Describe the bug
No pulseaudio devices and can only select "default" but it'll do nothing

FIX:
need the dependency python-cffi in the AUR package

or do pip install cffi

Just want to say thanks for your great work on this visualiser, I've been using it on my main desktop PC and it really spices up task bar. I'm not sure when you made these changes or if I uninstalled something but one day panon just stopped working and I've only recently gotten around to fixing it.

I think it can be implemented with help from aubio. There is a demo.

As it says, for some reason on every startup panon only reacts on input from laptop microphone, no matter which backend i choose (tested on all previous versions and also the this one), only sometimes randomly when i manually switch between input devices for microphone (internal / unplugged) and speaker (speakers / headphones) and restart panon in between it sometimes gets to ignore microphone and listen to regular sound output from laptop / headphones, but not really sure what affects its decision?

I saw there was similar issue posted but im not sure i really understand that whole situation in that post if its same, so to post it as well

Hello! I was wondering if we could get an opacity changer or a transparent setting?

I would rather not have the darkish box and make it transparent but I'm cool with it either way but it would be nice ^^

See my 2 pushes here. It should be the much faster and cleaner input for getting the current output but it doesn't work.

I'm not sure if it's just some super obvious bug but I'm pretty sure it's not my code but instead sound card being buggy.

Please see this comment from reddit (https://www.reddit.com/r/Python/comments/3k11g5/whats_a_good_sound_recording_library/cuu6gvy):

PyAudio is pretty clunky to use, I find. I would recommend sounddevice instead, which also interfaces with portaudio, but with a much nicer API and providing wheels (i.e. pip install sounddevice will work on Windows and OSX even though there are binary dependencies).

PyAudio is simply a wrapper for portaudio, sounddevice is a wrapper that tries to make portaudio pythonic. It provides a proper Stream class with play and record methods and callbacks for long-running interactive recordings. Additionally, there are some high level play and record standalone functions if all you need is play or record one short sample.

Finally, sounddevice uses CFFI, and is thus compatible with CPython and PyPy.

Full disclosure: I contributed to PyAudio back in the day (did the Py3 port), then built my own successor much like sounddevice, called PySoundCard, to which the creator of sounddevice contributed heavily. He then built sounddevice as a successor to PySoundCard since I didn't have enough time to develop it fast enough. I now heartily recommend you use sounddevice!

Perhaps sounddevice could solve some of the issues I'm having in issue #6

I like to have gravity east and use the widget vertically on my desktop. I resize it to be fairly narrow but on logout/log-back-in it resizes itself.

Describe the bug
Panon was working fine for a few days. Recently when I rebooted the system, the widget is showing: Failed to load the visual effect. Please choose another effect in the configuration file.

I do not see any input device in the back-end when I select PulseAudio. It only shows 01 device named "default". Also, I followed steps to remove NewStuff, restarted and nothing worked.

I love Panon and hoping the issue gets resolved soon.

sry for i poor english , i am learning english as second language

Should be super easy. Sadly the category isn’t available here, which I think is the reason it doesn’t work: https://store.kde.org/ocs/v1/content/categories

Searching for things in the category does work: https://api.kde-look.org/ocs/v1/content/data?categories=564&tags=panon

    configFile: Utils.get_root() + "/config/panon.knsrc"
}

@siyuandong @rvs75 can you help with the category problem?

hideTooltip: true currently result in a ugly little square being shown anyway.

That config should be removed and the tooltip improved to be useful (e.g. show the effect name or so)

I've tried to remove the old panon widget and completely reinstall the plugin, but to no avail sadly.
Some tests with PlasmoidViewer were unsuccessful as well:

Like already suggested in #19 would it be possible to change the default tooltip when hovering over the plasmoid to the current playing song and artist?

I think a similar implementation of this concept can be found here https://github.com/panagiotopoulos/MediaBar/blob/6855a61a59bd40ddabad8f801e61a2c73ff905a8/contents/ui/main.qml#L55

Describe the bug
When System wake from sleep panon switches Mix all speakers to Mix all Mic (Pulse audio)

When there are multiple output audio devices, for example, a headset on HDMI and a loudspeaker on built-in sound card. If you set the headset as the default output device, and then plug out the headset, panon will automatically switch to the loudspeaker, as well as other applications like mpd. But if you plug in the headset again, other applications like mpd will switch back to the headset, while panon will stick to the loudspeaker. You have to switch panon back to the headset manually in pavucontrol, or restart panon's back end by applying a small modification to FPS in configuration dialog.

I have no clue how to solve it.

Describe the bug

With variable latency devices such as my USB dac there is a bug with the rendering. When my USB DAC is not used it's latency is changed to the highest it can be. I presume this is to save CPU and power.

Problem is that when using this in "mixing all speakers" mode it causes the bar to stutter really really badly. I presume it's because the code is deadlocked while it's waiting for the buffer. Not sure if there is even a fix possible or just the nature of the Linux audio.

Anyhow I do think it's time this issue is addressed in a different manner. I propose a new separate "smart" single audio device setting. As most of the time users will only be using one device it should be the better alternative to mixing all for most users. The current mixing of all inputs is causing weird bugs like this.

