Justin Ruggles	8821ae649e	lavr: fix handling of custom mix matrices Adds some validation for changing parameters after setting the matrix and fixes a bug in the conversion path setup.	12 years ago
Justin Ruggles	e9da9a3111	lavr: x86: improve non-SSE4 version of S16_TO_S32_SX macro Removes a false dependency on existing contents of the 2nd dst register, giving better performance for OOE.	12 years ago
Justin Ruggles	2f096bb10e	lavr: add x86-optimized mixing functions Adds optimized functions for mixing 3 through 8 input channels to 1 and 2 output channels in fltp or s16p format with flt coeffs.	12 years ago

Justin Ruggles	acd9948e74	lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes Changed to match the number of parameters in conv_func_interleave(), which is how they are called. The change isn't strictly necessary because the 4th parameter is not used, but the code is clearer if they match.	13 years ago

Justin Ruggles	5cc6d5244d	lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX The current SSE version is slower than the MMX version on Athlon64 and Sandy Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.	13 years ago
Anton Khirnov	9684341346	lavr: do not try to copy to uninitialized output audio data. This would happen at least when lavr is used as a fifo with no conversion.	13 years ago
