Hi , just want to create an action
I Have several files of different format (dsf,flac,mp3) and want to add to the album title
Add (DSD) when the it's .dsf
Add (24 Bits) when it is .flac and the bitrate is over 2000
I don't like to use Filter add the bottom
Would be faster to create a new action
Thank you
Martin

Did you know that there is a field %\_bitspersample% that is probably more accurate than the manual assignment? It does not exist in MP3 files.
Also, there is the the field \_TAG that contains the information FLAC or DSF (i think) so you can add that to the album.
With these 2 fields you do not have to mess about with the filename.

See the FAQs for that:
[/t/967/1](https://community.mp3tag.de/t/967/1)
The 3rd example is how to append a string to a field. Instead of the example "xyz" use the field variable, probably %\_tag% and/or %\_bitspersample%.
If you enclose the %\_bitspersample% in square brackets, [%\_bitspersample%] it gets treated like an "if" condition.
