i accidentally recorded a 7inch in 33 1/3 and wanted to ask if and how i need to set up audacity when i wanna turn the audio to 45 rpm?
With Effect → Change Speed you can directly enter the from/to RPMs.
Note that your RIAA equalization will be a little off, since the wrong frequencies were equalzed. But there error should be small, and given the low quality of most 45’s (assuming it’s an old record from the “vinyl days”) it’s probably not a big deal. And, a lot of older vinyl can benefit from a little EQ tweaking by ear anyway.
thx, found it !
