Well, I have just spent the last 2 hours trying to repeat this scenario and failed miserably. The only difference is my previous test was using a spare pc running XP and my current test was with Win7 though I doubt this is the root cause. Time permitting I will put my audio card in the XP m/c and re-test. Sorry I cannot be of more help especially as I have seen this before.Been there done that myself
My error was not having consistency throughout.
Transferring my LP's but Audacity slo-mo's the music!

Re: Transferring my LP's but Audacity slo-mo's the music!
*** A SOLUTION ***
I was having the same issue with playback speed being off, but my recorded audio was playing back at faster speed, changing the pitch by more than a half step, i think.
I am using Win XP 32 bit
Audacity 2.0.1
Lexicon Alpha USB recording studio (Input/Output device)
Sigmatel Audio (CPU's built in sound card)
LMMS for creating and exporting loops as .wav files, then importing into Audacity
MME driver (Portaudio?) instead of Windows Direct which seems to get really crackly when monitoring backing tracks during recording
Those who have thought the issue is with Project Rate (Hz) settings and sound card issues are on the right track i think. dig that pun.
While recording through the USB input/output my guitar sounded in tune with previously created loops, however on playback the recorded audio had sped up, causing a change in pitch. The solution seems to be the combo of bit rate and Project Rate settings.
I was using default export settings from LMMS at 41000Hz and 16bit for creating .WAV files.
Setting the respective project and bit rate to the same values in Audacity did not solve the problem.
*** Here's what is working for me: ****
Using MME as the "Host" Interface.
Exporting from LMMS at 48000Hz, 16 bit "Depth" instead of 32 bit float, and left all other default settings alone.
Matching Audacity's "Default Sample Rate" to 48000Hz, and "Default Sample Format" to 16 bit in: Preferences > Quality. This switched the project rate as well.
No more time/pitch change! I think the fact that some people are having slower recorded speeds and others faster suggests this is definitely just trial and error fine tuning the settings depending on soundcard. Audacity's auto detect feature may not be interfacing correctly with all soundcards, or maybe just really old ones like I've got. I'm no programmer.
May not be the best recording quality but this will do the job as I need it. Sounds pretty damn good actually. Not bad for free software, with Win XP on an 8 year old laptop. Hope this helps someone else...
Good luck, & thanks to Audacity team.
