Overview
The Audio panel is where AUTOVJCLUB starts listening to the room. It enables the microphone (HTTPS required, with localhost as the only exception), exposes the input level, and toggles the spectrum visualization. Because song recognition, music-change detection, and audio-driven modulation all depend on this input, this is one of the most important panels: if the audio side is unstable, everything downstream wobbles too.
Input gain has both a Manual control and an Auto Gain mode. Auto Gain follows environmental change, but in real venues with band performance and crowd cheering, levels can swing in ways that surprise it; the most stable workflow is to set a manual baseline first and only layer Auto Gain on top. The spectrum visualization is useful as a decorative layer, but leaving it always on tends to feel over-busy, so showing and hiding it per genre is often more practical. The spectrum auto rotation is available in Demo as well.
Control Reference
- LIVE badge (top right, when mic is active)
A subtle indicator that the mic stream is active and feeding the rest of the app.
- REC button (main view only)
Starts or stops microphone capture. On error the button flashes red and an error message appears below. The Control panel view replaces this with a passive notice instead, since the mic is operated from the main screen.
- Microphone error message (when an error occurs)
Localized message for permission denied, no device, or non-HTTPS origin. Sent to Sentry so the team can act on it.
- Audio level meter
Vertical bar showing real-time input level. The green-to-yellow range is the target. Pegging red means clipping; near-flat means too weak.
- GAIN slider
Sets input gain on a logarithmic scale from 0.001× to 20×. The slider position is internally normalized to 0–1000. Display formats with 3 decimal places at low values and 1 decimal at high values. Disabled when Auto Gain is on.
- Auto Gain switch
Continuously targets a stable input level. Useful for long sessions in changing rooms; pair with a manual baseline for predictability.
- SPECTRUM visibility toggle (eye icon)
Shows or hides the spectrum visualization layer. When off, the SPECTRUM controls below are dimmed.
- Mode buttons (wave / bars / mirror / dots / circle, etc.)
Switches the visualizer drawing mode. Mode-specific thickness sliders appear below.
- Auto rotation switch + interval slider
Rotates the spectrum mode over time. Interval 5–60 seconds in 1-second steps. Available in Demo as well.
- Color palette (5 swatches)
Pick the spectrum color from Cyan, Magenta, Yellow, White, or Orange. Active swatch has a white border.
- OPC slider (opacity 0–100%)
Overall opacity of the spectrum layer. Used to balance against the background video.
- LINE slider (wave / circle modes, 1–10 px)
Stroke width for waveform-style modes.
- BAR slider (bars / mirror modes, 0.2–3×)
Bar width multiplier.
- DOT slider (dots mode, 1–10×)
Dot size multiplier.
- Collapse arrow
Minimizes the panel.
When To Use It
Before going live, target a level meter that sits in the green-to-yellow range and set the gain there first. Too low and recognition hit-rate drops; too high and audio modulation becomes hyperactive and tiring to watch. Band changeovers and DJ swaps shift the level balance, so checking the meter at every transition tends to keep recognition reliable. If the microphone refuses to start, the most common causes are missing browser permission and a non-HTTPS origin.
If a workflow is unclear or missing, send feedback from the in-app Feedback panel.
