Lancer
Lancer is the codename for the highly-optimized Vorbis libraries and utilities by BlackSword of the Ogg Vorbis Acceleration Project.
The latest version, Lancer 20060506 (20060512 for MT versions), is based on aoTuV beta 4.51. It includes the accelerated versions of:
- oggenc2.83
- OggDropXPd 1.8.9
- Vorbis dynamic link libraries (ogg.dll, vorbis.dll, vorbisenc.dll, vorbisfile.dll)
- libvorbis.dll
Note that starting version 20060506, BlackSword now provides several versions of the Lancer suite, each optimized for a certain processor feature. Here's a quick run-down (not exhaustive!) of the versions:
- 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 version should run faster on Hyper-Threading capable processors or Multiprocessor systems.
Newer processors should support SSE3. However you should confirm this with the processor manufacturer. Or, you can also test whether a certain SSE level is supported by your processor: Simply download and run OggEnc2.83 for the SSE level you are testing for. If your processor does not support it, OggEnc2.83 will tell you so and exit gracefully.
