IEM Plug-in Suite v1.15.0 vst vst3 au aax lv2 bundle Windows MacOS [FREE]

The IEM Plug-in Suite is a free and Open-Source audio plugin suite including Ambisonic plug-ins up to 7th order created by staff and students of the
Institute of Electronic Music and Acoustics.

Featured Plug-ins
DualDelay
The DualDelay has been one of the first plug-ins in the IEM Suite. Therefore it was time for a big makeover! It has been optimized to suite needs of composers and musicians by adding a sync-to-DAW function, a tap delay button as well as moving from milliseconds to BPM with multiplies for setting times. As cherry on top, it doesn’t only support a rotation of the signal, but also warping!

GranularEncoder
The GranularEncoder is an Ambisonic granular synthesis plug-in. That’s right, it is the first Ambisonic synthesizer plug-in released in the suite! The best thing about it: you can use any mono or stereo audio signal, and turn it into an enveloping sound scene, or crush the signal into microscopic sonic particles!

MultiBandCompressor
The MultiBandCompressor is a very handy tool in your project’s mastering stage! It works like a stereo multi-band compressor, however, it will make sure the spatial image is not altered! The Ambisonic input signal is split up into four bands, which can be compressed individually.

StereoEncoder
Use the StereoEncoder plug-in to encode mono or stereo audio signals into the Ambisonic domain – up to 7th order. The interface lets you easily set the orientation, width and rotation of the stereo pair. With a simple double-click onto the SpherePanner you can change the display to a linear elevation, which gives you a higher accuracy towards the horizon.

With help of the Quaternion input, you can use use data from orientation trackers (e.g. headtrackers) to steer your source into the right direction.

RoomEncoder
The RoomEncoder is so far the most complex and computation-intensive plug-in within the IEM plug-in suite. It allows you to put a source and a listener into a virtual shoebox-shaped room and render over 200 wall reflections. Perfect to enhance the externalization of binaural playback.

You can move the source and the listener freely within the room, which will automatically generate Doppler-shift effects. Use the overall reflection coefficient and the low-shelve and high-shelve filters to change the character of the reflections.

But thats not all: The RoomEncoder can make use of DirectivitySignals as an input signal. This means that your source can have a frequency-dependent and time-variable directivity. The DirectivityShaper plugin is a good tool to create various directivities.

AllRADecoder
With the AllRADecoder you can design an Ambisonic decoder for an any desired loudspeaker layout using the AllRAD approach.

The resulting decoder is automatically applied to the incoming Ambisonic audio stream, so it can be directly inserted into a decoder track of your audio project. You might also want to use it as a standalone application to design a decoder and write it into a JSON configuration file for the use in other plug-ins (e.g. SimpleDecoder).

EnergyVisualizer
This plug-in is perfect for metering the spatial image. The EnergyVisualizer visualizes the energy distribution on the sphere of the Ambisonic input signal. The energy levels are color-coded according to the color map. The Ambisonic Signal is decoded using 480 virtual loudspeakers with a subsequent RMS calculation and OpenGL visualization.

NOTE: Breaking changes!
Version v1.15.0 and v1.3.0 have introduced some breaking changes! Projects using one of the previous versions might not work as expected. For more information see the Breaking changes article and/or the ChangeLog.

Changelog:

Info for Windows installer
With v1.15.0, the plug-ins are deployed for Windows with an installer. If you have installed previous versions, you might have to remove the old version first. Otherwise you DAW might not find the new version of the plug-ins.

Experimental AAX builds
The AAX version of the IEM Plug-In Suite is available for use in Pro Tools Ultimate 2023.06 or newer. Note that these are experimental builds and may not be fully functional. Please report any issues you encounter.

For Linux users: The plug-ins and standalone versions are available soon as Debian packages.
