Pazera Free Audio Extractor is a freeware application whose main purpose is to easily and without any quality loss extract audio tracks from video files. The extracted audio tracks can be converted to the desired format MP3, AAC, AC3, WMA, FLAC, OGG, M4A (AAC/ALAC), WV, AIFF, or WAV.

The usage of the program is quite simple. Importing videos can either by file browser or by drag and drop files into the program window. Once the video files are loaded in the list you can specify the output format or pick one of many predefined profiles. Click on the convert button will commence the audio extraction and encoding process. This audio extraction or audio encoding process can be done in batch so you don't have to do it file by file. There are no limits on how many files you can process in batch. Closing down the application or shutting down the computer once the batch is finished is also possible.

Advanced users can also change the audio bitrate, sampling frequency, audio channels or easily increase or decrease audio volume. Pazera Free Audio Extractor also allows extraction or conversion of a full audio track or selected range only. This is quite handy if you want to crop a few seconds from the beginning or from the end.

In case you want to preserve the original audio track pick "Try to extract original audio stream" as output format and the program will try to extract the audio track without any format conversion meaning that the output file will have absolutely no audio quality loss.

The application also allows you to load audio files and it can be used as a free and easy to use general audio converter.

Key Features
  • Extraction of original audio tracks from video files without any loss of sound quality.
  • Extraction/conversion of any audio track from video files containing multiple audio tracks.
  • Splitting output files based on chapters stored in the source files.
  • Support for all LAME encoder presets when converting to MP3.
  • Copying metadata from the source files.
  • Displaying detailed technical information about the source files in the File properties window.
  • Many predefined conversion profiles, with the ability for users to create custom profiles.
  • Adding files to the file list by simply Drag and Drop.
  • The program is portable, as it does not use the system registry, and all settings are stored in INI files. It can be run from portable devices like pendrives and removable drives.
  • Ability to save encoder commands to a BAT file.
  • Built-in support for multiple languages, with the current version supporting Arabic, Bulgarian, Chinese, Czech, Dutch, English, French, German, Greek, Hungarian, Italian, Japanese, Korean, Polish, Portuguese (BR), Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, and Turkish.

- Added support for files from network shares whose names start with the characters "\"
- Added support for the SoX audio resampler (libsoxr)
- "File properties" window: when saving the report to a text file, 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.
- The ability to display the system "File properties" window for a file selected on the list has been added
- "File properties" window: Displaying the CRC32 checksum and MD5 hash of files up to 200 MB in size
- Added support for additional WAV (PCM) encoders: pcm_s24le, pcm_s32le, pcm_s64le, pcm_u8, pcm_mulaw, pcm_f32le, pcm_f64le

- Improperly selected audio sampling frequencies in profiles using the Opus encoder have been corrected
- New FLAC encoder options: bit depth, compression level, audio channel mode, multidimensional quantization, precision and linear predictive coding methods and more

- The ability to convert MXF files has been added
- New language files: Slovak and Slovenian
- New About window displaying additional information
