How Do I Convert Cubase AI Audio Mixdowns Into MP3 Files on Windows Computers?
1) There is an optional MP3 encoder that will run inside Cubase available here; http://www.steinberg.net/en/shop/buy_product/sku/500242444.html
This will expand your export selection to include MP3 file types.
2) You can also import the mixdown into ITUNES as a MP3.
3) In ITUNES, click on edit , then click on preferences and on the “General” tab.
4) Click on import settings and select how files are going to import and at what MP3 resolution.
