compress narrations for export to PowerPoint 2011 on iMac

I’m new to Audacity and need to compress narrations that I export into PowerPoint 2011 slides produced using El Capitan (iMac). Currently doing this as 16-bit .WAV – but files are too large to email them in my PPT presentation. Any suggestions for compressing narrations made with Audacity 2.1.2?

Look at the help for your version of Powerpoint to find out what compressed audio formats it supports.

If it supports MP3, export as that. You will need to add LAME to your computer: http://manual.audacityteam.org/man/faq_installation_and_plug_ins.html#maclame.
