Podcast manipulatie script

Al sinds 2005 gebruik ik Juice, nu al een paar jaar versie 2.2. Waar ik die versie vandaan heb weet ik niet meer maar op sourceforge staat nog steeds versie 2.0.
Maar goed, nadat de bestanden gedownload zijn wil ik ze eerst uniform maken.
Sommige MP3's hebben namen van meer dan 100 karakters lang.

Zoals deze van meer dan 150 tekens, waarbij de tekens in rood tracking tekens zijn:

dailysourcecode-231472-05-15-2010_pshow_352992_dopvhost_media_podshow
_com_doppl_0f98d82d4477dccd4427dc9d013759b3d0f252c2_dopsig_e2705c144
ee77c66df70c7a296d17c94.mp3

Dat vinden mijn iRivers niet zo fijn, dus breng ik die bestandsnamen terug naar maximaal 60 tekens.
Daarna maak ik de bestanden kleiner door ze naar 32kb/s mono te converteren.
De Podcasts waar ik naar luister zijn toch alleen maar gesproken woord (m.u.v. de DSC)...
Omdat Lame (bij het converteren) niet zo'n goede job doet om de podcasts allemaal even luid te laten klinken gooi ik de gekrompen bestanden door mp3gain heen. Hierdoor klinken de Podcasts allemaal even luid en hoef ik niet steeds aan de volume knopjes te zitten...
Lame verliest bij de conversie de ID3 tags, daarom kopieer ik, na de conversie, de ID3 tag van het oorspronkelijke bestand naar het nieuwe gecomprimeerde bestand.

Ik heb de programma's allemaal in "C:\Program Files\MyPrograms\" staan.
De programma's zijn:
id3.exe http://home.wanadoo.nl/squell/id3.html
lame.exe http://lame.sourceforge.net
mp3gain.exe http://mp3gain.sourceforge.net/

Processing mp3 files after downloading them with Juice.
I listen to podcasts and I want all files to be small, so I can carry many of them on my iRiver. For that reason, I reduce the file lengths to a maximum of 60 characters, then I have lame convert the files to 32kb/s mono.
In the process the ID3 tags are lost, so I resolve this by copying the ID3 tags from the original files to the reduced files. (The message from Lame.exe is: Be aware that the ID3 tag is currently lost when transcoding.)
In order to make them all sound equally loud I run them through mp3gain.
