Sordina is an instrument mute emulator.  It allows you to apply a wide range of mutes to your unmuted virtual instruments or live recordings.

Sordina works by using detailed impulse responses created through the analysis of real-world recordings of muted and un-muted instruments. The results are very accurate reproductions of the genuine mutes.

A full list of all the virtual mutes included with Sordina can be found in the user manual.


Here is a recording an unmuted trombone.

Here’s an A/B comparison of the same instrument playing with a real bucket mute and the original unmuted recording being processed by Sordina’s bucket mute emulator.

Here’s another A/B comparison of a real mute and one of Sordina’s virtual mutes. This time it’s a cup mute. Again Sordina is processing the original unmuted recording.


Audio Examples

Easy to use

Sordina has a clean, easy to use interface that helps you get started really quickly. Simply place the plugin on an instrument track, select a mute, and tweak the volume. For more detailed control over the sound there is a built-in filter and mix control knob.

The on screen meters and FFT analyser provide a real-time picture of how Sordina is colouring the incoming audio.


Mutes such as the trumpet’s harmon and plunger include a playable wah-wah control. When a compatible mute is selected the on-screen Wah knob is activated and can be controlled in real-time using host automation.


Sordina contains over 120 different brass and saxophone mutes. All of these have been carefully organised into a three tier preset browser. It’s easy to find the mute you are looking for by navigating the menus or using the built in text search. You can also mark your favourite mutes to make it even quicker to find them.

A full list of all the virtual mutes included with Sordina can be found in the user manual.

    It’s just what I was looking for! Since many virtual instrument libraries don’t include muted articulations (sometimes only a few ones) I was looking for the possibility to simulate these effects with a plugin and here it is. In my humble opinion, the results are very convincing and it includes presets for a wide variety of brass mutes adapted to each different brass instrument. I only miss that the same plugin includes mutes for the strings and thus be able to simulate the “con sordino” effect. I hope this will be included in a future update!
