Het kon beter, maar heb het maar snel ineen geflanst
het werkt in ieder geval wel.

Rechtermuisknop op een lege plek in nautilus (file browser) en kies voor "Document aanmaken" -> "Nieuw bestand"
Op het nieuwe bestand klik je dan nogmaals met de rechtermuisknop en je opent het bestand in een tekstbewerker/teksteditor zoals gedit
dit in lege tekstbestand plakken:
#!/bin/bash
# simple mp3gain nautilus script
# for normalizing mp3 files
#
# written by Wesley S. (profox@ubuntu-nl.org)
#
# released under GPLv2
# feel free to use in any way
#
# Requires: mp3gain, mp3gain-gui (python, qt)
~/mp3gain-gui/mp3gain-gui "$@"Opslaan onder de naam "MP3Normalizer"
En je kan vanaf nu rechterklikken op 1 of meerdere mp3 bestanden en kiezen voor: Scripts -> MP3Normalizer (niet-mp3 files worden automatisch genegeerd)
Nu nog de scripts uitvoerbaar maken:
Rechtermuisknop op de bestanden mp3gain-gui en MP3Normalizer -> eigenschappen -> rechten -> overal een vinkje zetten bij uitvoeren
heb je dat gedaan?
Dat was ik vergeten erbij te zetten -- nu aangepast
------------
dit laatste kan ook via terminal, maar terminal is ouderwets
chmod +x ~/.gnome2/nautilus-scripts/MP3Normalizer ~/mp3gain-gui/mp3gain-guiIk hoop dat jullie er wat aan hebben... Het is vrij basic en het is geschreven in Python/Qt -- dit is trouwens de allereerste keer dat ik iets in Qt probeer. Veel mensen zullen liever een Gtk versie hebben gezien, maar persoonlijk vind ik Qt veel beter om in te programmeren... Als ik zin heb maak ik ook wel een Gtk versie. Er is niet zo erg veel specifieke Qt code.
Edit: Eerst natuurlijk die map aanmaken
thx bartek, was het vergeten in de "howto" te zetten
