AUDIO Cu delivers tightly synchronized, high fidelity, high resolution (Hi-Res), stereo, Dolby Digital®, Dolby TrueHD®, and Dolby Atmos® audio data over new or pre-existing power lines.

It is a superior alternative to Wi-Fi, WiSA/WiSA-e, or Bluetooth based audio protocols. AUDIO Cu does not experience radio frequency (RF) interference, structural boundaries, or distance limitations. AUDIO Cu is plug and play solution that is fortified for consumer, pro audio, and enterprise level integration. Work smarter, not harder, and move your sound over the power lines with AUDIO Cu.
Spatial Audio Preview

Spatial Audio Preview is a focused tool for hearing exactly how Apple's spatial audio renderer handles your files. Load any audio or video file and switch between Apple's Music and Movie spatial rendering profiles in real time. Spatial Audio Preview reads your file's true format — sample rate, bit depth, channel count, and channel layout, including Dolby Atmos and multichannel surround layouts — and shows you exactly what's playing. The app also tells you whether your connected output (AirPods, Beats, or other accessories) actually supports spatial audio rendering, so you always know if what you're hearing is spatialized or just raw channels being played back. Features: • Switch between Music and Movie spatial rendering modes on the fly — the same modes used by Apple Music, Apple TV, and more. • View info on the current file, such as sample rate, bit depth, channels, and layout. • Play back audio in several channel layouts, including stereo, surround, and Dolby Atmos. • See if your device and headphones support spatial audio playback. • Background playback with lock screen and Control Center controls allow you to listen with the device locked or unlocked. • Spatial Audio Preview is built with accessibility in mind with a VoiceOver-first interface. Spatial Audio Preview doesn't collect, transmit, or store any of your data. Everything happens on your device. Supported file types: • WAV • AIFF • CAF • M4A • MP4 • MOV Supported channel layouts: • Mono • Stereo • Quadraphonic • 5.0 • 5.1 • 6.0 • 6.1 • 7.1 • 5.1.2 • 5.1.4 • 7.1.2 • 7.1.4 • 9.1.6 • Dolby Atmos (E-AC-3) • Dolby Digital (AC-3)
