An aside on DIY encoding where we do have a choice.

When ripping vinyl records I use 48kHz or higher sample rate, rather than the 44k1 used on CD's. It will only be as good as the analogue signal that goes into the ADC.

I still plan to convert my vinyl files to 96Khz and 24 bit. These will be the archive quality files. I will then carry out corrections (click-repair for example) on these files before downsampling to say 44KHz 16bit.

My logic is that in photography it is regarded as'best practice' to carry out photo corrections on the raw files. The raw files are unaltered and the corrections are stored as a set of instructions. Files can then be converted to 16bit Tif or 8 bit jpeg files for printing.

I use Vinyl Studio for vinyl capture and one great advantage of that software is that when any modifications are made, the original sample is unaltered and changes as stored as a set of instructions. Final conversion is only made when saving to final output as flac etc.

It seems to me that in the treatment of vinyl conversion, there may be a good comparison with digital photographic files.

Whether I'm right or wrong, I would hate to complete 12 months of vinyl correction onyl to find that I had to repeat the process at a higher resolution.

Hi Marsh, I use Vinyl Studio and like the way the raw file and edit trail are separated. The album/track info lookup is very helpful too!

Perhaps we had best get back on topic. I have run a couple of my v-rips through Sonic Visualiser and there's plenty of treble. Unfixed clicks are quite visible.
