SimpleVST has released five free audio effects for Windows – duuaal, spaank, praamp, muun, and urrth.

Here’s what they have to say about them:

• duuaal — a two channel amp with built in reverb.
• spaank — amp which offers a fixed mid voicing yet a very responsive bass and treble eq.
• praamp — preamp with tone knob to lighten or darken the sound, boost knob pushes the amp into its sweet spot.
• muun — a simple overdrive that has a mind of its own.
• urrth — a very simple circuit spiced to taste that provides a decent foundation to build on.
