I would guess to save on installed size?

It's not about size or file count or disk space consumed. The question is about why would you require the extra overhead of playing the compressed version which involves decompressing it on the fly in some way, versus just playing the already decompressed version.

In this case it was stated that both the compressed and decompressed versions live side by side. So there is no install size saved.

The OP stated

"The game Titanfall on PC has the audio in it twice, compressed and decompressed."

'has it twice' could just be on the install media, and compressed/ uncompressed chosen as a trade off between install size and performance.

Anyway searching around the OP seems to be misrembering. Titanfall seems to be well-known for 35gb out of the 48gb install being uncompressed audio. I couldn't find a reference to it also having compressed audio also.
