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).
The application supports over 70 audio and video formats, including AVI, MP3, FLV, MP4, MKV, MPG, MOV, RM, 3GP, WMV, WebM, VOB, FLAC, AAC, M4A.
In addition, the program allows you to split input files based on chapters (often found in audiobooks).
The program has a number of predefined settings (profiles) specially designed for novice users. While more advanced users can customize audio encoding parameters used by encoder: audio bitrate, sampling frequency, audio channels, audio volume. The application allows to extract/convert full audio track or selected range only.
The application interface is very simple and user-friendly. To convert or extract audio tracks from audio/video files, just drag & drop them into main window, select proper profile from list, and click the "Convert" button. If the audio quality is poor, increase audio bitrate.
