Description

Free MP4 to MP3 Converter is a program that converts MP4M4AM4B (audiobooks), M4R (ringtones) and AAC files to MP3 or WAV format. In addition, the program lets you copy (extract) original audio tracks without any loss of quality.

The program also allows you to split input files based on chapters (often found in M4B files).
Metadata by default are copied from the source files, but the user can add their own tags.

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).

Basic 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  button.
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 is available in 32 bit and 64 bit version. The conversion process of the 64-bit version is faster by a few to 20%.
