Ahh heres the post I was looking for. I earlier responded to a post which was last responded to in 2008. It seems theres an updated version on this page. So according to this thread it looks this enhancement never was implemented four years on.
I am strongly in favour of having this feature on MP3tag. I have a huge collection of music and I am eager to know the type of encoder each MP3 that was originally used/converted before acquiring these Mp3's rather than individually running Spectral Analysers? My intention is not to edit codec information, but rather to view it.
Currently when I choose the "Codec" column I get this:
[MPEG 1 Layer III] - this does not tell me whether the file was converted using Lame or other?
The only applicaton that I know of that shows these tags is dbPoweramp, however Im having to hover my mouse over the file to discover the encoder information (e.g. FhG, Lame 3.99r etc...) Surely there must be a quicker way.
I even tried field called ENCODERSETTINGS. I see nothing at all, nor do I see any of my 200 mp3's that I have converted into LAME in the last month.
I came across an application which looks to do the job, (software is called "Mr Questionman"), however it takes an hour to load up my entire playlist of 5000 + songs, so I uninstalled it immediately.
