Updated conversion engine (FFmpeg) and multimedia information library (MediaInfo).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).īasic operation of the program is very simple: just drag & drop MP4, M4A, M4B, M4R or AAC files into main window and click the CONVERT button on the toolbar. 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 output files based on chapters stored in source files (often found in M4B files).

In addition, the program lets you copy (extract) original audio tracks without any loss of quality. Free MP4 to MP3 Converter (64-bit) is a free program that converts MP4, M4A (iTunes audio files), M4B (audiobooks), M4R (ringtones) and AAC files to MP3 or WAV format.
