SAP 7100X

Sound takes shape in computation.

Scroll from incoming samples to weighted mixing, filtering and time alignment — then follow the sound out.

  1. 01

    Receive

    Four TDM16 inputs receive up to 64 channels of digital audio.

  2. 02

    Process

    The Router connects the selected processing modules. Cortex-M0 configures their parameters.

  3. 03

    Deliver

    Eight TDM8 outputs deliver up to 64 channels to external conversion and amplification.

The Router connects selected processing resources; the three modules are not a mandatory sequence.

Functional illustration, not a measured waveform or silicon floorplan. Cortex-M0 configures registers, coefficients and routing; it is not in the audio data path. FIR profiles describe internal resources, not TDM I/O counts. Input and output support Gain / Mute.

Spatial rendering / real installations

A coordinate system for real spaces.

The desired sound position and the installed loudspeaker position are different things. Rendering connects the two through a configured output layout.

SPATIAL COORDINATESPosition relationship
Separate sound positions, loudspeaker positions and the listening referenceCyan circles show two input sound positions. Eight white squares show an example physical loudspeaker layout. A gold cross marks the fixed listening reference. The vertical axis indicates elevation.

  1. 01

    Define the input direction

    Input Layout describes the azimuth and elevation of each audio track.

  2. 02

    Configure the real layout

    Output Layout describes loudspeaker positions, distances and channels. Distance uses a fixed listening reference.

  3. 03

    Calculate and synchronize

    Calculate Decoder creates the decoder configuration; Sync To Device sends it to SD64. Continue with on-site verification.

From installation to parameters

Work with the layout you have.

Configure the installed loudspeakers instead of assuming a single room geometry. The software exposes azimuth, elevation, distance and output channel for the actual system design.

The listening reference defines distance; this illustration does not imply automatic listener tracking or show a measured acoustic result.

A standard. A richer way to create.

NGA Next-Generation Audio Standard

Describe sound as spatial objects and connect rendering to the actual loudspeaker layout.