In "smart" audio mode there is 2 processes. One is the current code. The second "watchdog" process is for monitoring which devices are currently in use and actually being played to. This can be achieved quite easily via some commands to see what is actually being played and to what sink/card. pacmd and other packages offer features like this, you probably know much more about this than I do.
Along with what devices are used it then checks the latencies and ensures it's below 1/FPS ms. In the case it's above the required latency show a warning triangle so users know something could be wrong or be user configurable to cut the stream completely to ensure a smooth FPS.
Other checks such as actually having a none zero audio data should also be done.

The biggest problem I can see with this approach is that certain devices could give off white noise constantly. e.g. microphones and lead to it being the one selected instead. This is however quite easily mitigable with the introduction of a white/blacklist.

This second process is needed as the deadlock is still going to happen (unless you can fix the upstream issue) therefore it must be multithreaded so the watchdog code is not within the current rendering code. This polling rate of the devices in the watchdog process should be user configurable just like FPS currently is. It should try to be in real time but it doesn't need to be so even if it's not fully fixed it's mitigable via user configuration.

The current latency is Σ O(input device) while after this change should bring it down to O(current device). It's not O(watchdog) + O(current device) as the watchdog is another process and pushes the state to the parent process which can get the result in O(1) time. The stutter is completely removed :) This does lead to the issue that the device currently used is not up to date but at most it's out of date by O(watchdog).

The advantages of this approach is that this allows panon to be self healing. Other small visual bugs like the below will also be fixed. Such as when I change audio devices and panon just freezes on the last frame rendered.

Issue #26 could also fixed for example.

Do you like my very long bug reports with suggestions and extra info? Or do would you prefer I just kept it short? Personally as a dev I would my reports to be like how I've made mine but I understand if you don't :)

Describe the bug
When switching to "Mixing all features" for PulseAudio the visualiser is delayed by about three seconds from the audio playing (I can test this by pausing and playing a song). This does not happen when using the other options.

I'm running Manjaro KDE with versions:
Plasma 5.20.5
KDE 5.78.0
Qt 5.15.2

I can't get panon to work: it just displays the following error:

I tried both installing panon from aur and installing dependencies with pacman and plasmoid from the plasma UI, but I always get the same result.

HI GUYS !

I am newbie on Linux
I want panon on my desktop, but i am facing some error
i dont know to fix that

MY full SYSTEM SPEC is as followed -

OS: Arch Linux / Manjaro kde
kde framwork - 5.88.0
Plasma - 5.23.3

FULL SYSTEM specs :-
Operating System: Manjaro Linux
KDE Plasma Version: 5.23.3

Graphics Processor: Mesa DRI Mobile Intel® GM45 Express Chipset

I installed Panon from KDE WIDGET STORE
I got this following ERROR :-

Error: Failed to load the visual effect. Please choose another visual effect in the configuration dialog

HOW CAN I FIX THIS !!

THANKS !!

Desktop (please complete the following information):

• OS: Arch Linux
• KDE Plasma Version 5.21.5
• KDE Frameworks Version 5.82.0
• Using pipewire-pulse instead of pulseaudio

Describe the bug
While using the PulseAudio backend the plasmoid only uses the default audio device regardless of what's set in the config window.

Plasmoid Viewer Log
panon.log

Is it possible to add an option to keep above all other windows? Or perhaps configure it as a window so the option is available?

That would be amazing! Thanks

I wish the widget would not occupy any space when there is no audio signal, so no empty space in the bar when there is no spectrum to show

Desktop:

• OS: Manjaro
• Plasma 5.22.5

The bug
Panon is set to auto hide the visualizer when no audio is playing. The visualizer does not hide, and the thin lines that the bars in ba1ch move don't all settle back down and instead stay stuck on the screen. Here's a screenshot:

Any error message shown in the console
No error messages

• OS: openSUSE Tumbleweed
• Plasma Framework: 5.75.0
• Latte-Dock: git-20201009

Memory continues to build when placed in a latte-dock panel. Latte-dock will easily build up to 3GB+ of RAM usage only when panon is active. Memory stops increasing as soon as panon is removed from the panel.

Desktop (please complete the following information):
Manjaro
Kde Framework 5.76.0
Describe the bug
If I restart my pc,I have to re-select which audio device it displays

Any error message shown in the console
I can't do this right now,it says that I need the plasma-sdk,but I already have it,I can look later how to fix this.

I put this widget on latte-dock panel, and the widget keeps making the panel crash when change the panel layout.

Desktop (please complete the following information):

• OS: Arch 5.12.13-arch1-2
• Version of Plasma Framework: 5.83.0
• Back-end: PulseAudio (Mixing All Speakers)

Describe the bug
Panon only detects new devices when it starts. If a bluetooth / jack / different audio output device is connected while panon is already running, panon won't react to that output stream.

