The program also allows you to split output files based on chapters stored in input files (sometimes found in F4B audiobooks).
Metadata (artist, title, album, etc.) by default are copied from the source files, but the user can add their own tags.

If you have a collection of music videos in FLV format downloaded from video sites (eg YouTube, Yahoo! Video, metacafe) and want to convert them to MP3, or save the original audio tracks to audio files, this program is for you!

To convert audio streams to MP3 the application uses the latest version of the LAME encoder. The program supports encoding with a constant bit rate - CBR, average bitrate - ABR and variable bit rate - VBR (based on LAME presets).

Basic operation of the program is very simple: just drag & drop FLV, F4V, F4P, F4A or F4B files into main window and click the Convert button. All conversion parameters the program will set automatically in order to preserve audio quality.
More advanced users can customize many encoding parameters: audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range and other.
