This free software effortlessly converts MP4, M4A, M4B and AAC files into MP3 or WAV format. It also allows users to extract original audio tracks and split files based on chapters commonly found in M4B files while maintaining sound quality.

One of the application's features is the ability to split files based on chapters that are typically found in M4B files. Metadata are also transferred from the source files aside from the option of adding customized tags. The software utilizes the latest version of the LAME encoder to convert audio streams to MP3.
Encoding parameters are customizable and can be adjusted by more advanced users, including audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range, and many others. The program supports CBR, ABR, and VBR encoding, depending on LAME presets.
The software is user-friendly, with a simple operation. Users only need to drag and drop the files into the main window and click on the CONVERT button. At default settings, the program converts files to MP3 with a constant bitrate (CBR) and automatically selects encoding parameters that ensure original audio quality and the smallest MP3 files possible.
Overall, Pazera Free MP4 to MP3 Converter is a reliable program that can meet the needs of both basic and advanced users. Its features, quality conversion, and user-friendly interface make it a top choice for those looking for a free program to convert their audio files into MP3 or WAV format.
