John Curl's Blowtorch preamplifier part II

I guess I would just put Gehry at the bottom of the list, his designs seem so senseless.

I reckon Gaudi will also end up on the bottom of your list.

Any fallen Wall Street guy, I'd advise to go out in style and pick the only scyscraper worth the view, Gehry's Beekman tower in Brooklyn.

(with sufficient candidates, they might rename the adress to 21 Jump street)

Amusing bit about Mr Gehry's design in Cambridge is that MIT didn't realise from the start that they would undoubtedly have to sue the architect.

This is probably too easy to cheat on, the spectral artifacts of MP3 at any bit rate are usually obvious on the live FFT that some players have. My default player is Cooledit with the FFT window open.

Fair enough :) Perhaps I should just say 'well don't look at the screen then' :D

And anyone else... have a go... have a listen. As with all these kind of tests, its like pulling teeth to get folk to just listen. If we are not honest with ourselves in what we hear then there is no real hope in all this.

Gaudi's place is great art. Especially dramatic when seen from the distance with contrasting plain rectangle buildings of the neighborhood all around it. And, just as interesting inside as outside. But not really all that large..... but they are still working to complete his plans. Now, the 27 story family home in Mumbai.... that is BIG and major Ugly.

So what happens if someone gets it wrong?

Nothing :) No ones going to come knocking on your door.

And wrong in what way ? If (if !) there is a detectable audible difference then some might actually prefer the MP3 over the uncompressed. To give you all an idea, the WAV is around 26mb vs just 4.76mb for the 'better or higher bitrate' of the two MP3's.

If someone was actually honest in listening and perhaps said 'look, I can't really tell for certain, I'm not sure. I'd be happy with either and perhaps went on to say... but they both sound way better through that amp than this one' then, maybe then we can start getting somewhere and seeing where audible differences really are.

Just enlighten me :)

If you had a selection of MP3's of the same track (but encoded back to WAV as in these files) and all at differing bit rates of say 320, 256 and 192kbs, could you put them in order via FFT analysis (or other means at your disposal) or would they just show as probably MP3.
 
Jacco,
At least with that architect I can tell that it is a building that people are inside of. With the Gehry building here in LA if you didn't know what it was you would have no clue what you were looking at, just crazy surfaces with no clue why it is there. I guess I am just getting old and tired of seeing things that are different just to be different.

Can you tell between them?
 
Though we dont need more than 24 bits for playback..... with DAWorkstations, if they dont have 32 or more bits, internal clipping et al results with excessive mixing, combining tracks etc. The cheap-o gear for home recording just cannot ever do a clean job of it with inadequate bits etc.

All the audio related software I have uses double precision floating point math (64bit).

Simple misspelling has gone to mistaken identity Gehry is not Gaudi (unless you meant the Gaudi cathedral??) I love both BTW, my wife and I would like to rent a Gaudi place in Barcelona for a while. The idiot tour guides still say gaudy comes from Gaudi, I guess they don't teach Latin anymore.

I would think ProTools or one of the free software audio solutions should handle the mixing and editing but by then you surely should have a clean source to begin with. If your using a $20.00 dynamic mic and a noisy mix console intended for cheap consumer PA gear I don't think your ever going to get a great let alone good recording. It is going to start at the mic and go from there, there is no substitute for quality audio gear in the recording chain.

I have just listened via my main set up (speakers) for the first time with these. I can't switch between the two instantly (like using foobar) as I loaded the tracks onto a flash drive plugged straight into the frony USB socket of my Marantz Pearl Lite.

So that's set up #1

Honest impressions. I played each twice through at highish level and also kept jumping to the start of one and then the other.

And I'm not sure :) I have the advantage of knowing which is which and I sometimes think I prefer the one I shouldn't. Each in isolation is excellent and I would be happy to use either to evaluate other components in the chain.

What I going to do now is play them with Foobar and use my Sony MDR-V7 headphones. I'm not going to keep running and re-running Foobar. I'll do one run of 10 and post the result.

I was referring to A.Gaudi C. in Barcelona, of course. His home, in particualr... I was inside it.... dont know if they allow that anymore. The cathedral is very close by. it IS pretty guady, too. But, I like wack-o stuff.

As promised. First and only run with Foobar on the Liszt piece (X and Y).

Be careful of hearing fatigue. A is a mp3.
