This unfortunately requires a lot more processing power, but provides perfect sound in nearly all games.
However, some issues may remain, and all sound issues need to be confirmed with LLE. Currently DSP HLE will have perfect sound in most games.
4.0-7286 and New-Zelda-HLE rewrote the Zelda ucode, improving it for the remaining games. 3.5-78 and 3.5-1154 corrected most of the problems in the AX ucode, the most common audio microcode on the GameCube and Wii. DSP HLE is with almost no overhead and does not require any additional files, however it may have some problems in some games. The DSP is an additional processor used by the Wii/GCN to process sound.
