The sources receive the audio coming from the Inputs, then go through one or several spatialization bus. They offer an audio channel strip with several parameters to mix the sources. Each source encloses six panning modules, linked to the selected spatialization algorithm bus. Therefore, a source can be assigned to a maximum of six buses simultaneously.

Sources Families

HOLOPHONIX has three different sources families.

Virtual Sources

Virtual sources represent physical objects that emit sound into space. They are made of one or more (stereo, multichannel) audio source(s), and can be freely positioned around the audience. Those sources include an acoustic simulation module (with reverberation), that can be automatically controlled by the position of the source.

Ambisonic Streams

Ambisonic Stream sources are designed to receive audio encoded in a specific format. Unlike virtual sources, they do not represent a physical object in space; therefore they do not have any associated object in the Venue

Direct routings

They offer the possibility to connect audio inputs to audio outputs directly.

Check the Equalizer page and Dynamics page for more details.


Use the trim to adjust the level of the source between -80dB (no signal) and +30dB. The trim function is especially useful to minimize the level differences between the sources.


You can then use the Gain to mix source levels. It ranges from -60 dB (no signal) to +12dB, and can be accessed via the Mixer, with faders.


Use the mute function to cut the audio of a source. When a source is muted, its computation is deactivated, thus saving processing power.

Audio Parameters


Activate Solo on a source to listen to that source only. It can be activated on multiple sources at the same time.

To clear all active solos, use the Solo Clear button in the options bar.

LFE Send

LFE Send allows you to set the amount of signal to send to the LFE Bus. Sources contaning multiple channels (Stereo, Multichannel, Mic tree and Direct Routings) will send a mono sum of all their channels to the LFE. Ambisonics sources, will only send the W-Omnidirectionnal channel.

The signal is sent after the channel's Gain, Mute parameters, as well as the Direct send for virtual sources. However, the Direct Mute parameter has no effect on the LFE Send .

LFE Mute

Use the mute button to deactivate the LFE Send on the source.


Use the Routing section in the Inspector to adjust the send level to any bus the Source is connected to.
