2011/12/12 v6.21 Added multicore support for Declipper and Loudness. Throughput is now 38% higher in presets that use both

2012/12/12 v7.00 Declipper: Improved splitting load over 2 cores
In CLI-version Stereo Tool can enable Multicore processing? (for Declipper)

On my CPU Core i7 (8 threads) is used only single core with an attached settings file (x.sts)

Sorry for not responding - I read your post and wanted to check it but forgot :(

It *should* work on multiple cores, unless the environment variable NUMBER_OF_PROCESSORS is set to 1 (or less). I'll run a test tomorrow to check what's happening. Anyway, the settings in the .sts file are ok (they should make it work on multiple cores).

I have by default: NUMBER_OF_PROCESSORS = 8 (Cores And Virtual Cores)

O wow. It would probably help if I remove the line:

common->MULTICORE = false;

from the command line version..... :)

Done, please wait for the next beta...

Ok, there was a reason why that line was there - with multicore on the command line version doesn't work. I know how to fix it but it will take some time.

Try the Windows version here:
viewtopic.php?f=14&t=4846&start=32

I realized this afternoon that there are 2 types of multi-threading in Stereo Tool:
- Inside filters. For example multiband or clipping is done in multiple threads.
- Some filters at the end of the chain are also multi-threaded. This has very little impact on the performance anymore.

The 'inside filters' multi-threading is now enabled for the command line version and Linux versions.

For "stereo_tool_cmd.exe" (v7.22) CPU usage = 12-13%

Good, then it uses 2 cores now.
