He did, however, admit that most PC gamers probably wouldn’t even notice the difference.

Key to Respawn’s ethos is pursuit of low-latency controls, the best possible ‘handshake’ between the player and the game, something that having compressed audio and having the CPU uncompress it on-the-fly, could possibly interfere with, Respawn lead engineer Richard Baker explained to Eurogamer. Respawn has now explained that the reason the audio was not compressed was so they could dedicate more system resources to running the game, and less to unpacking audio files. Some digging around in the files revealed that a huge portion of that size was due to a whopping 35 GB of completely uncompressed audio.

PC gamers (especially those with SSDs) were puzzled to find out that Titanfall had a gargantuan 48 GB file size, despite the lack of a single player campaign and the fact that it was running on a modified source engine. Respawn says Titanfall‘s gargantuan file size is so they can dedicate more system resources to running the game.
