Solved MPD Server + NCMPCPP player: Apply ffmpegs anequalizer filter

[SDK Chan]

For my headphones I now managed to set up MPD in real time as non-root, and get ncmpcpp connected and work.
I also created a 10 band equalization filter with ffmpegs anequalizer.
The problem is I do not know how to apply it so that it sticks each time I restart ncmpcpp.
This is the filter chain I created:

# 10 band parametric equalization will be used

# Each equalizer band is separated by ’|’

# Audio Output ################################################################
#
# MPD supports various audio output types, as well as playing through multiple
# audio outputs at the same time, through multiple audio_output settings
# blocks. Setting this block is optional, though the server will only attempt
# autodetection for one sound card.
#
# OSS audio output through headphones filtered
#
audio_output {
type "oss" # Sound Driver where the filtered output goes through
name "OSS Headphones" # Devive name
device "/dev/dsp8" # Headphones device
mixer_type "hardware" # Preferred mixer method (Another alternative is "software" as mixer_type)
mixer_device "/dev/mixer8" # Mixer used for headphones
# mixer_control "vol" # I will set my volume per audio output as needed

# Toggle filters as needed
#filters "utopia-2022-eq-version-1" # Filter in use for the headphones
filters "utopia-2022-eq-version-2" # Filter in use for the headphones
}

EDIT:
I managed to load the filter, but somehow the audio does not play.
Everything works now with my equalization applied.
Recalculated the bandwith (parameter w in anequalizer in Hz) based on the electric engineering formula (Fmaxn - Fmaxn-1) starting from band 2 to get the exact route width from one graph node to another graph node.
