Despite the photo above and the advertisement below, these records have been transferred using a modern lightweight pickup and the correct electronic equalization. (Though most of them will have been played on wind-up gramophones during their long life, the damage caused by the weight of the soundbox and arm, concentrated in a sharp steel needle, can be considerable and I would never allow any of them to be further worn this way.)
All the transfers are from originals in my collection. The condition is, as you would expect, variable - some came from proper collectors' shops, some from second hand and charity shops - many of these records have been kicking around for 80 years and it's a wonder they have survived as well as they have.
Filtering was kept to a minimum, in order not to reduce the high frequencies and take the life out of the recordings: then digital noise reduction was applied in two stages - de-crackle and de-hiss - using ClickRepair and DeNoise by Brian Davies. Again, care was taken not to overdo it: most commercial issues seem to aim for removing as much noise as they possibly can, and the results are usually rather dull-sounding compared with the originals. I aim to damage the original sound as little as possible, even though this may mean leaving a little more surface noise (and even so it's a vast improvement on the un-processed sound).
