ogm file
I use audiograbber, but not sure of its capabilities regards ogm.
This is the 'help' section for ogg:
A new interesting compression format is OGG Vorbis. It gives better sounding files than MP3 and the main advantage is that it is completely royalty free and open source (Fraunhofer has some patents regarding MP3 in some countries). There are 4 different official dll's that are used for OGG encoding/decoding. Ogg.dll, Vorbis.dll, Vorbisenc.dll and Vorbisfile.dll. The Vorbisfile.dll is not used for encoding and thus not used by Audiograbber. These dll's can be found at OGG Vorbis homepage at
http://www.vorbis.com. You can also get a plugin there to play OGG files if your player program does not yet support OGG.
These 4 dll's are quite large and I think it is clumsy with 4 different dll's but fortunately John Edwards (homepage:
http://homepage.ntlworld.com/jfe1205/) has made a special dll that contains all 4 dll's. This dll is named LibVorbis.dll and is now included in Audiograbbers setup file.
If LibVorbis.dll is found then Audiograbber uses that dll. If it is not found then Audiograbber looks for Ogg.dll, Vorbis.dll and Vorbisenc.dll and uses them instead (if they are found on the computer).
OGG Vorbis will be listed on MP3 settings, Internal encoders when found on the computer.
Tips: If you have problem to set an exact quality with the slider then select the slider and use the left/right arrow keys to fine tune the settings.
