I have an Audacity project with three tracks all of the same event. One was recorded in Audacity at 44.1KHz (I meant to do 48KHz but that doesn't really matter). The other two were extracted from DV video tapes, and as such are at 32KHz. I'm trying to export the whole thing as separate tracks at 48KHz for use in a DVD, but it says it'll take 10 hours to export the first (44.1KHz) track.
I'm trying a workaround now where I export each track in its own native frequency and do the resampling to 48KHz later, and that seems to be going much faster. Why is exporting audio with mixed up sample rates like this so slow? Is there a way I could speed it up?

Re: Insanely Slow Export with Multiple Sample Rates
You haven't really given enough information. What distribution of Linux are you using? What version of Audacity (see Help > About Audacity) and is this a packaged version provided by your distribution or are you compiling Audacity from one of our release tarballs? Also at Help > About Audacity, click the "Build Information" tab. Under "Core Libraries", is libresample or libsamplerate being used for sample rate conversion?
