A quick listen into your audio network. GTA CUE brings local network audio metering and listening to your iPhone and iPad. Select a compatible Dante-network source, choose a channel, check its level and tap CUE to listen. SINGLE CUE OR AN EIGHT-INPUT MIX Use Single CUE for a quick channel check, or enable Cue Mix in Options to combine up to eight inputs into a local stereo monitor mix. Choose sources and channels on the detail pages, adjust each input's trim and pan, and use Mute, Solo and channel-pair links. Four memories store assignments and controls for quick recall. Your monitor controls do not change the transmitter's audio. CUE MIX REQUIRES ETHERNET Connect a compatible iPhone or iPad Ethernet adapter to the audio network. Cue Mix offers wired Ethernet interfaces only and does not switch to Wi-Fi if the cable is disconnected. Single CUE also supports Wi-Fi through an access point connected to the audio network; congestion and packet loss can interrupt wireless audio. Bluetooth listening adds a separate output delay. LOCAL CUE SHARING Compatible GTA CUE devices on the same local network can share an available audio feed. Settings > Network > CUE Sharing shows the audio path and connected peers. Transmitter capacity and available feeds still apply. Keep a supplying device connected. Active CUE listening on iPhone and iPad can continue in the background or while locked; a silent standby does not remain available in the background. Quitting the supplying app or disconnecting its network can interrupt listeners. Restore the supplying device and reconnect when needed. YOUR LOOK, YOUR METERS Choose the dark Slate theme or the light console-inspired The Hive, with customizable knobs and meters. Use segmented RMS or analog-style metering, optional outside meters and Pre Trim/Post Trim measurement. Printed analog-face numbers are decorative. The iPad shows network, sample-rate and bit-depth information in landscape as well as portrait. YOUR CONNECTION Choose your network adapter and match the source with manual 44.1, 48, 96 or 192 kHz selection. Receive supported 24-bit or 32-bit signed-integer PCM streams. Inspect packet and playback diagnostics, and optionally scan a reachable IPv4 range for compatible sources. LOCAL BY DESIGN Audio decoding, metering and playback run locally. No account, ads, analytics SDK or developer-operated cloud audio service is required. A clearly labeled, silent Demo Mode lets you explore the controls without a transmitter. BEFORE YOU BUY Real metering and listening require a compatible transmitter and access to its local network. Supported formats and capacity depend on the transmitter and configuration; selectable sample rates do not guarantee support from every source. Start CUE playback from a compatible external source. Active listening can continue while the app is in the background or the device is locked. A silent standby does not stay available in the background. Output-route changes mute listening. There is no AVB or PTP-locked output. Monitor protection is not calibrated hearing protection; set output volume appropriately. By GIFFTRIPPAUDIO.

Verdict

The call

The clearest difference is price: RDTap at Free against GTA CUE's $19.99. RDTap also leads on iOS requirement (15.0 vs 17.0). GTA CUE's advantage is rating (5.0 vs 2.0) and update cadence (every 2 days vs fortnightly). On ads, in-app purchases and device support there is nothing between them.
