Here is the web browser user interface for the SurroundPod main menu:

HDMI Audio

SurroundPod’s primary output is HDMI, delivering up to 9.1.6 Dolby Atmos test signals and media playback directly to any A/V receiver, processor, or display. Full bitstream passthrough ensures your AVR decodes the original format — Dolby Atmos, Dolby TrueHD, DTS-HD Master Audio, and lossless PCM all reach your processor exactly as authored. Plug directly into any HDMI input and SurroundPod becomes the source for test signals, calibration media, and reference content — no additional hardware required.

AES67 Network Audio

SurroundPod supports up to 34 channels of AES67 over Ethernet, allowing you to send test signals and tones to any channel in a high-channel-count system, including Dante devices with AES67 enabled.

AirPlay to HDMI

Stream stereo audio from your iPhone, iPad, or Mac directly to SurroundPod and out over HDMI. Use any AirPlay-compatible app — music streaming services, your personal library, demo content, or client material — and route it instantly through the A/V system you’re calibrating. This makes SurroundPod a practical playback bridge for any room: walk in, connect your device, and start listening through the full processing chain without uploading files or carrying a separate source.

External Storage Playback

Plug an SSD into any USB-A port and play your music or video collection in any supported format, including 9.1.6 Dolby Atmos. Bring your library to any venue or production studio, connect to an HDMI port, and listen to your reference material instantly.

Browser and App Control

SurroundPod is controlled over the network via a browser or one of our supported apps. The browser interface provides access to the Test Signal generator, Sine Generator, Music Player, and Video Player in HDMI mode, or Test Signals and the Sine Generator in AES67 mode. In AudioTools, SurroundPod integrates directly into modules like FFT and RTA, allowing you to control channel selection for pink noise or engage the music player without leaving your measurement workflow. In HAA CinemaTools, every test module selects the appropriate signal and allows direct selection of any 9.1.6 channel for test signals during calibration, or any 7.1 channel for real-time generated signals. Transfer Function in AudioTools supports real-time fixed-latency pink noise streaming, so a separate reference signal connection is not needed for synchronous tests.

Wi-Fi and On-Site Setup

SurroundPod ships wired, and Ethernet always takes priority — the sensible choice for an installed system, and a requirement for AES67. But not every job has a network. Turn Wi-Fi on and SurroundPod will join your own network or a client’s. Arrive somewhere with no network at all and it creates its own: the connected display shows the Wi-Fi name, password, and a QR code, so you join from your phone and open the control interface with nothing else on site. It steps aside automatically as soon as a known network or an Ethernet cable appears. The radio is off until you switch it on, so an installed unit behaves exactly as it always has.

Surround Test Signals

Test signals are available in 5.1, 7.1.4, and 9.1.6 formats:

• Pink Full Band — SMPTE standard pink for channel frequency response adjustments. Fully non-coherent when multiple channels are playing.
• Pink Mid-Band — Industry standard for setting channel levels.
• Polarity — Our proprietary polarity signal for use with AudioTools or HAA CinemaTools.
• Impulse — Use with ETC to plot room decay.
• Sine Sweep — Use with Impulse Response for multiple room acoustics measurements.
• LARSA — For use with our Loudspeaker And Room System Analyzer module.
• LARSA Delay — Test signal for LARSA in delay test mode, to measure relative channel timing.

This is the web browser test signal user interface:

Sine Generator

Generates sine waves from 10Hz–20kHz with smooth sweeping for rattle tests and subwoofer checks. Can be assigned to any 7.1 channel. Because sine waves are generated in real-time rather than played from a file, channel assignment is limited to 7.1.

Video Media Player

Play video files in multiple formats over HDMI. Upload your own content to build a video library that is always available without the need for internet access. The 1TB model also comes with over 20 SD and HD video calibration patterns. Lossless soundtracks are sent to your processor untouched, not converted to stereo. Play a Dolby TrueHD, Atmos, or DTS-HD Master Audio clip and your AVR receives the original bitstream and decodes it exactly as authored — the same soundtrack your client will hear, from a box that fits in your kit bag. At 1080p and below you get the picture and the original soundtrack together. 4K files are sent as sound only, or as picture with stereo if you prefer — your choice, switchable in the interface. Still images display too. Drop BMP, JPG, or PNG files in alongside your video and call them up the same way, for logos, custom patterns, or reference stills. Supported containers:

• MP4, MKV, MOV, AVI, WebM, M4V, TS (transport stream)

Supported codecs:

• H.264/AVC, H.265/HEVC, VP8/VP9, MPEG-2/4, ProRes, and more

Transfer Function Audio Streaming

SurroundPod supports Transfer Function measurements by streaming a pink noise reference signal over the network to any 7.1 channel. This eliminates the need for a separate audio input connection for synchronous tests. When connected to SurroundPod, Transfer Function in AudioTools or HAA CinemaTools streams pink noise to the selected channel, which also serves as the reference signal. Like the sine generator, streaming is generated in real-time, so channel assignment is limited to 7.1. To measure subwoofer delay, first select the center or left channel and turn the sub off. Then run the Delay Finder in Transfer Function and set the delay. Start the test, and save the test by holding the folder icon for a few seconds. Place the cursor on the crossover frequency. Now switch to the Lfe channel and turn the sub back on. Do not move the microphone. Run the test, and observe the phase shift and slope of the curve at the cursor. If the phase shift or slope does not coincide with the saved plot, adjust the sub delay until it does.

Display Mode Control

Switch between SDR, HDR10, and HLG output modes to match your calibration workflow. SurroundPod sends HDR infoframes over HDMI, triggering the correct processing mode on any connected display or AV processor — the same capability found in dedicated pattern generators costing thousands more. Advanced settings allow custom configuration of max luminance, min luminance, Max CLL, and Max FALL values for precise HDR metadata control.

Video Calibration Pattern Generator

Generate professional video test patterns directly over HDMI — no files or external sources needed. Patterns render in real time at 1080p or 4K resolution and are controlled from the browser or app interface. Available patterns include:

• Color Bars — SMPTE, SMPTE HD (RP 219), PAL 100%, and RGB Test
• PLUGE — Black level setup pattern for display calibration
• Grayscale — Smooth grayscale ramp and 11-bar IRE steps (0–100% in 10% increments)
• Color Ramps — Individual red, green, and blue gradient ramps
• Geometry — Crosshatch grids (fine and coarse) and checkerboard for convergence and overscan
• Window & Patch — Adjustable window from 1–100% with X/Y positioning, custom foreground and background colors, IRE and RGB sliders with fine-adjustment nudge controls, and color presets for grayscale tracking, near-black steps, primaries, secondaries, and skin tones

Included Video Calibration Files

Over 20 professionally authored video calibration files are pre-loaded across 1080p and 4K resolutions, including white clipping, black clipping, color clipping, sharpness, overscan, alignment, skin tone, scene reference, grayscale ramp, grayscale steps, SMPTE color bars, SMPTE HD bars, window patterns, primary and secondary color fields, near-black ramp, and checkerboard patterns.
