Playback Controls

Browser Audio Capture: Select "Browser Audio" as source and click "Start Capture" to route audio from other tabs/windows (YouTube, Spotify, etc.) through your effects processor.

Important: The original audio will continue playing in the source tab. To hear only the processed audio:

Mute the source tab (YouTube, Spotify, etc.)
Or reduce the source tab's volume to minimum
Or use headphones and only listen through VORTEX

Edge Users: If you get a "Not supported" error, try selecting a tab that has audio content (like YouTube) when prompted, and make sure to allow both audio and video permissions.

🎚️ Dynamics

🎛️ Compressor

Controls dynamics and levels - reduces loud peaks, evens out volume

Threshold (dB)

Level where compression starts (-24dB = moderate, -12dB = heavy)

Ratio

Compression strength (2:1 = gentle, 8:1 = aggressive)

Attack (ms)

How fast compression reacts to peaks (3ms = fast, 30ms = slow)

Release (ms)

How fast compression stops after peak (100ms = tight, 500ms = smooth)

🛡️ Limiter

Hard ceiling - prevents clipping and distortion from extreme peaks

Threshold (dB)

Maximum output level (-1dB = safe, -6dB = conservative)

Release (ms)

Recovery speed from limiting (5ms = tight, 50ms = smooth)

🔊 Output

Restores volume lost from compression - brings level back up

Makeup Gain (dB)

💡 Purpose: Compensates for volume reduction from compression
Usage: 6dB = standard, 12dB = heavy compression recovery

Master

Volume

Immersion

Wet: 0% | Dry: 100%
Fluid Influence: 0%
