Description

Free WebM to MP3 Converter – Quick start

Free WebM to MP3 Converter is a totally free program that converts WebM, MP4, FLV and 3GP files to MP3 or WAV format. Movies in these formats are used by most popular video sites (eg YouTube, Metacafe, Yahoo! Video). Additionally, the program allows you to extract original audio tracks from supported files without loss of sound quality.

Metadata (artist, title, album, etc.) by default are copied from the source files, but the user can add their own tags or completely disable writing metadata to output files.

If you have a collection of music videos downloaded from YouTube and want to convert them to MP3, or save the original sound tracks to audio files, this program is for you!

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 WebM, MP4, FLV or 3GP files into main window and click 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.

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% compared to the 32-bit version.

3rd party software

To encode the audio 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 1.5 (2021.02.11)

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.
Information about the conversion progress is displayed on the title bar of the main window and on the taskbar.
The metadata settings are now saved to the configuration file and restored the next time the program is started.
FFmpeg encoder parameters window (F2): information has been divided into groups displayed on separate lines, which facilitates parameter analysis.
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.
Fixed Stack overflow bug when selecting next files in the list very quickly.
Added support for files from network shares whose names start with the characters “\\“.
When saving the report to a text file in the File properties window, UTF-8 encoding is used (in previous versions the system default code page was used).
After the user has interrupted the conversion, the program displays a window asking whether to delete the incompletely converted file. Such files usually have a damaged internal structure and cannot be played.
If incorrect parameters are passed to the conversion engine (FFmpeg) and the conversion process fails, the output file will be automatically deleted. Such a file usually does not contain any data (0 bytes in size) and only unnecessarily litter the disk.
Displaying additional information in the error log window.
UTF-8 encoding (instead of the system code page) is used when writing the error log to a text file.
Improved handling of user-created profiles.
Lots of minor changes and fixes to the source code and the program interface.

Version 1.4 (2019.08.22)

New conversion engine (FFmpeg) and multimedia information library (MediaInfo).
New control displaying the list of profiles. Now additional separators are displayed between the profiles, which increases the readability.
New About window displaying additional information.
Small changes to other interface elements: audio volume slider, navigation buttons, and more.
The error causing displaying of negative values of processed data after exceeding the 2GB threshold has been fixed.
Various minor improvements and bug fixes.
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.

Version 1.3 (2018.06.12)

New conversion engine (FFmpeg) and multimedia information library (MediaInfo).
New modules: Check for updates, Tools Info.
