The OagMachine

Media converters are some of the most popular applications you might find on the Internet, mainly because some files need to have a certain format in order to be played on specific players.
One application that could help you with that is The OagMachine. It's a small application that allows you to convert various files to OGG Vorbis or AAC format.

Compact but confusing user interface

The application installs quickly but it sports a really compact and rather confusing graphical interface with only a few features at hand. It offers direct access to all of its sections, but it would have been nice if it had a toolbar.
It doesn't come with any tips or instructions on how to use the application and all of its features. However, it comes with a command line component which allows you to make conversions faster.

Convert files fast

You simply need to browse your computer and load the files that you would like to convert. It comes with the option to convert AC3, MPA, MP2, MP3, VOB, AVI, WAV files to OGG Vorbis or AAC format.
You can choose the destination folder for output files on your computer and it allows you to change the name of resulted files. It allows you to make some adjustments to your files, you can change  Azid Downmix levels, adjust SSRC options and set the sampling rate to a certain level.

Make some adjustments to output files

It allows you to adjust the volume, use partial encoding features, enable channels, dynamic compression, hybrid gain, normalize the file to a certain level or adjust the file quality. It allows you to manage AAC encoding options and save a log file.
However, it doesn't come with a built-in player for previewing files and batch conversion isn't supported. All in all, The OagMachine is a useful program for converting files to OGG Vorbis or AAC format, but it needs a nicer interface and some more tools.
