Convert a file to OGG format following these steps:
Select the folder with your files in the file tree on the left. Click it to have its contents displayed in the main panel.
Select the file you want to convert and mark it (click Check button or check its checkbox below the list).
Choose OGG format in Convert option of Main Menu or press OGG button in Top Toolbar or right-click with your mouse at chosen file and choose convert to option from context menu.
Wizard dialog window will appear.
Choose Destination item and select necessary destination folder to place converted file. You can use current path or to change file name or destination.
Choose Samplerate item and select necessary samplerate. Remember that the higher samplerate, the better quality and the larger file size.
Choose Channels item and select necessary channel. Stereo channel is twice bigger then mono, but more qualitative.
Choose Quality item and set quality of converting file. Quality 0 is roughly equivalent to 64 kbps average. Quality 5 is roughly equivalent to 160 kbps, it's very-near-CD-quality. Quality 10 correspond to nearly 400 kbps. To change it you can just click in direction you need (more or less). You can also regulate quality by keyboard arrows (up-down and right-left) or by rolling mouse wheel. You also can print the number in numeric edit window.
Select Finish conversion item and check all parameters of converted file.
You can mark the fields Delete originals and Open destination folder after converting to delete originals and to open destination folder after conversion.
Press Finish button to convert files.
Tip! If you do not know what parameter to choose Wizard will automatically set the most appropriate one. All conversion parameters made are remembered so next time you want to convert files of the same source and target formats, these settings will appear (sure you may change them if you like).
