Re: low latency linux audio i/o library

AFAIR PulseAudio is not about the real-time performance and low latency.
If you want to write low-latency program, consider using JACK or ALSA.

Re: LSP Project

I'm a bit confused which branch to install now of the LSP plugins. Guess the recent bug fixes are not implemented in the master yet? I also wanted to setup the parametric EQ, but I don't see any APO option in the mode. Maybe I'm missing the recent changes, because last time installed from the spect...

Re: LSP Project

Great :) Thanks! The list of affected plugins by this bug: Parametric Equalizer, Graphic Equalizer, Spectrum Analyzer, Multiband Compressor. Merged changes to devel branch. Removed spectrum-analyzer branch. Added patch to the hotfix branch which can be used as a patch source to the 1.1.10 release s...

I've reproduced the bug using your samples/buffer settings. The latest patch should fix the problem.

Re: LSP Project

I'm using 1056 samples @ 48 kHz and 3 periods/buffer. 1056? It's non-standard power-of-two buffer size. Maybe it's related to such settings. Anyway, please try this commit: https://github.com/sadko4u/lsp-plugins/commit/d24b14f48618bd3add027d8b1c16282edc7f4c25 It seems that there was a really buffer...

Re: LSP Project

Still crashing: I see still count being too huge: count=18446744073703159930 Have you properly rebuilt plugins? You need to issue: make clean before you'll start any build. Also, what's your audio settings - Sample rate, buffer size, etc? Maybe I'll try to launch plugins with your settings. Edit: A...

Re: LSP Project

I've noticed that LSP does not require downloading the proprietary VST2 SDK by Steinberg like most libre VST plugins I know, and all the VST-related files (such as those in include/container/vst or include/3rdparty/steinberg) are authored by you. How does that work exactly? If your code allows writ...

Re: LSP Project

I assumed something with the graphic as the desktop completely freezed, but I don't have any clue :) I've created spectrum-analyzer branch and pushed commit: https://github.com/sadko4u/lsp-plugins/commit/926c0ddf33efc4d70ef328f99bae19509809a7d6 Please try to reproduce the problem with this branch.

Hmm, seems that sse::copy is called with invalid count argument value (which is too large): Thread 28 (Thread 0x7fffbc507700 (LWP 12677)): #0 0x00007fff8616a08f in sse::copy (dst=0xe6c9200, src=0xe6ca218, count=18446744073703159930) at /home/marco/src/lsp_plugins/lsp-plugins/include/dsp/arch/x86/sse...

Now. ..finally (I killed compton before doing the test) edit: Stupid question, but if I delete the folder /home/marco/src/lsp_plugins/ it will not work anymore, as these files (source code) are still needed for the back trace, right? No, backtrace is a part of debug information which is a part of c...

If Ardour freezed, then that's good, too. If you execute it with --gdb option, you can Ctrl-C the process and watch thread states with:

If you've built all plugins and installed them, you just can simply execute from console:

Code: Select all

lsp-plugins-spectrum-analyzer-x12

For proper work, you need to JACK been started first.

Re: LSP Project

There's nothing special, just usual work in logs.
Is the problem reproducible for standalone version of plugins?
AFAIR, you've reproduced the problem with Ardour. Could you run ardour with option --gdb, wait until it crashes and output the stack trace?

Re: HOWTO: Quick Frequency Response Measurements Using JAPA and Faust

Thanks! I thought it's not implemented yet. Wow... the difference between e.g. APO and RLC is quite huge. Is it because of different Q definitions? This is also because of a bit different filter design: APO - Digital biquad filters derived from canonic analog biquad prototypes digitalized through B...
