Free WebM to MP3 Converter is a totally free program that converts WebM, MP4, FLV and 3GP files to MP3 or WAV format. Movies in these formats are used by most popular video sites (YouTube, Metacafe, Yahoo Video). In addition, the program allows you to extract original audio tracks from supported files without loss of sound quality. If you have a collection of music videos downloaded from YouTube and want to convert them to MP3, or save the original sound tracks to audio files, this program is for you.
At default settings, the application converts files to MP3 with constant bitrate (CBR) and automatically selects all the encoding parameters so as to preserve the original audio quality.
Metadata (artist, title, album) by default are copied from the source files, but the user can add their own tags or completely disable writing metadata to output files. Basic operation of the program is very simple: just drag & drop WebM, MP4, FLV or 3GP files into main window and click Convert button on the toolbar. More advanced users can customize many encoding parameters: audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range and other.
