The whole trick is to select those bitrate value to get good sound quality at a relatively small size of the resulting file. But on the other hand, the higher bitrate, the larger output file. Generally, the higher bitrate, the better sound quality in the output file. The most important audio conversion parameter is audio bitrate. The program can extract the audio tracks encoded in the following formats: MP3, AAC, M4A, OGG (Vorbis), AC-3, PCM (WAV), AMR. If you want to extract the original audio track from the video file without loss of sound quality, select Try extract original audio stream on the Output format list. You can manually set the encoding parameters on the Audio and Additional settings panels, or just select one of the predefined profiles from the Profile list. If you ran the program for the first time and have not changed any conversion parameters, will be used default settings.Īt 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 To run the conversion, on the list must be at least one file, moreover, it must be checked in the column with check boxes (the 2-nd column on the picture above). When you do this, the program will add your selected files to the processing list. You can also add files to the list using the drag and drop technique. Will be displayed a standard dialog box for file selection, in which you have to select one or more audio or video files, and click Open button. To do this, click the Add files button on the toolbar. To convert MP4, M4A, M4B, M4R and AAC files, you must first add them to the list.
