Spatial audio encoder (or decoder) is a technique used to compress and transmit audio signals while preserving spatial information and allowing surround audio playback.

The spatial audio encoder uses advanced algorithms and signal processing techniques to analyze audio signals and extract spatial characteristics such as sound direction, distance, and room reverberation. By encoding this spatial information along with the audio content, it enables the recreation of a three-dimensional sound field during playback.

Specifically the binaural spatial audio encoder plugin is used to encode audio signals of different formats (stereo, quad, 5.1, 7.1, ambisonic…) to a binaural format. In this sense, the spatial audio encoder translates a spatial audio format into the binaural format.

The plugin works by using Head Related Transfer Functions (HRTFs), which allows the plugin to recreate the sense of audio spatiality relative to the listener’s head.

E4L Master Bus

Max for Live

Ableton Live

The E4L Master Bus is also responsible for decoding these 16-channels of Ambisonics audio into a selected output format. These outputs may be routed to dedicated soundcard outputs, or monitored via Ableton’s main stereo bus.

binaural panner is a tool or plugin used in immersive audio to position audio sources within a three-dimensional space and create a binaural audio experience. It simulates the way human ears perceive sound by applying HRTF (Head-Related Transfer Function) filters to audio signals, resulting in a spatialized sound perception when listened to through headphones.

The binaural panner takes audio input and allows the user to control the placement and movement of sound sources within a virtual soundstage. It applies spatialization techniques to modify the audio signals, taking into account parameters such as azimuth (horizontal angle), elevation (vertical angle), and distance from the listener’s perspective.

Unlike a binaural panner, which focuses on the precise placement and movement of audio sources within a stereo field, a binaural spatialization engine offers a more comprehensive set of tools and functionality. It includes features such as HRTF-based spatial rendering, taking into account factors such as interaural time differences (ITD) and interaural level differences (ILD), as well as room simulation, distance modeling, and reverberation.

Envelop for Live (E4L)
Source Panner | Mono Panner | Stereo Panner

Max for Live

Ableton Live

Envelop for Live (E4L) is an open-source audio production framework for spatial audio composition and performance. Envelop for Live operates within the music production environment of Ableton Live 10+ and Max for Live. Envelop for Live is designed to be a highly modular, flexible platform for artists to compose and perform spatial audio, and for developers to create new kinds of audio effects for the Ambisonics domain.

The E4L Mono Panner is a basic spatialization utility. It takes a mono input signal (stereo signals are automatically collapsed to mono) from a regular Ableton audio bus and spatializes the sound into a 16-channel Ambisonics signal that will be routed to the E4L Master Bus.

The Heads-Up Display indicates the positioning of the sound sources. The mouse may be used to click and drag the position of the sound source.

Envelop for Live is a binaural panning plugin and an ambisonic suite of tools.

dearVR MICRO was designed to easily integrate with any standard DAW and mixing workflows.
To begin with, one can think of the plugin as a replacement for the built-in stereo pan knob. In your digital audio workstation, select a mono or stereo audio track and set its integrated pan to zero, or “center.” Then create a new instance of dearVR MICRO as the last plugin insert for the track.

The plug-in can be approached in the same way as a normal panner, only now with full three-dimensional space there are limitless creative possibilities that extend well beyond the scope of a simple stereo panner.

dearVR MICRO is the replacement for SENNHEISER’S AMBEO ORBIT once the Sennheiser brand partnered with dearVR.

Natasha: Binaural Ambience Modeling


Windows, macOS

Natasha is a binaural environment modeling plug-in. Inspired by a binaural microphone built in our studio and also in one of our rooms.



Windows, macOS

SoundObject creates a binaural sound with the senses of three-dimensional sound localization from a monaural acoustic source and its positional information. It supports headphones-based as well as stereo speakers-based 3D spatial sound. Furthermore, it could also support headphones monitoring of stereo speakers sound.

Conventional three-dimensional binaural sound processors implement sound localization with the convolution of an acoustic source and head-related impulse response (HRIR) that represents scattering by the head. Since the convolution consumes a large amount of computational resource, SoundObject assumes that scattering by a head consists of scattering by a rigid sphere and pinnae (earlobes), then enables sound localization with simplified sphere and pinna scattering effect filters.

++binaural is a filter which places a sound at a specific position around the listener’s head. It does this by using filters which simulate the filtering effect of the head and outer ear for sounds at all angles. The filters in ++binaural are optimized for headphones and are only for 0 degree elevation at a 44100 sample rate. Future versions of ++binaural will contain multiple elevations and sample rates.

Binaural Location


macOS, iPod touch, iPad, iPhone

Binaural Location goes beyond the simple pan control; it allows you to place your audio at a specific location anywhere in a virtual space around the listener. The location of the L and R control points on the screen controls the location of two virtual speakers. Based on the angle and distance from the speakers to the listener’s ears, the app creates a realistic impression that the sound is actually coming from the specific location of the L and R points.

This is an audio unit plugin that runs in host apps such as GarageBand. It does not run as a stand-alone effect.


VST, VST3, AU, Unity Package

Windows, macOS

Anaglyph is part of an ongoing research effort into the perceptual and technical capabilities of binaural rendering. This audio plugin was designed both to support ongoing research efforts as well as to make accessible the fruits of this research to audio engineers working in DAW environments. Amongst its features, Anaglyph includes a personalizable morphological ITD model, near-field ILD corrections and HRTF (Head-Related Transfer Function) parallax selection, a localisation enhancer, an externalisation booster, and multiple HRTF support via the SOFA file format.

Eigen Space Simulator


Windows, macOS

Play, Render, and Analyze. These three modes are able to perform a selection of different “space-aware” processes; Play does accurate early reflection processing in real-time, Render computes high-quality reverb impulse responses for you to use in convolution reverbs (or in Eigen itself, if you want), and Analyse checks your virtual space to see how sound resonates against it.

Eigen’s main mode allows for real-time (and accurate) early reflection processing. The depth of your reflections are determined via a knob on the bottom, and you can control the sound source & listener positions with our super cool 3D object positioner. You can even change the angle that you are looking at the controls from.

A Manual is bundled with both the demo and full versions as a .pdf file.


Spatial Audio Processor

A spatial audio processor is a broader term that encompasses various techniques and tools used to manipulate and enhance the spatial characteristics of audio. It involves encoding, decoding, and processing audio signals to create a sense of space and immersion. Spatial audio processors may include techniques such as Ambisonics, object-based audio, or room simulation algorithms. Its goal is to recreate a realistic audio environment by simulating sound reflections, room acoustics, positioning of sound sources, and other spatial properties.

Unlike Binaural Panner and the Binaural Spatialization Engine which focus on binaural audio output, spatial audio processors include binaural processing and other spatialization methods.
