24 bit vinyl clips, Examples of 24 bit vinyl and bit-reduced versions Options

[Gretschguy]

Attached are several clips for vinyl rips, each in (24/48) and (16/44.1) -- I have many more but 7 I filled up my attachment space.

I used Izotope's SRC and MBit+ algorithms to do the conversion, I converted sample rate first and then bit rate.

The rips were done using Thorens Turntable, Lyra Delos cartride, Parasound phono pre, Burl B2 ADC, Lynx AES16 card, Pure Vinyl software.

If anyone has better conversion technology than Izotope I would be interested to hear those samples for my own comparison, as a practical matter I would like to have the best possible bit reduced versions in my library in addition to my 24 bit versions.

If anyone is interested in specific notes on what I'm hearing as the differences in my playback system then let me know.

The sources are:

Dire Straits "Romeo And Juliet"
Prefab Sprout "Faron Young"
Yes "Roundabout"
The National "Bloodbuzz Ohio"
Cat Stevens "Father And Son"
Roxy Music "Running Wild"
John Lennon "Mind Games"

Thanks for checking these out.

Thanks for the samples. A simple analysis showed that most don't even use over 20 dB dynamic range. There's one sample which uses ~31 dB dynamic range.

As for sample rate conversion I suggest SoX. Dithering shouldn't be audible with those dynamic range numbers unless you use some aggressive noise shaping that adds a lot of HF noise .. which is only audible if you don't have HF hearing loss though.

Thanks Xnor, I measured these on AudioLeak and I get about 20dB between peak to RMS. Typically my CDs measure less than that. So is your 20dB the same as what AudioLeak is measuring? Would it help if I gave the snapshot from AudioLeak?

The last I tested my HF response it was very good. I will check SOX and I'm also going to look at the frequency spectrum difference in the samples using Logic Pro's EQ match.
