MP3 2 Ogg Lab

MP3 2 Ogg Lab is an application that you can use to convert audio tracks from the MP3 format to the OGG extension.
The interface of the tool is simplistic and easy to navigate through. Audio tracks can be imported into the list by using the file browser only, since the "drag and drop" method is not supported. Batch processing is allowed.
In the list you can check out the title and length of each song. Once you determine the output destination, you can proceed with the conversion process.
In addition, you can go to the "Options" area and enable MP3 2 Ogg Lab to automatically calculate the quality values as well as configure the encoder quality setting, transfer ID3 tag information to the output track, and more.
During the encoding task you can view the total job time duration and number of files to convert, current position and file name, estimated and remaining time, as well as a progress bar. Plus, you can pause the task.
The audio conversion program takes up a very low amount of system resources, quickly finishes an encoding job and generally manages to keep a pretty good sound quality. However, it slowed down the tempo of one song during our tests, it doesn't come with a help file (clicking the option didn't do anything) and its interface needs some minor improvements. We recommend MP3 2 Ogg Lab with reservations.
