Shared Mode
AutomixerShared Mode is a gain sharing automixer algorithm. A gain sharing automixer automatically distributes a constant total gain across multiple active microphones, reducing the gain of unused microphones in real time. This approach helps to minimize feedback, lower ambient noise, and prevent comb filtering, making it especially effective in unscripted discussions involving up to eight microphones in acoustically treated spaces.
Weight
| Parameter Name | Parameter Range | Parameter Definition |
| Weight | -40 - 6 dB | Weight determines the relative priority of each microphone by setting its side-chain level in the control system, allowing certain channels to have more influence in the gain-sharing process and remain more prominent in the mix when multiple microphones are active. |
| Mute | Enable/Disable | The mute mutes/unmutes the corresponding automixer input. |
| Reset to default | Not Available | Sets weight of all each mapped microphone to 0. |
| Master | -90 – 0 dB | The master slider sets the automixer output level. |
| Master Mute | Enable/Disable | The master mute mutes/unmutes the automixer output. |
Advanced Settings
| Parameter Name | Parameter Range | Parameter Definition |
| RMS Attack | 2 - 1000ms (5ms by default) | The RMS attack time defines how quickly the automixer responds to an increase in a microphone’s input signal, determining how fast the channel becomes active when someone starts speaking. |
| RMS Decay | 2 - 1000ms (400ms by default) | The RMS decay time controls how slowly the automixer reduces the gain of a microphone after the input signal falls below the threshold, preventing abrupt dropouts at the end of speech. |
| Mixer Smoothing | 2 - 1000ms (10ms by default) | Mixer smoothing determines how gradually gain changes are applied to the output mix, helping to avoid rapid level fluctuations and ensuring a more natural, consistent sound when microphones activate or deactivate. |
Applications of Shared Mode
Gain sharing automixers are ideal for environments where multiple microphones are used simultaneously and speech dynamics are unpredictable. Typical applications include:
- Conference rooms and boardrooms – for seamless voice level control without operator intervention.
- Panel discussions and seminars – to ensure consistent clarity as different speakers take turns.
- Courtrooms and council chambers – where unattended, automatic microphone management is essential.
- Broadcast studios and talk shows – to balance overlapping dialogue naturally.
- Lecture halls and classrooms – for prioritizing instructor speech and reducing ambient pickup.
- Small theatre productions – to manage actors’ wireless microphones while preventing feedback.
Gain sharing provides transparent, real-time control that improves intelligibility and maintains a clean audio mix in multi-mic setups.
