The interface is very simple and self explaining. There is a field for input files, a field for an output path, and the lists with preconfigured profiles. If you want to change default theme, go to Options → Theme.
Click the upper Add files... button to select an input audio file(s) from your computer.
Input file formats: *.aac, *.ac3, *.aiff, *.ape, *.flac, *.m4a, *.m4b, *.mka, *.mp3, *.ogg, *.ra, *.tta, *.wav, *.wma.
By default the output file name is the same as audio title is. If you want to change it click the Output Name... button. A new window will be opened.
There are some parameters in it (Name Prefix, Postfix and others) which you can set as you like.
In the bottom of this window you can see the pattern of the output file name. It's formed according to the current options.
Note: the pattern is the same for all output files during one session, it's not allowed to set the unique pattern for each file.
Click the Browse... button and choose the location where you would like to save your converted audio files. Click Ok.
If you want to access the output folder content, click Open.
In the list of Formats select an output audio format.
In the list of Presets select one of the available pre-configured presets.
For advanced users: read this guide for information on how to customize a preset or create a new one.
If you want to convert files to MP3 format you can add more information about your output audio files.
Click the tags... button and set the Title, Album, Artist and other parameters as you want.
By default the program will automatically fill the title tag and the artwork, taking a snapshot from the middle of video which can be seen in iTunes, Winamp, Windows Explorer.
Click the Convert button along the bottom of the interface and wait just a few seconds.
Note: Before clicking the Convert button you can set to turn off computer after the process is completed. Just go to Options... and make sure the appropriate box is checked.
