Forum: etree Subject: cleaning the music collections: redoing old mp3's


The Archive is working on cleaning up the music collection so we do a better job of presenting it in our upcoming player. (yippie!).

There are some obsolete derivative mp3's around that we are looking to upgrade. When we say "obsolete" it is because they have not been made with these filenames for years.

Specifically:
track_vbr.mp3 and
track_64kb.mp3
are no longer made and only
track.mp3
is made

our idea is retroactively apply this to existing items. This will make filenames consistent and shorter.

Any comments?

I think 'freshening up' the music file collection and the derivative mp3s is a good thing. with file types evolving over the years, having the track_64kb.mp3 file around still doesn't make sense (originally for those on dial up connection back in the early 2000's).

Here's an example of a 'current derivative' show:

Here's an example of the old 64kb.mp3 style derivatives from 2003 (derivatives run in 2007 I think)

I assume the track.mp3 that is still made still uses the variable bit rate encoding (VBR) but just the system doesn't append the file name with 'vbr' like it did in the old days to differentiate between the _vbr and _64kb.

I say roll it out LMA wide and freshen up the file sets!

(I assume it will also get rid of the old _64kb_mp3.zip files but the _vbr_mp3.zip will get re-generated and kept still, as is the case with current show derivatives).

then I say hit derive.php on the whole LMA and let it run! probably will take a week or so to re-generate everything and then we can chase the few weird hickups, but I think its a good thing! probably end up with space afterwards as well given that there will be a whole bunch of 64k mp3s and 64k mp3 zips that will no longer be on the servers ... (not that space is an issue it seems, and this won't open up 'that' much).

Will this have an effect on files in the collection of Old Time Radio such as these shows?

Thank you for bringing this up, those are important items and important cases.

No, the mp3's would not be effected because they were uploaded as mp3's, so no mp3 derivatives will be made.

I believe ogg's might be made, which is helpful to those that stay with patent-free formats.

Does that make sense?
