Azimer HLE/LLE Audio

Azimer’s HLE and LLE audio plugins are among the most developed N64 audio plugins available.

They are the most popular alternative to Jabo’s DirectSound plugin, thanks to a strong HLE sound engine that plays back the audio of almost every game accurately, with few slowdowns or glitches. Shunyuan’s audio plugin is its main competitor.

Development has been slow for many years, as Azimer has had little time to work on the plugins, and a 2013 release brought no further improvements to HLE sound emulation.

The plugin can run in either HLE or LLE mode: if the RSP plugin tells it to, it uses LLE, otherwise it stays in HLE mode.

Project64 Audio, the default audio plugin in current versions of Project64, is Project64’s own fork of Azimer’s plugin, so most Project64 users are already hearing an updated version of it.
