Atlus is reportedly in the process of delivering a post-launch patch for the recently released remaster of Persona 3 Portable on PS4 and other platforms. The update will, according to SMT Network, address issues with the port's audio quality.
We reviewed the Persona 3 Portable just last week, and we did note that the remaster has some audio balance issues. Indeed, some voice lines and sound effects can seem incredibly compressed or overly loud. It's not something that distracts from the game's overall appeal, but it is noticeable at points.
