Overview
Video Capture records a video on your phone with your device's live readings drawn right on top of the footage, so voltage, temperature, volume, and the audio oscilloscope/FFT appear burned into the saved video. It is built for showing off a build, making demo clips, and documenting a problem for support. Open it from the Record tab in the AuralSync app bottom navigation, or from the camera button on any connected device's page.
This is different from Recording Sessions, which logs your device's numbers as reviewable data. Video Capture produces a normal video file you can share anywhere; Recording Sessions produces a data log you review in the app or on the web portal.
The readings are drawn into the video itself, so there is no separate overlay file and nothing extra to line up afterward. What you see on screen is exactly what ends up in the saved video.
What You Can Overlay
The panels available depend on which device you are recording. The app only offers the readings your device actually reports.
| Panel | Shows | Devices |
|---|---|---|
| Voltage | Live voltage with a rolling graph, the session high/low, and the graph's current range | Any device that reports voltage (WVC, WVC-PRO, HPVM, HPPM) |
| Temperature | Each connected temperature probe's reading | WVC-PRO, WTH, WDD |
| Volume | Master volume, or one bar per channel group when you have groups set up | WVC family |
| Oscilloscope | The live audio waveform for each channel, with the channel's peak voltage | WVC-PRO, SSA |
| FFT | The frequency spectrum for each channel | WVC-PRO, SSA |
A branding line you can edit and an LF Audio badge round out the layout, along with the device name (or names, when you record more than one device at once).
Starting a Recording
From the Record tab
Use this when you want to choose exactly which devices and readings appear.
- Open the Record tab in the bottom navigation.
- Your connected devices are listed. Turn the switches on for the sensors you want to overlay from each device.
- Tap Launch camera.
- Grant the camera, microphone, and photo-library prompts the first time (see Permissions below).
From a device's page
Use this to quickly record a single device.
- Open the device from the Devices tab.
- Tap the video-camera button in the top bar.
Either way, the camera opens full screen with your readings already overlaid on the live view.
The Camera Screen
The camera preview fills the screen and your selected readings are drawn on top. A small toolbar sits along the edges:
| Control | What it does |
|---|---|
| Record | Starts and stops the recording. |
| Flip camera | Switches between the front and rear cameras. |
| Settings | Opens Overlay Settings (which readings appear). |
| Move/Arrange | Turns the layout editor on and off so you can reposition panels. |
| Close | Leaves Video Capture and returns to the app. |
Arranging the Overlay
Tap the move/arrange control to enter the layout editor, then position each panel however you like:
- Drag a panel to move it. Panels snap to a grid so they line up cleanly and sit flush next to each other without overlapping.
- Pull the corner handle to resize a panel. Width and height are independent, so you can make an oscilloscope panel wider without stretching the text.
- Tap the branding line to type your own text (a shop name, a build name, anything you like). It is remembered for next time.
Your layout is saved per device, so each device keeps its own arrangement whether you record it on its own or alongside others.
Make the panels you care about large and drop the ones you don't need, so the numbers read clearly when the video is played back on a phone.
Overlay Settings
Open Settings from the camera toolbar to choose what appears. When you have more than one device selected, each device gets its own section.
- Turn each reading on or off (Voltage, Temperature, Volume, Oscilloscope, FFT).
- Oscilloscope and FFT channels — show every channel or just the ones you want.
- Voltage min/max + range — overlay the session's lowest and highest voltage plus the graph's current scale on the voltage panel.
- Oscilloscope peak voltage — show each channel's peak voltage on its waveform panel.
- Channel names — show or hide the per-channel and oscilloscope/FFT labels.
- Device labels — when recording several devices, tag each panel with its device name.
Changes take effect immediately on the live preview.
Recording and Saving
- Frame your shot and arrange the panels the way you want them.
- Tap Record. A timer appears while recording.
- Tap Record again to stop.
- The video is saved to your phone's photo library (on Android, into an album named LF Audio).
On iPhone, saving a finished clip to your photo library can take a few moments after you stop, especially for a longer recording. Wait for the save to complete before leaving the screen.
The overlay is already part of the saved video, so you can share it straight from your Photos or Gallery app.
Recording Multiple Devices
From the Record tab you can turn on readings from several connected devices and record them all in one video. Each panel is tagged with the device it came from, and the bottom of the frame lists the device names (shortened to fit alongside the LF Audio badge). This is useful for showing a multi-amp build, or a base station and its sensors together.
Permissions
Video Capture needs three permissions, requested the first time you open the camera:
| Permission | Why |
|---|---|
| Camera | To show and record the live view. |
| Microphone | To record sound with the video. |
| Photos / Gallery | To save the finished video (add-only; the app cannot see your other photos). |
If you decline a permission, you can still open the camera, but you may be asked again, or you can enable it in your phone's Settings for the AuralSync app.
Tips and Troubleshooting
A quiet audio channel shows a small oscilloscope trace rather than a full-height one, matching how your device's own screen displays it. A full, active signal fills most of the panel.
If the camera preview looks frozen after you switch to another app and come back, close and reopen Video Capture; the camera reconnects on its own.
Recording the camera plus live oscilloscope and FFT is demanding. On a warm day or a long recording, the phone may heat up; keep clips reasonably short if you notice it getting hot.
