Yes, I'm planning to make a standalone spectrum analyzer - PeppySpectrum the same way as the PeppyMeter was made as a standalone program by minor refactoring of the Peppy Player VU Meter screensaver.

I was thinking about improving the spectrum analyzer UI but always found more interesting things to do

Best regards

Also I'll center the meter on screen if the screen resolution is larger than the meter resolution. I can also add the ability to call the external script when you touch the screen (in case of touchscreen). Do you think it can be helpful for switching screens?

Best regards
Hello, thank you so much for your efforts, it works good for me.

Sooo...

1. *PLEASE* make the touch screen to change meters,
2. Yes waiting for the analyzer too.
3. I use it as VUmeter to my DIY amps, using a USB audio card as input. I notice there is a small delay from actual music, I don't know if anything can be done.

Hi,

Good to know that you find it useful.
I'll try to implement a meter switching by touch in the next version. Though I'm not sure how to exit from meter in this case
Regarding a stand-alone Spectrum Analyzer, I'm not sure that that will happen this year. We will see...

Which display do you use for VU Meter? If that's a touchscreen with SPI interface then there can be delay between audio and meter. I didn't observe delays with HDMI touchscreens. Which software and USB card do you use?

Best regards

Could exit be done with a hot key? <CTRL>-X or smth? Or double click?
Display is HDMI
I have tried 3 USB cards, one from official store and right now Icy Box. I don't use any other software only peppyalsa and peppymeter

Playing with this on a Pi Zero with Hyperpixel 4" touchscreen.

It paints the meter backgrounds without issue, the pipe is working fine, but animations don't work, never see a needle or moving "lights" on the bars.

A print(r) statement in update_rectangle() method of component.py shows the data flowing through, but no animation:

I've never used Pygame 2 though I'm not sure if that can cause any issue as they promised that it will be backward compatible. Could you try to use the 'noise' data source to eliminate the pipe from the equation? For that set the 'type' to noise:
