0.4.3 30 days ago

This release includes several attempts to reduce cpu usage (from around 28% to 12% on Intel Celeron G1820 2.7G):
1. Wave data related computation is disabled when not required.
2. Buffer shader related computation is disabled when not required. It is only required by several effects, e.g., spectrogram and bar1ch (glowbar does not require it).
3. Default frequency range is set to 0-1800Hz.
4. Default fps is set to 30.

8 I think Panon is great eye candy for the desktop. Be aware that Panon spectrum analyzer doesn't appear to be working after KDE frameworks updates to 5.76. If you run the suggested qt5 sockets that Panon lists for KDE Framework 5.63, it will lock your Latte dock. There doesn't appear to be an issue way to unlock it, unless you have a Timeshift restore point prior to running the these packages. I look forward to installing panon again when it is compatible with KDE Frameworks 5.76.

You can try install the latest "master" branch. (v0.4.2 was built from the "stable" branch). I introduced qt-3d to replace ImageShader in the master branch, and it helps reduce cpu usage. I guess it also has the potential to solve your issue. But this qt-3d version has its own issue, that it can pollute the buffers of latte-dock/plasmashell. I don't know why it happened, and I thought it should not be allowed.

It is not working for me.
I tried using the most recent version, but since my kde-newstuff version is at 5.54 i changed to
the alternative one. It was showing a rainbow line for me, but not working.
With the alternative version it just shows an empty box. In panel looks like an spacer and in desktop just a black box.
Any help would be appreciated.

If you see a rainbow, then I guess the front end is working correctly. But the back end cannot catch any audio data. If you try to open an issue template in github's repo, you will see an instruction about how to get the back end logging messages. Any error shown in the logging messages can help.

Not sure if this is a new bug as I just tried this plasmoid, but I get "Error: Failed to load visual effect...". I have a couple visual effects located in '~/.local/share/panon` but I can't select anything in Panon Settings - Visual Effects, drop down does nothing. On Arch, all prerequisites installed.

Never saw this bug before. I need to know the outputs of the console. Github's issue template will tell you how to get the outputs. https://github.com/rbn42/panon/issues/new?assignees=&labels=bug&template=bug_report.md&title=%5BBUG%5D+%7Btitle%7D

Really like this, have a minor RFE - could you make it so that we could mix all of the speakers without also having to mix in the microphones?

I'd like to be able to set it so that it works whether my sound output is through my speakers or my headset, but without reacting to the background noise in my room

Done. I have pushed it to github.

I've just installed that (and thanks for the swift response) - I can see the option for mix all speakers, but it doesn't appear to work. If I select 'monitor source of ' as the input device, then it will react as expected (as long as that's my selected audio device), but the all speakers one doesn't appear to do anything.

I think it's most likely something a bit screwy in my PulseAudio settings, so i'll have a dig through that and see what I can find :)
