Hello 
I managed to write a little script to run cava in transparent terminator profile.
Please test it if you can…
#!/bin/bash
#: Usage: transparent-cava (height in pixels) (width full or half)
#: example transparent-cava 100 half
#: default is 200px height and full width
CONFIG_DIR="$HOME/.config/terminator"
CONFIG_FILE="$CONFIG_DIR/cava-transparent"
if [ ! -f $CONFIG_FILE ]; then
cat <<EOF > ${CONFIG_FILE}

dbus = False

show_titlebar = False
scrollbar_position = hidden

CAVA_HEIGHT=${1:-200}
CAVA_WIDTH=${2:-full}
WIDTH=$(wmctrl -d|grep "*"|awk '{print $4}'|cut -d'x' -f1)
HEIGHT=$(wmctrl -d|grep "*"|awk '{print $4}'|cut -d'x' -f2)
TOP=$((HEIGHT-CAVA_HEIGHT))

if [ "$CAVA_WIDTH" != "full" ];then
LEFT=$((WIDTH/4))
WIDTH=$((WIDTH/2))
else
:
fi
terminator -b -g "${CONFIG_FILE}" -T cavatransparent --geometry "${WIDTH}x${CAVA_HEIGHT}+${LEFT}+${TOP}"
Please save above code as transparent-cava in ~/bin directory, make it executable and test.
Usage:
transparent-cava #without arguments it defaults to 200px height and full width
transparent-cava 100 half # 100px height half width
Picom must be enabled to have transparency effect.
Cava config I use

## Configuration file for CAVA. Default values are commented out. Use either ';' or '#' for commenting.

[input]
# Audio capturing method. Possible methods are: 'pulse', 'alsa', 'fifo', 'sndio' or 'shmem'
# Defaults to 'pulse', 'alsa' or 'fifo', in that order, dependent on what support cava was built with.
#
# All input methods uses the same config variable 'source'
# to define where it should get the audio.
#
# For pulseaudio 'source' will be the source. Default: 'auto', which uses the monitor source of the default sink
# (all pulseaudio sinks(outputs) have 'monitor' sources(inputs) associated with them).
#
# For alsa 'source' will be the capture device.
# For fifo 'source' will be the path to fifo-file.
# For shmem 'source' will be /squeezelite-AA:BB:CC:DD:EE:FF where 'AA:BB:CC:DD:EE:FF' will be squeezelite's MAC address

[output]
# Output method. Can be 'ncurses', 'noncurses' or 'raw'.
# 'noncurses' uses a custom framebuffer technique and draws only changes
# from frame to frame. 'ncurses' is default if supported
#
# 'raw' is an 8 or 16 bit (configurable via the 'bit_format' option) data
# stream of the bar heights that can be used to send to other applications.
# 'raw' defaults to 200 bars, which can be adjusted in the 'bars' option above.
; method = ncurses
# Visual channels. Can be 'stereo' or 'mono'.
# 'stereo' mirrors both channels with low frequencies in center.

# Ascii max value. In 'ascii' mode range will run from 0 to value specified here
; ascii_max_range = 1000

# Use decimal value in ascii table (i.e. 59 = ';' and 10 = '\n' (line feed)).
; bar_delimiter = 59

[color]
# Colors can be one of seven predefined: black, blue, cyan, green, magenta, red, white, yellow.
# Or defined by hex code '#xxxxxx' (hex code must be within ''). User defined colors requires
# ncurses output method and a terminal that can change color definitions such as Gnome-terminal or rxvt.
# if supported, ncurses mode will be forced on if user defined colors are used.
# default is to keep current terminal color
; background = white
; foreground = green
# Gradient mode, only hex defined colors (and thereby ncurses mode) are supported,
# background must also be defined in hex or remain commented out. 1 = on, 0 = off.
# You can define as many as 8 different colors. They range from bottom to top of screen

[smoothing]
# Percentage value for integral smoothing. Takes values from 0 - 100.
# Higher values means smoother, but less precise. 0 to disable.
; integral = 77
# Disables or enables the so-called "Monstercat smoothing" with or without "waves". Set to 0 to disable.
; monstercat = 0
; waves = 0
# Set gravity percentage for "drop off". Higher values means bars will drop faster.
# Accepts only non-negative values. 50 means half gravity, 200 means double. Set to 0 to disable "drop off".
; gravity = 100
# In bar height, bars that would have been lower that this will not be drawn.
; ignore = 0
[eq]
# This one is tricky. You can have as much keys as you want.
# Remember to uncomment more then one key! More keys = more precision.
# Look at readme.md on github for further explanations and examples.
; 1 = 1 # bass
; 2 = 1
; 3 = 1 # midtone
; 4 = 1
; 5 = 1 # treble
After some more testing and integration with tint2 volume executor menu I plan to ship it with mabox-tools update.
@ben_chile big thanks for the idea and sharing important info
