fmedia - fast media player/recorder/converter


fmedia is a fast asynchronous media player/recorder/converter for Windows, Linux and FreeBSD. Its goal is to provide smooth playback even if input device is very slow and unresponsive. The architecture allows to extend the functionality of the application in any way: adding a new audio input/output format, a new DSP filter or even a new GUI. fmedia is very small and fast: it has low CPU & memory consumption making it ideal to listen to music or process audio files while running on a notebook's battery. fmedia can decode: .mp3, .ogg (Vorbis, Opus), .opus, .m4a/.mp4 (AAC, ALAC, MPEG), .mka/.mkv (AAC, ALAC, MPEG, Vorbis), .avi (AAC, MPEG), .aac, .mpc, .flac, .ape, .wv, .wav. fmedia can encode into: .mp3, .ogg, .opus, .m4a (AAC), .flac, .wav. You'll find more detailed information about fmedia in README.txt file inside the package.



See all screenshots.


Note: it's beta version - not tested well enough, not all functions will work as expected. See section "USE-CASES" to have an idea of which features should work.

Self-contained. fmedia uses modified versions of 3rd party libraries: libALAC, libfdk-aac, libFLAC, libMAC, libmp3lame, libmpg123, libmpc, libogg, libopus, libsoxr, libvorbisenc, libvorbis, libwavpack. Everything is inside the package, so no additional dependencies are required to be installed on your system.

Portable. No installation, just uncompress the package anywhere you want!

Open-source. You can download the sourcecode from here:

  1. Unpack archive to the directory of your choice, e.g. to "C:\Program Files\fmedia"

    • Right click on fmedia package file (e.g. in Explorer
    • Choose "Extract All..." in the popup menu
    • Follow the Wizard steps
  2. Optionally, run the following command from console (cmd.exe):

    "C:\Program Files\fmedia\fmedia.exe" --install

    This command will:

    • add fmedia directory into user's environment
    • create a desktop shortcut to fmedia-gui.exe
  3. Run fmedia-gui.exe to open graphical interface; or execute commands via fmedia.exe from console (cmd.exe).


  1. Unpack archive to the directory of your choice, e.g. to /usr/local/fmedia-0:

    tar Jxf ./fmedia-0.33-linux-amd64.tar.xz -C /usr/local
  2. Optionally, create a symbolic link:

    ln -s /usr/local/fmedia-0/fmedia /usr/local/bin/fmedia


All features are provided by fmedia modules divided into 3 groups:





Note the difference between UNIX and Windows terminals when you use special characters and spaces:


Play files, directories, Internet-radio streams
