Hi All,

I wonder if you can help.
I have recently registered with HA but have been reading the forums for months.
Very interesting and informative.

Being a recovering so called 'audiophile (fool)' I think I have at last found some sense in the real world!
But thats a whole other story for a different thread!

I have a collection of some 2000 LPs that I want to archive to digital.
Now I release that the topics of 44/16 v 96/24 has been widely discussed but just to be clear and please
correct me if Im wrong on any of these points;

- Set the phono amp output to produce a max peak volume just below ADC clipping to maximise ADC coverage?

- 16 bits is more than enough, 24 bits does not produce a more detailed rip?

- Would 24 bits needed if I want to use declicking functions and rumble filters?

- If I always set the ADC input correctly normalisation should not be necessary?

- If tracks do need normalising to say -3db what does 24 bit over 16 bit prodivde?

- The noise floor is not lower with 24 v 16 bits, I dont think I understand the concept properly yet?

- 96K rather than 44K is worth doing for capture as it pushes any anti aliasing well out of the audio band.?

- There is no point in having a final cleaned corrected file greater than 44/16 as there is no audio benefit?

(BTW Im using a great software package called Vinyl Studio!)

Thanks for any comments,
Matthew

16/44.1 is more than good enough, and has maximum compatibility.

On rare occasions, wear-free LPs played on great set-ups can deliver greater (all-be-it inaudible) frequency response than 44.1kHz can sample (i.e. there's real content above 22kHz). Far more commonly, information from LP playback that's above 22kHz is pure distortion, but occasionally it's something real. For those of us who might want to pull out the digital copy to check the provenance of a given recording, sampling at 96kHz might be useful to preserve this information. It's also conceivable that some future audio restoration technique might benefit from capturing at the higher sample rate. It's also just conceivable that a large proportion of audio reproduction decades into the future will use higher sample rates, and one day, probably after we're all dead, upsampling from 44.1kHz will be more of a pain than having native 24/96 or DSD or whatever.

Of all the decisions you'll have to make regarding LP transfer, sample rate is by far the least important, because 44.1kHz more than good enough (I said that already, didn't I?) and anything better can always be down-converted to 44.1kHz for use on CDs, players than only support 44.1kHz, etc. Whereas many many other factors have an audible impact on the results. e.g. condition of LP, choice of turntable, and (potentially) bad decisions regarding denoising + EQ.

Sanity hints: use FLAC for storage, add correct metadata (tags) ASAP, and ReplayGain album mode for levels.

Unless you're at home all day with nothing else to do, 2000 LPs will take you years. Start with a couple you don't really care about to test your process on, and then start again with the ones you're most likely to listen to, working downwards in preference. Then if you never finish, at least you'll have the most important ones copied.

Cheers,
David.
