Audacity Forum

Sorry, there were 3 questions;

1) Immediately before exporting, look in the bottom left corner of the Audacity window - what does it say for "Project Rate"?
2) On the left end of the audio track it will say something like "stereo 44100Hz 32-bit float". What does yours say?
3) In "Edit menu > Preferences > Quality" what settings do you have?

Project rate: 44100
On the left of the audio tracks: some are stereo 44100Hz 32-bit float and some are mono stereo 44100Hz 32-bit float (I can split them if needed, just was messing around with effects and things)

and quality settings: 44100 Hz 32 bit float

What exactly is the audio that you are exporting to produce these strange silent MP3 files?
What happens if you export as WAV

I tried to export as WAV 3 times:
1st time: the first half worked, the half way through just went blank
2nd: blank
3rd: blank

What exactly is the audio that you are exporting to produce these strange silent MP3 files?
The only way I can reproduce these symptoms are by creating corrupt data in the audio track.

thanks for helping but i've given up now. I've still got 3/4 exported anyway so yeah, thanks