Steps to reproduce

• Have one device connected and add change your back-end & your panon input device to Mixing All Speakers
• Start playing some music
• Connect the second output device and switch to it
• panon won't react to your music even if music is playing
  

I followed the README.md and saw these outputs from the terminal:

Just cycling through hues isn’t advisable for visualizations due to the wildly fluctuating perceived lightness.

See here for a stackoverflow post about why and suggestions what to use (twilight or husl seem to work well).

Describe the bug
Running panon causes popping and static to happen with audio streams that are usually fine.

pulseaudio -k // refresh the daemon and kills panon
pacmd list-sinks | grep latency outputs:
pre panon reinit and just playing music in Tauon music box

current latency: 95.26 ms
configured latency: 90.00 ms; range is 0.50 .. 341.33 ms
analog-output: Analog Output (priority 9900, latency offset 0 usec, available: unknown)

reinit panon > back-end > input device > Monitor of SONATA Audio Analog Stereo

current latency: 10.60 ms
configured latency: 6.94 ms; range is 0.50 .. 341.33 ms
analog-output: Analog Output (priority 9900, latency offset 0 usec, available: unknown)

For some reason when panon is running it will reduce the latency all the way down to 6.94 (and it always seems to be 6.94 when most latencies will change over time)

current latency: 42.61 ms
configured latency: 36.00 ms; range is 36.00 .. 341.33 ms
analog-output: Analog Output (priority 9900, latency offset 0 usec, available: unknown)

This DOES change. It seems like for whatever reason panon triggers a lower constant latency for a certain time. After a while it'll go back to dynamic latency and level out to around 40ms

Interesting observation

This seems to be improper handling of the rendering pipeline; polling something at my screen's refresh rate (144Hz). Might be an upstream issue from some libraries used but it does level out eventually and the popping stops. After a bit more testing this is directly related to the FPS set in panon (60fps will give 16.67ms constant for a bit) and not from your display, drivers, or anything else.

My hardware is a SONATA HD PRO at 384KHz and s32le. Don't think there is anything else strange about my setup but here is the pulse config anyway.

not sure it is an issue in panon or something that is misconfigured in my system, but if I mute the microphone I don't see any spectrum even though I have audio signals going on.

for the case it is important, my audio system is based on pulseaudio.

Panon used to work fine. After a reboot, I suddenly got equalizer feedback from microfon.
I lowered the volume of the microfon, but Latte Dock was then reloaded. After that, panon did not work anymore.

I think front end ist wokring, because I see bars. ButI think it is not connected to the Back end.

I tried to deinstall it and re-install it. 0.4.2 and 0.4.6

Not sure how it may look like, but that could be an interesting minimalistic option to make panon less salient in monocolor panels

This is maybe the weirdest bug I have reported so far.
In Plasma 5.19 the system monitoring plasmoids got a revamp. Now all of them are just a plotter of different system stats.
But that causes a particular bug: when both panon and network monitor plasmoids are loaded, if sound is coming out the network plasmoid registers a steady ~ 300KiB/s download/upload traffic, even when there is no actual connection (tried even disconnecting the ethernet cable). If you open other network monitoring tools (like ksysguard) you can see there is no such network traffic at all.

Here is a video I recorded of the issue on a clean user to prove it isn't releated to configs: https://youtu.be/ly8ZyutRec8

Describe the bug
In the browsers and music players, the widget works perfectly fine.
However, when I play music from Spotify, the widget starts to lag heavily.
I tried all the different settings but the issue seems to stay and it's kinda bugging me
because I use mostly Spotify to listen to music.

Currently, I’m using panon as a two bar centered setup for an overhaul, alternative to glava. 

However, since it’s a Plasma widget, fully transparent spectometer ¨à la¨ glava isn’t possible.

(Except if I’ve badly done the process in the wiki Troubleshooting guide. It gives me an error :

QML Loading error : file:///home/pm/.local/share/plasma/plasmoids/panon/contents/ui/main.qml:17:5: Property value set multiple times)

So, here's my suggestion. Could you implement a toggle to invert the spectometer? Low-pitched on the right and high-pitched to the left etc...

I suppose this can be done as an external fx effect edit, but I think others could benefit from such a small feature.

Describe the bug
The default option doesn't work very well. When I select it, it picks the mic up first.

Also after the audio device change it will stay on the old one.

I guess this can be looked as one bug or I'm misunderstanding the settings. What I want is that the visualiser will just visualise whatever is currently playing. The mix setting is a work around but seems like a waste of CPU and I don't like my mic in the mix.

Maybe add a mix what you want setting? or like a tier list of the devices. If this device is not playing, switch to the other one.

Describe the bug
When I play a pure sinewave I should only see one hump going up, because sinewaves don't have any harmonics. Panon displays this correctly, but only if the volume of the sinewave is below a certain level. If it's above that level, it starts showing a bunch of incorrect harmonics,
This is what it shows when I play a single sinewave at 155Hz at a low volume (this is displayed correctly):

This is what it shows when I play a single sinewave at 155Hz at a higher volume (notice how there are many more humps that shouldn't be there):

We have only speaker Audio that is great but only microphone one will be great too.
Adding 2 widgets one to show internal audio and the other for the microphone will be great.
