Vsound is a Linux/Unix application which allows you to digitally record the output of another program such as RealPlayer. The recorded output can be saved to a WAV file or can be piped into another program such as an MP3 encoder.

Latest Version: vsound-0.6.tar.gz 10 July 2004


  • April 14th, 2006 - All web pages now moved to http://www.vsound.org/
  • October 10th, 2004 - Realplayer 10/Helix Player - I've had a few reports that the -t/--timing option no longer works with Realplayer 10 but doesn't seem necessary. Just drop the -t and it should work. Another user has informed me that using the -d/--dspout also solved this problem.
  • July 10th, 2004 - Version 0.6 released. Added --autostop option which will kill the player after a set number of seconds of inactivity (defined as the time that the /dev/dsp device is closed). Fixed the non-functional --resample option.
  • December 28th, 2003 - Added the autostop patch from Richard Taylor to download section.
  • December 18th, 2002 - Web page and source code now mirrored at http://www.zorg.org/vsound/
  • October 27th, 2002 - Erik de Castro Lopo stops maintaining and hosting vsound
  • December 11th, 2001 - Version 0.5 released. Added --timing option for streaming RealMedia files. This option prevents the realplayer from trying to download the streaming data faster than realtime.
  • November 12th, 2000 - Version 0.4 released. Many changes to allow piping vsound output to another program.
  • August 3rd, 2000 - Version 0.3 released. New features include the option of re-sampling the output file to a different sample rate and optional simultaneous audio and file output.
  • June 8th, 2000 - Real Networks releases version 7 beta 2 of their RealPlayer. The new version still works with vsound but it seems as if they have removed the ioctl() calls which broke the original version.
  • March 14th, 2000 - Released patch level 2 which works with version 7 of the RealPlayer.
  • March 4th, 2000 - Released patch level 1 which works with version 6 of the RealPlayer.
