Description

Free WMA to MP3 Converter – Quick start

Free WMA to MP3 Converter is a free program that converts Windows Media files (WMA, WMV, and ASF) 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 input 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).

At 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.

Basic operation of the program is very simple: just drag & drop WMA, WMV or ASF files into main window and click the Convert button. All parameters of the conversion program will set automatically in order to preserve sound quality.
More advanced users can customize many encoding parameters: audio bitrate, bitrate mode, number of audio channels, audio sampling frequency, volume, time range and other.

Note!
Some older MP3 players can play MP3 files encoded only at a constant bitrate – CBR.

3rd party software

To encode the video files the program uses the FFmpeg encoder (ffmpeg.org).

To retrieve information about video files, the program uses the library MediaInfo.dll (http://mediainfo.sourceforge.net/).

The program is accompanied by a special version of the FFmpeg encoder, adapted to the needs of the program. Not recommended to use other versions of FFmpeg.

Changelog

Version 1.6 (2019.12.07)

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.
