I am currently working through some older gems in my collection. Some of these LPs have been attacked by mildew. Although I have thoroughly cleaned them, some of them still have surface noise. As a result, I have been spending several hours at a time on some of the older LPs de-noising them.
When I finish this pass of LP remastering, I shall be turning to remastering from pre-recorded tapes and some backups of LPs on tape that are in better condition than the LPs are now.
This remastering process is available on a small scale for gems that people may have. Contact me at graham@grahamshevlin.com for further details.
I am going to experiment in the next 2 weeks with remastering at 24 bit 96 Khz to DVD for several LPs, to see if the results are better than conventional CD mastering at 16 bits 44.1 Khz. The digital files will be recorded from the LP at 24 bit 96 KHz, not up-converted.
