I sent a record of mine to an analog -> digital conversion service, and the CD that came back sounded like chipmunks. They had played the record at 45 RPM on their capturing equipment instead of the proper 33 1/3.
I was happy to discover that Audacity has a "change speed" filter with presets for vinyl RPM, so I can fix this on my own in software. It sounds okay on first listen, but I'm worried that this may cause a subtle degradation of quality.
Should I demand that the A->D service re-convert from the source vinyl? Or should I use some other tool (preferably one that runs on Linux) to get a better digital conversion?
