There is probably an easier and more professional way to do what I did (Using audacity or Adobe Audition) but I am more familiar with Premier Pro.

1) Imported film into PP, watched film found funny quotes, put them in seperate sequence then exported them.

2) Whatever you use, export them as MP3 and use a low encoding speed 128kbp/s and below. Keep taunts preferably short with seconds of grace at the start and end if allowed.

Note: make sure you place a number in front of the exported MP3. This will be used to tell which taunt to play in chat window.

3) Drop them into your AoE2 game folder (after testing them) It can be found in Steam--> Steam Apps-->Common-Aoe2-->Taunts.

4) Open AoE2, go to map editor, then Steam Workshop. Direct it to the files in the taunts, put in all the relevant details then publish.

Thank you GrooveFactor :) I couldn't find the steam folder on my computer, until I discovered there was a second program files folder called Program files (x86). Why are there two program files folders?

I have Pro Tools and FL Studio. Could those softwares help in creating taunts?
