After editing a one-hour podcast, I add the intro and outro music. At this point, playback becomes unusable, as it is accompanied by deafening static. This buzz does not get exported, so I can still export the final MP3 that listeners will hear, but it makes it difficult to QA the final cut while in Audacity.
I recorded my latest experience with this issue here:
You actually reported the issue before and it was one of your projects you kindly posted that helped us find the playback problem.
Can you please double-check in 2.1.0-alpha that the exported files are OK? In your previous project you managed to save the distortion in the exported file so that it could be heard even on Windows (and still can, even in 2.1.0-alpha builds). It’s not clear that we have fixed any problem there may be in rendering data to disk, so please check.
