The conversion process of the 64-bit version is faster by a few to 20%. The program is available in 32 bit and 64 bit version. More advanced users can customize many encoding parameters: audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range and other. The program supports encoding with a constant bit rate - CBR, average bitrate - ABR and variable bit rate - VBR (based on LAME presets).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.īasic operation of the program is very simple: just drag & drop MP4, M4A, M4B, M4R or AAC files into main window, select the Default encoder settings in the Profile list and click the Convert button. To convert audio streams to MP3 the application uses the latest version of the LAME encoder. Metadata by default are copied from the source files, but the user can add their own tags. The program also allows you to split input files based on chapters (often found in M4B files).
