Pazera Free MP4 to MP3 Converter

Pazera Free MP4 to MP3 Converter is a free program that converts MP4, M4A (iTunes audio files), M4B (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 output files based on chapters stored in source files (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 and click the CONVERT button on the toolbar. More advanced users can customize many encoding parameters: audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range and other.

• Updated conversion engine (FFmpeg) and multimedia information library (MediaInfo).
• New MP3 encoder settings: stereo mode (L/R stereo, joint stereo), encoding algorithm quality, lowpass filter.
• Displaying the output directory on the title bar of the Output panel. This directory is also displayed when the panel is collapsed, so you no longer have to expand it to see where the resulting files will be saved.
• Changes in the information module:
  For easier identification, video streams are now highlighted in red, audio - green, subtitles - purple, chapters (menu) - blue.
  The window layout is now saved to the configuration file and restored the next time the program is started.
• When turning on dark visual styles, the main window icons are slightly darkened to reduce the contrast.
• New translation: Slovenian.
• New About window displaying additional information.
• Lots of smaller improvements.
• Support for Windows XP was dropped. Windows Vista or later is required. Maintaining compatibility with Windows XP would prevent the use of new technologies, audio and video encoders, and new FFmpeg features only available for Windows Vista and newer.
