Component audibility. Fact or fiction ?

I downloaded the file (the directors cut has it got rythmm and soul) and played thru the hand phone. All I got was big noise with the music playing on background. I played the file streaming from iPod and quick time with intermittent sound, the music is not in the background of any big noise. I don't understand what happen with the download process.

What did you use to listen to it here Jay ?

Hehe that's pure vocals for tube lovers. I have some CDs with that song, I bought when I was a tube amp user 🙂
 
The problem is not in the download, but in your (very) cheap sound device. They cannot play all wav files and there are plenty of wav files. I have already deleted this one, but as I remember it was a 32 bit wav with 16 bit content, and it made your system sound like noise.

Thanks for the new lesson.

Its ipod and quicktime. Unfortunately i dont know how to download files with ipod. I think i need the jailbreak or something.

The noisy one was with samsung hp with android.

But both of them sound better than the $300 laptop i borrowed few days ago.
 
I assume we should open a new category of threads dedicated to testing via smartphones. Wow.
I have tested mine few weeks ago.

OK 🙂

Another question for all of you.

If you were buying a new audio component such as a preamp or a CD player or speakers even, how would you make your choice ? If its by listening then I'll give you a clue... have another listen to the file. Listen around 9 seconds in, around 30 seconds in, around 1 minute in and around 1:20 in. Those four points put you in the middle of different source components, however there are only three individual source components in the test. One appears twice.

Not so bad perhaps in an absolute sense... does that include distortion from any output stages Pavel or is that a line level output (as a non smartphone person I know nothing of these things 😀)

It is VERY bad. All those high order distortion components and very high noise level. Remember, the noise is computed over 20kHz band, you cannot evaluate only one point of the narrow band spectral analysis. Please do not want for me to explain bin width, narrow band analysis and overall rms noise over audio band, as this is going over and over.

Not output stage only, definitely digital artifacts as well.
 
I've never actually purchased any of my gear based on listening tests!! It's either been off specs, off reviews, or on special 😀

Until I started doing these tests I honestly didn't think I'd be able to hear the difference between a chain of Opamps and electrolytic coupling caps and a straight piece of wire (as I'd done this before and been bitterly disapointed that I didn't hear any difference, even sighted!!) Now I'm not so sure, and I have a feeling I might have better hearing ability than I thought.

Tony.

I look at it this way. Do the same analysis on say a well aligned Nakamichi. Lots of noise, and with Dolby C noise pumping, tons of distortion particularly at LF, all the bad things of a mechanical system... but which will "sound" the best... the Nakamichi or the phone.

Its "badness" in different ways. I know its unrealistic comparing an analogue source with a digital one but on face value those digital artefacts are low, non look over -90db. Many a CD player would sound awful at a level of -60db level due to digital artefacts.

Wow... never ? I'm shocked tbh. Mind you, special is good... particularly audio bargains at supermarkets 😀 You might be surprised just how good. There's some Well good Technology on offer.

There you go... another cryptic clue for you all 😀

Hmm 75dB SNR, that is very bad indeed.

But I haven't moved to computer based music server so that's all I have to play your test files. Of course I know how bad they sounded but as I have said, I can burn the files to cd and play them thru my normal music system if I had the need to.
 
Rhythm and soul indeed!

Finally dug out (divorce move! :flame:) my better USB DAC (iFi-audio iDAC) with headphone out and the tap on the cymbal and brass sounds a bit more 'biting' at times, not sure???

Yay, another listener 😀 Thanks for joining in. Listen to it again, more closely... do any of the sections I mentioned a few posts back sound more appealing than others. If it was a £$1000 of your money you were writing the cheque for, for a new audio component... which section would it be.
 
.... but everything is then A/D recorded by a soundcard, right?

Hmmm, I think the paragraph was a bit confusing. :scratch1:

...
Track 1 was a mix of direct rip to wav (so as good as it gets) which then switched randomly to playback via the Sony CDP790 with the 5 cheap electros in circuit to. This was then fed into an A/D convertor. A test track of -10 db was ripped directly and also played and recorded from the Sony to set absolute levels.

A picture will show all...



The top track is the direct rip and the lower the Sony CDP790 +caps.
...

I think it was just track 2 that was ADed, track 1 was direct rip to .wav, no AD and then the final track was composed by switching back and forth.

Is that right Mooly?

Yes, the top two traces are L and R of the direct rip of the CD and the lower two are the L and R of the file created by feeding the line out of the Sony player via caps and into the A/D input of the PC. Levels were matched on a scope using a Philips test disc and -10db track. The two tracks were aligned as best I could and then parts of each were cut as seen in the picture. Get the cuts to occur at the same point on each and the result should be a noise free join.

I built my own gears since very long time ago, even cd transport.

For speakers, I can listen in blind and have sufficient knowledge about what I hear, the mistake and the potential.

For electronics, I need to know only the schematic plus standard spec. If I don't have access to schematic, I need to listen the electronics with the speaker I know, of course reference speaker.

As for listening to judge, I'll be very happy to pay $1000 for one product among several products in the price range of $500 to $1500 by listening blind 😀
 
Ah I see, now I know what we're doing I could actually pay more attention. When listening before I was under the effect of a mild sedative with a heater on just listening for anything that might sound unpleasant, rather than trying to pick out audible changes. Nevertheless, one could say, if something isn't immediately apparent, then the difference isn't big enough to care about.

I might try on the headphones too.

So what do you hear Jay. Which section of the track comes across as the best sounding to you. And "best" as in you prefer that sound over the other sections.

Thats how I do most of these tests. A pair of ancient Sony MDR -V7's
