Lancer

Lancer is the codename for the highly-optimized Vorbis suite of libraries and utilities by BlackSword of the Ogg Vorbis Acceleration Project.

The latest version, Lancer 20060506 (20060512 for MT builds; see below), is based on aoTuV beta 4.51. It includes the accelerated versions of:

• Oggenc 2.83
• OggDropXPd 1.8.9
• Vorbis Dynamic Link Libraries (ogg.dll, vorbis.dll, vorbisenc.dll, vorbisfile.dll, libvorbis.dll)

Platform-specific Builds

Starting version 20060506, BlackSword provides several builds of the Lancer Suite. Each of these builds is optimized for a specific platform. Here's a quick run-down (not exhaustive!) of the builds:

• SSE: AthlonXP (Barton core and older), Pentium III
• SSE2: Athlon64, Opteron, Pentium IV
• SSE2MT: Multi-threading version of SSE2
• SSE3: Athlon64 Rev E (Venice & San Diego core), Pentium IV (Prescott core)
• SSE3MT: Multi-threading version of SSE3

Theoretically, the MT builds should run faster on Hyper-Threading capable processors or Multi-processor systems (including Multicore processors).

Newer processors should support SSE3. It is recommended that you confirm this with, either your processor manufacturer or someone familiar with your computer architecture. You have the ability to test, whether or not a certain SSE level is supported by your processor: Simply download and run Oggenc 2.83 for the SSE level that you plan on testing. If your processor does not support it, Oggenc 2.83 will tell you so and exit. Another way is to use freeware programs such as wcpuid and cpu-z.
