So you ABXed the two mp3s then?

Yes.

So if you are able to differentiate between them using ABX, what do you deduce from that?

That the MP3 I converted myself sounds different to the MP3 that was downloaded from Linn.

 

But I couldn't tell the difference in an ABX test between the MP3 I converted myself and the Linn FLAC file. These two sound identical.

So what do you deduce from *that*?

That the Linn MP3 has been mastered to sound different to the FLAC version.

Which is at odds with what they've said, right?

What Linn are saying doesn't make much sense.

See post #12 on page 16.

RE: Better mastered music could be on the way!

Here's todays free track 'Sunbeam Melts The Hour' by RM Hubbert.

I think that these three pictures can speak for themselves.

 

Linn downloaded MP3

Linn downloaded FLAC

My MP3 converted from the original Linn FLAC file

RE: Better mastered music could be on the way!

If anyone reading this thread wants to check out my finding for themselves you can download and install Audacity from here: Clicky

 

You can download todays FLAC and MP3 files from Linn from here: Clicky

 

Then all that you need to do is open the MP3 and FLAC files in Audacity and see what they look and sound like for yourselves.

Actually, it did make sense, if you believe that mp3 encoders can produce different results.  If you don't, or don't think that they can produce results as different as you see, that must bring us back to BenLaw's question to you:

In the context of Steve's findings, I don't think it did make sense. Sure, a file may be different depending which mp3 decoder is used, but none should change the volume, change the dynamic range or delete the beginning and end. Hence my question / conclusion (not specifically aimed at Steve, although he's welcome to answer). Hard to say which of the options, although the ignorance / incompetence would be fairly staggering.

Strange line of questioning JD, what do you deduce from Steves findings?  I can think of a third option, maybe Linn don't care as much about the quality of the mp3.  They could always ask Steve which mp3 encoder he is using that seems to be consistently better than theirs.

RE: Better mastered music could be on the way!

I don't think what Linn says makes sense.

Audio compression (reduction of audio dynamic range) is a completely different situation, and effect, to digital compression (used to reduce file sizes).

FLAC and MP3 are digital file compression techniques, not audio dynamic range of loudness compression techniques.

Linn's explanation does not believably satisfy steve_1979's enquiry.

His conversions to MP3 clearly illustrate that.

RE: Better mastered music could be on the way!

If the quality hasn't suffered (and TBF Steve has emphasized this), and Linn's 320 kbps is up with the best of them, everything else is surely academic.

RE: Better mastered music could be on the way!

To answer an earlier question about what we can deduce from Steves findings, I'd guess that the mp3s were made or taken from different sources than the high resolution samples. If not then the mp3s were created from the high res recordings and the files then amended.

Unless the mp3 encoders used, arbitrarily effect dynamic range, volume and track length.

What about you JD? What do you think?

But he has said that some tracks sound different.

I think they were the Non-Linn Record ones......which they can't alter.

(I'm too tired to trawl back, to find out for sure)
