Dynamic Naming - Changing just the Encoder tag

[EatAPeach]

I currently have my FLAC files named Album Artist - Album Title (Year) [Encoder] {Catalog ID] / Track Number - Track Title.

I am converting my FLAC files to MP3 320 and want to keep everything exactly the same except the Encoder (FLAC -> MP3 320) so

Original filename: Album Artist - Album Title (Year) [FLAC] {Catalog ID] / Track Number - Track Title.
Renamed filename: Album Artist - Album Title (Year) [MP3 320] {Catalog ID] / Track Number - Track Title.

Is this possible? I can get everything how I want it with the tag and property functions, but the Catalog ID is missing; so if I could only change the encorder that would be perfect.

[album artist] - [album] ([year]) (FLAC -> mp3 320) [tag]catalog #[]/[track] - [title]

your naming string can be typed fixed text like above.

I currently have the following: [TRIMFIRSTFOLDER][TRIMFIRSTFOLDER][TRIMFIRSTFOLDER][origpath][][][]\[origfilename] ; I was hoping I could keep this since it does everything I want it to, but change the [FLAC] portion of the original folder/directory name to [MP3 320].

Can I apply a programmable action to the origpath or origfilename?

If using Origfilename then cannot insert items into, unless there is a fixed existing string, try, to replace FLAC in the string:

[REPLACE]FLAC,FLAC -> mp3,[origfilename][]
