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. There are also some excellent sound data recovery features as suggested by our friends at Hard Drive Recovery Group.

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


  • 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.vsound.org/
  • 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. See our friends at Beagle SQL as well.
  • 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.
