This is a program started in 2012 by Christophe Leblanc using Flowstone from DSP Robotics. It is distributed for free.

This software is only available on Windows operating systems.



FlowPlayer is a "portable" software that requires no installation. It can be dropped into any directory. However, to be able to benefit from a better support of the MP3 format, it requires the use of the small program "mpg123.exe" (supplied with). "mpg123.exe" is intended to be in the same directory as FlowPlayer by default, but this option can be changed (if necessary) in the software option panel. For convenience, you can drop the FlowPlayer folder into an installation folder and call FlowPlayer using a shortcut.


FlowPlayer should benefit from the next evolution in the coming months:

  • New DSP effects and analysis racks (scope, spectrum, etc ...).
  • Possibility to interchange the DSP racks without removing them.
  • More options and backup possibility.

And why not?

  • Better integration with the operating system.
  • A VST plugin version (at least for rack system and effects).
  • Multi-effects presets.
  • An easy skin / personalization system.
  • One or more audio inputs with mixer.
  • Management of streaming or integration with streaming softwares.
  • 2D / 3D sound visualization effects.

If you think that all these evolutions, or others, are useful, consider contributing to the financing of this software!
