First you'll need to clone acdb_extract. I used the one by J510-Dev which is originally based on the one by luca020400.

git clone https://github.com/J510-Dev/acdb_extract

Then, as the README says you must generate the acdb header. For Qualcomm devices? The stock audio hal would be audio.primary.msm8996.so which is found on my stock ROM from /system/lib/hw/audio.primary.msm8996.so which I could just copy into the acdb_get folder... so for example, I'd use this:
./generate_acdb_data.sh audio.primary.msm8996.so

which will generate a file called acdb_data.h which is needed for the next step.

Since acdb_extract doesn't require being built in the AOSP environment? You can just build it using...

Make sure the device's and/or commonized device proprietary-files are updated with the same blobs that you want in your proprietary vendor repo.

Next, to use the kang and section mode we need the switches "-k -s". -k tells extract-files to only kang/pull updated blobs without deleting any blobs. -s tells it to only update ones from a commented section of your proprietary-files.

for example, if i have this in my proprietary-files
