Open DCP Audio Glitch

I need to create a DCP file for a preshow on my digital projector at my drive in. The FAQ says the source files needed for audio to make a DCP are : “24-bit PCM 48khz or 96khz wav files (each channel is a separate mono wav file)” ( Im having trouble figuring out how to do this in Audacity.

Please Help!

I know nothing about DCP, but to export a “24-bit PCM 48khz” WAV file:

Set the project rate to 48000 (bottom left corner of the main Audacity window.
“File menu > Export” and select “other uncompressed files” as the file type", then click on the “options” button.
In the “options” select “WAV (Microsoft)” and “Signed 24 bit”.

Click “OK” then export in the usual way.
