You can try the Equalizer APO https://sourceforge.net/projects/equalizerapo/Ok, But I can't change anything in my room as per status.
Now my setup is PC>>>SwanM200KII. Instead of in-between DAC to enhance the audio quality for better crispy and more clear with software inbuilt equalizers.
it's free. It sets an equalizer at the system end, which means everything gets piped through it including any browser that you may use for YouTube and what not. It works great.
