Clipping / Distortion when exporting

Hi
I am having problems to export my work to standard sound file (MP3 or WAV)
I always get a clipping on the output file, as if the volume before the conversion was too high, or before converting from float to fixed point.
no matter what I do it does not effect the output. I tried lowering the volume, mixing the desires channels, outputing to 32 float wav, or to MP3. I always get this clipping.
what am I doing wrong?
thanks

If you have a number of stacked tracks one above the other, it's not unusual for Audacity to play them OK in real time, but then add all the sound values on all the tracks and produced a destroyed Export.

Select all the tracks and apply Effect > Amplify filter to all of them (not just reduce the volume). I would start with -6dB if your show is heavily overloaded. If your output show volume becomes unstable, you can apply Chris's Compressor to the final WAV export to even everything out.

Not everybody supports 32-bit floating and that's Audacity's default. Audacity is a terrible standards converter, too, so I wouldn't fall in love with whipping in and out of different audio standards.
