seconds of 1 kHz sine wave at 24/44.1, amplitude -90 dB:

sox -c 2 -r44100 -n out.flac synth 60 sine 1000 gain -90

If you don't have sox on your system, PM me, and I can send you the files.

Thanks. I installed SOX in windows XP and I tried running it in command mode. I get the following error message:

Some helper program or library missing. Maybe try with out.wav instead of out.flac?

Thanks - wav worked perfectly. Can I ask you what is the switch in the command line that controls the number of bits that is used per sample? I should have learned about Sox before, it seems a very useful software. My next task will be creating a 50 Hz stereo file with one channel out of phase by 90 degrees. I usually create these files digitally recording the analog output of a digital generator (!), but this program seems a better way of doing it.

Great! The "number of bits" option is -b, so -b 16 gives you 16 bits per sample.

I think the label "the Swiss Army knife of audio manipulation" is not out of place.

My next task will be creating a 50 Hz stereo file with one channel out of phase by 90 degrees.

This should do it:

sox -c 2 -r48000 -n out.wav synth 60 sine 50 delay 240s 0

It generates a 24/48 file with a 50 Hz sine wave with a one channel with a phase offset of 240 samples (90 degrees of 50 Hz at 48k) for the first channel, and 0 for the second.

Thanks again - I will try it later.

BTW, I own a Victorinox Explorer but it was useless in this task . Perhaps they do not have a model for sound engineers because the ear cleaner would not be acceptable!

Ah, yes. I think they did one that had some USB storage, but I am not sure it was audiphile quality.

 

[Phelonious Ponk]

OK...how did the toothpick become politically incorrect?

Yes, it is audiophile quality, although expensive - surely if you have 1 Tbyte and 22 MB/s you can afford HiREZ

It was my mistake - it seems it was only a false rumor on the net - they still sell the knives with the plastic toothpick.
