Arun Raghavan	0b2457432a	volume: Get more data from volume tests ... This makes the volume tests run in two loops and print the minimum, maximum and standard deviation of readings from the inner loop. This makes it easier to reason out performance drops (i.e. algorithmic problems vs. other system issues such as processor contention).	2011-04-18 10:31:51 +02:00
Arun Raghavan	4cd90d9e32	volume: Add Orc-based optimised volume scaling ... This adds volume scaling for 1- and 2-channel software volume scaling using Orc. While testing the MMX and SSE backends on a Core2, I see an ~2x performance benefit over the hand-rolled MMX and SSE code. Since I haven't been able to test on other architectures, the Orc code is only used when MMX/SSE* is present. This can be changed in the future after testing on AMD and ARM machines.	2011-03-05 14:38:28 +05:30
