Bfxr

This is one of the better versions of SFXR. The history feature is really handy. Used this and the original many times. Great tool for game jams.

Really takes you back to windows 98 days.

This is a classic already, have used it for several projects and produces great results quickly :)

A snazzy GUI is pretty cool!

No go. Requires Flash player to try.

Seems a bit complicated.
