I love Audacity and don’t know what I’d do without it, but am now having a tiff with it. I have recently downloaded some mp3 audio lectures that I attempted to listen to while commuting in the car. Unfortunately they’re too quiet and can’t quite be heard above the ambient noise of an auto on the freeway. I wanted to use Audacity to chain an amplitude increase (my multimedia workstation is getting a bit old so yes, on this version of Audacity it’s a “chain” rather than a macro–but I like the old version better anyway).
The problem is that peaks are different in each file. In some files the maximum amplification before clipping goes up to 1.5; in others it dips down to about .8 and therefore each file needs to be amplified separately on a case-by-case basis, so a chain won’t work to do this. But I was hoping that at least I could avoid the tedium of sitting through 30 seconds to a minute of Export. These are long, ca. 40-minute files, and they take a long time to export. I wanted to make the amplitude changes in a bunch of Audacity project files and then use a chain just to apply Export on those projects, assuming that it would export the amplitude changes too. Then I could just walk away from the machine for a good 15 minutes while it took care of all that exporting.
Never having had occasion to batch Audacity projects before, I didn’t know you couldn’t–and, unhappily, now I do. This really sucks. Is there a way to do what I want, or am I stuck going through each d—d lecture and having to sit through the exports?
