Dear Abbey

I have about a dozen voice/acoustic guitar mixes from the seventies - studio recorded. Managed to
get them onto my computer - tape is still good.
I must have been excited when I recorded them because now they seem maybe 5% too fast
to me. I'd like to slow them down by no more than 5% if that much. I have used a timeshifter
provided in the 'wave editor' of my Nero Burning software. I am told that there are artifacts in the slower version created in Nero (my dead ears can't detect this).
I know Audacity has a time shifter - I'm assuming some are better than others and leave fewer artifacts.
What is the Forum's collective experience and do you folks have any suggestions for a good time shifter???
