For anybody hunting down this specific translation in audio format, Audible is the most straightforward place. I borrowed the library edition from Libby first, but it was the Constance Garnett translation, which felt a bit more dated to my ear. So I ended up using a credit on Audible for the Pevear and Volokhonsky version narrated by George Guidall. Guidall's delivery captures that grinding, interior anxiety of Raskolnikov perfectly—it's exactly the tone I wanted.
You might also spot it on Audiobooks.com or Google Play Audiobooks, but pricing fluctuates. I'd check if your local library's digital service has it, but in my experience, the newer, acclaimed translations like this one are less common in those collections than the public domain versions. Still worth a quick search before spending, though.
