This would make it possible to add a contrib script which would reload barva at, for example, the beginning of a track in order to mimic the colours of the track's album art.

I tried barva on my ArchLinux with default configuration and it only set terminal background to black.

I inspected the content of the buffer after get_samples(s, sample_chunk_size, buffer); in src/main.c, the values are all below 0.01 even if the music is reasonably loud, i.e.:

0.004364
0.005371
0.006134
0.006500
0.007019
0.007416
0.007568
0.007629

Maybe the reason is I'm using headphones. As a result, queue_mean is less than 0.01, color_mean always returns 0 or 1 and the background is set to black or almost black.

If I multiply the value in src/color.c by 100, it works like a charm. Since it works for others as is, I propose to add an option to specify the sensitivity – the multiplier of the value.

When I execute barva in rxvt-unicode, it does pulse on the beat of my music. However, when I interrupt the program (ctrl-c), the background of the terminal emulator returns to black instead of my original background color.

When I execute barva in qterminal, the background just stays in the original color. I executed export BARVA_SOURCE=$(/usr/share/barva/pa-get-default-monitor.sh). When I try for example rxvt-unicode, it does work.

What am i doing wrong? can i hardcode it so i dont need to set the vars ever?

thank you

Lagging looks like as if BARVA_FPS were set to something very small.

Observations:

• Running simultaneously with cava magically fixes the lagging.
• Playing some music from a web browser and then switching to Spotify fixes the lagging for a short period of time.
• Spotify Web is unaffected.

i'm using Arch + i3, i've already set the variables

on Konsole when i start barva everything work just fine, but on URXVT, nothing happens

here some comparison, on left up there's konsole with barva, left down default konsole and on right it's URXVT with barva started but no difference from normal
