Hi,manicm said:So you're assuming then, according to your logic, where it doesn't really back up your claim. One of the Linn posters provided the white paper, where MQA actually applies dithering to the encoding process. So you're still guessing...shadders said:Hi,manicm said:Shadders, no I don't, but I suspecting you're twisting the piece to suit your belief. I ask you again to extract a piece or two from the absolutesound piece to back up your claim, or at least the page - there are only 4 pages.
That can't be too hard, can it?
Page 3 states that the temporal blur is the issue, and that this is caused by filters, where they reference 8 filters in the entire audio chain. For an existing album, they need to reverse this effect, hence they cannot record the album again, they will have to know which filters have been used so as to reverse the smearing effect.
'MQA addresses this disparity by losslessly (or virtually) dividing the audio into octave-wide sub-bands, conceptually coding each with a lower sampling rate than the ensemble. MQA is truly hierarchical, and although the example here is 192kHz, sample rates of 384, 768, or higher are accommodated. In fact, the mathematics includes infinite sampling (analog) since that is the real target.'
I've read page 3 again, and it still doesn't back up your claim. They may be removing that blur, but the HOW doesn't equate to any form of 'reversal', or reverse engineering of the audio in the strictest sense.
Not assuming. I asked you whether you understood DSP etc., to determine how I should respond. The only way to remove temporal blur by the stated 8 filters is to code an inverse function, which will in essence be an approximation.
You keep on referring to Linn, which I have not seen in regards to this aspect.
Your have copied the coding aspect. There are in essence two aspects to this - the processing of the existing recording, and the coding of the resultant bitstream. I am referring to the processing of the existing recording.
Please provide the link to the referenced white paper. Thanks.
