In this thread the testers should post comparisons of the preset modes of Yalac (Working name for "Yet another lossless audio compressor") with other lossless compressors. The results for specific variations of individual encoder options should go into the thread " Yalac – Evaluation and optimization". Guidelines Please post the exact version number of the compressors. Compression ratio should be specified in percent of the uncompressed file size. Speed figures should be specified as multiple of real time (duration of the test files). A specification of your test system, especially the CPU, would be helpful. Open end: Feel free to add more results later. What happened Bad timing of my introduction (April 1.) forced an early publication of an evaluation release of Yalac, to prove, that it really works. This are results of 8 forum members, who where so kind to test the experimental release for me. Many thanks! Goals Yalac should finally achieve compression ratios on par with Monkey's Audio High. Decoding speed should be at least two times higher than Monkey and never be significantly lower than with FLAC (possibly Yalac will later be integrated into FLAC). My next steps The first results i have received from the testers show me some weaknesses of the encoder. That's a good thing, because that means, that there definitely is a chance to increase the compression efficiency! Same is true for the speed; especially the decoder is not fully optimized yet. But it will take some time, before i will come up with an optimized release. Links to 24 bit files i have used I think, they are hard to find.

You are really fast! But please don't post the whole protocol file. Most of the info isn't helpful yet. Summary of your results: CODE Run1: MMX + SSE Compression: 45.44 % Speed: 38.01 * real time Run 2: MMX Compression: 45.44 % Speed: 44.93 * real time Run 3: MMX + SSE Compression: 45.44 % Speed: 32.87 * real time You see the speed difference between Run 1 and Run 3, which use the same settings? And regarding Run 2: I advised to test SSE on Preset HIGH. You did use Preset FAST with 32 Predictors. But SSE will never be used with less than 64 Predictors! Hence all three test runs have used exactly the same optimizations: Always MMX, never SSE. The big speed variations are most probably beeing caused by variations of your test systems: Disk caching issues or disturbances by background activity. Under controled conditions all three runs should have achieved about the same speed (maybe within the range of +/- 10 %; on my system i achieve +/- 3 %). BTW: Activation of the protocol function slows encoding down. This post has been edited by TBeck: May 13 2006, 01:57 |

It seems my disk caching is quite unstable, then. I did hear thrashing sounds between the encoding of two songs. Also, run 1 is command-line; runs 2+3 are GUI.
I am currently testing Insane mode with/without SSE on my corpus (which compresses quite a bit, as you can see..) Results will be posted in approx 5 min. |

These results are actually quite surprising, as they show discrepancies in the SSE optimizations versus compression ratio. It should normally be the same, no?

It should normally be the same, no? I am quite new to SSE... I would have thought, that it gives the same results as single precision arithmetic performed by the floating point unit (FPU). Mabe it differs in the handling of rounding and underflows (i didn't care for the setting of the right SSE-Flags). But 0.01 percent deviation shouldn't be too important. But we should keep an eye on it (?). Far more interesting for me to see a significant speed benefit for SSE. At least big enough to try a bit more SSE optimizations later. Thanks Thomas P.S. Could you please post your CPU-type? Encoding speed for INSANE is more than two times higher than on my system. Surprising, because the speed of FAST isn't higher than on my system. FAST seems to be very sensitive to disk io performance. This post has been edited by TBeck: May 13 2006, 02:40 |
