Reference-grade spatial audio — engineered for calibration, composed for listening.
What began as a structured library of test signals and demonstration assets for Dolby Atmos playback has grown into something broader: a catalog spanning calibration material, spatial sweeps, and original Atmos compositions now in regular rotation on Apple Music and other streaming platforms.
The channel still serves its original purpose — evaluation, preview, and educational use in Atmos-capable environments. Alongside that, releases like Grand Orchestral Fanfare and Deep Note (THX Tribute) explore what reference audio can become when treated as composition rather than test material.
Typical content includes:
Dolby Atmos speaker identification and routing tests
Pink noise and spatial sweep demonstrations
Calibration and alignment reference signals
Original and experimental Atmos compositions
