**DSP HLE is improving on a regular basis, and versions {{revision|3.5-78}} introduced fixes for many GameCube games' HLE audio, and {{revision|3.5-1154}} brought those same improvements to Wii games and refined them further.

*LLE (Low Level Emulation): LLE uses DSP ROM files to emulate the DSP's hardware behavior. This unfortunately requires a lot more processing power, but provides perfect sound in nearly all games. As of {{revision|3.5-1031}} Dolphin includes a developer-created DSP ROM which allows DSP LLE to function without dumping LLE files from a console. Its compatibility is very good, but it will have errors that a DSP ROM from a console does not have. | *LLE (Low Level Emulation): LLE uses DSP ROM files to emulate the DSP's hardware behavior.

For the absolute best audio, DSP ROM files should be dumped from a console. There are several ways to dump DSP files, but the easiest method is to use DSPSpy on a Wii with the Homebrew Channel installed. For details on other methods to dump DSP files, go to the {{forum|forum thread|tid=23103}}. | For the absolute best audio, DSP ROM files should be dumped from a console.

== | == Dumping Wii DSP files from the homebrewed Wii == | ||
Requires an homebrewed Wii. See how to install [http://wiibrew.org/wiki/Homebrew_Channel Homebrew Channel] on non-hacked Wii console. A SD card is also required for this procedure. Continue if you have met with every requirements. | |||
Download DSPSpy and extract the files. Then, rename "DSPSpy_wii_dump_roms.dol" to "boot.dol" and place the files into a folder in your apps folder on your SD card (example: E:/apps/DSPSpy). | Download [http://forums.dolphin-emu.org/attachment.php?aid=7636 DSPSpy] and extract the files. Then, rename "DSPSpy_wii_dump_roms.dol" to "boot.dol" and place the files into a folder in your apps folder on your SD card (example: E:/apps/DSPSpy). Launch the app from Homebrew Channel on your Wii, and two files will be created: "dsp_rom.bin" (8KiB) and "dsp_coef.bin"(4KiB). Move these files into your [[Controlling the Global User Directory|Global User Directory]] "GC" folder, which by default on Windows is located in C:\Users\[your username]\Documents\Dolphin Emulator, and Dolphin will now have official DSP ROMs from your Wii. | ||
