After the audio book files are imported into ViWizard AA Audiobook Converter, you should click the Format panel at the bottom left of the conversion interface and choose the output format from the pop-up window. The default output format is lossless which will generate the unprotected audiobook files without downgrading the original audio quality at all. Currently, it supports a large number of output formats, including MP3, M4B, AAC, WAV, WMA, M4R, M4A, FLAC, OGG, and other popular formats. For lossless output, you can't customize the bit rate, channel, codec, and sample rate.

Before starting the conversion, you can click the Edit icon listed in each column of the audiobook file to split the audiobook into several small segments via chapter or time frame. In addition, you can adjust the volume, speed, and pitch of the audio book. And you can personalize the tag information of the audiobook file.
