liq-tag-removal

I created a script designed to remove all liq_ tags from Azuracast media files. This can be useful if you previously enabled the "store tags to file" option in Azuracast's older autocue.cue_in implementation. These tags conflict with the updated Azuracast Rolling Release, which uses Liquidsoap 2.3.x's autocue.internal. It also comes with a dry run feature to initially check your files without making any changes.

Caution

Backup your system / audio files first!

Important

Please also ensure that you have cleared the Extra Metadata in Azuracast's Media File Manager, as older versions of Azuracast may have stored these values there as well:

Media > Music Files > set search to show ALL > select ALL > More > Clear Extra Metadata

Install script

cd /var/azuracast
wget https://raw.githubusercontent.com/RM-FM/liq-tag-removal/main/liq_tag_removal.sh
chmod +x liq_tag_removal.sh

Start a dry run

Check whether your files have related meta tags set. Replace {my_station_short_name} by your station short name (URL Stub).

/var/azuracast/liq_tag_removal.sh --dry-run --path /var/lib/docker/volumes/azuracast_station_data/_data/{my_station_short_name}/media`
