Not really sure how to handle this. Maybe when 4.0 comes out, I'll rework this to just say that HLE is really good now.
(Update regarding the new included DSP ROM files. I have no idea how we're going to differentiate them in wiki pages >_<. We'll see when an error pops up.) |

The DSP is an additional processor used by the Wii/GCN to process sound. Dolphin has two ways to emulate the DSP. | The DSP is an additional processor used by the Wii/GCN to process sound. Dolphin has two ways to emulate the DSP. | ||
*HLE (High Level Emulation): HLE works by using a DSP engine created by the developers from studying the real DSP. It is not perfect, and is notorious for causing garbled sounds, choppy audio, skipped instrumentation, and desyncs. But DSP HLE is very fast | *HLE (High Level Emulation): HLE works by using a DSP engine created by the developers from studying the real DSP. It is not perfect, and is notorious for causing garbled sounds, choppy audio, skipped instrumentation, and desyncs.

**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. As of 3.5-1154 DSP HLE is very good. | |||
*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. It's 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.
