Struct PannerBlock

pub struct PannerBlock<S: Sample> {
    pub position: Parameter<S>,
    pub azimuth: Parameter<S>,
    pub elevation: Parameter<S>,
    /* private fields */
}

A spatial panning block supporting stereo, surround, and ambisonic formats.

Stereo Mode

Position ranges from -100 (full left) to +100 (full right). Uses constant-power pan law for smooth transitions.

Surround Mode

Uses Vector Base Amplitude Panning (VBAP) with azimuth and elevation. Supports 5.1 and 7.1 speaker layouts.

Ambisonic Mode

Encodes mono input to SN3D normalized, ACN ordered B-format. Supports 1st through 3rd order (4, 9, or 16 channels).

Fields

position: Parameter<S>

Pan position: -100 (left) to +100 (right). Used in stereo mode.

azimuth: Parameter<S>

Source azimuth in degrees (-180 to +180). Used in surround/ambisonic modes. 0 = front, 90 = left, -90 = right, 180/-180 = rear.

elevation: Parameter<S>

Source elevation in degrees (-90 to +90). Used in surround/ambisonic modes. 0 = horizon, 90 = above, -90 = below.

Implementations

impl<S: Sample> PannerBlock<S>

pub fn new(position: f64) -> Self

Create a new stereo panner with the given position (-100 to +100).

pub fn new_stereo(position: f64) -> Self

Create a new stereo panner with the given position (-100 to +100).

pub fn centered() -> Self

Create a centered stereo panner.

pub fn new_surround(layout: ChannelLayout) -> Self

Create a surround panner for the given layout.

Supports Surround51 and Surround71 layouts. Uses VBAP (Vector Base Amplitude Panning) algorithm.

pub fn new_ambisonic(order: usize) -> Self

Create an ambisonic encoder for the given order (1-3).

• Order 1: First-order ambisonics (4 channels: W, Y, Z, X)
• Order 2: Second-order ambisonics (9 channels)
• Order 3: Third-order ambisonics (16 channels)

Uses SN3D normalization and ACN channel ordering.
