Multidimensional Mixing

Traditional audio mixing is the art of enhancing and combining multiple sound inputs into left and right loudspeaker sends. Object-based mixing adds a multidimensional layer to that art. In addition to traditional mixing tools, each sound object can now be placed and manipulated anywhere within the 3D framework provided by the multichannel loudspeaker configuration. An object-based mix enables sources to be localized, scaled and moved to their actual location or wherever the imagination desires.

Creating a multidimensional object-based mix is extremely intuitive. As if painting, sources can simply be placed, spread and layered visually where you wish them to be heard. The distinct positions and separation of each source translate naturally so that a listener can perceive subtle compositions in the mix without the need for frequency tailoring or constant level riding. And the visuals of the L‑ISA Controller Soundscape provide real-time feedback about the spatial balance of the mix.

Given that sound objects are mixed to locations, not to loudspeakers or busses, the properties of each sound object are independent from the specific loudspeaker layout. This enables portability from show to show as the existing source spatialization can be rendered to the new sound system configuration regardless of scale.

L‑ISA offers an extraordinarily intuitive 3D mixing environment that makes the process of multidimensional mixing straightforward. L‑ISA provides the mixing engineer with five parameters for each sound object:

Pan

controls horizontal location

Width

controls perceived size, from point source to panoramic

Distance

controls perceived proximity with reverberation

Elevation

controls vertical location

AUX Send

provides a classic post-distance auxiliary bus send

The L‑ISA Processor receives a post-fader, post-processing output for each channel and creates signal feeds for each speaker or speaker group. In addition to offering real-time control of any input, parameters can also be stored in synchronization with audio tracks and then recalled as snapshots, triggered through time code, modified from sensor inputs, etc.

With L‑ISA, object-based mixing and a powerful room engine combine in a single software platform to enable both the creation of a specific audio environment and the placement of sound objects within it as core elements of delivering an engaging audio experience.
