How to use macro to cut off last 3 seconds of audio files of many different lengths

[chefralsei]

I’m new to Audacity and I’m trying to make a macro to cut the last three seconds of audio clips of various lengths.

This is what I have:

1. Select All
2. Select Time (??? Unsure of how to get it to select everything BUT the last three seconds)
3. Trim Audio
4. Select All
5. Export as MP3
6. END

Any help would be much appreciated. Thanks so much!! : )
