Spatial Audio Decoder

Tetra Spatial Decode

Quadraphonic and Ambisonic Web Audio panner. Simulates frequency-isolated 808 sub-bass routing across 4 virtual coordinate nodes.

Drag the source node (purple) inside the coordinate frame. Virtual speakers are placed at the corners.

Panner Controls

Sub-Bass Isolation 80 Hz LPF
Signal Frequency 336 Hz / 55 Hz

Generates a dual-tone signal mixing ZYNTHIO reference 336 Hz carrier with a deep 55 Hz (A1) sub-bass oscillator.

Ambisonic Mapping

Calculates spatial gains dynamically based on relative distance of the coordinate point to the four virtual speaker placements (Front-Left, Front-Right, Rear-Left, Rear-Right).

808 Sub Isolation

Integrates a dedicated 24dB/octave Butterworth low-pass filter to isolate core sub-bass frequencies, keeping high-frequency transient click localized.

Sovereign Audio Node

Designed for multi-speaker arrays and spatial music release cataloging on the SongPal records ecosystem.
