# Gain

The gain operator is simple yet very useful, as it includes a gain (or **volume**) control. It also supports modifying the content of the stereo channels (channel mapping)

:::(Info) (Note)
This operator displays the audio **input level** before processing and the **output level** after the operator has been applied, allowing you to monitor how the adjustments affect the signal.

A miniature audio meter (VU meter) in the header indicates incoming audio, so you can quickly verify that the operator is receiving audio even when it is collapsed.
:::

**Gain**

* **Lock left/right gain** - If enabled, gain adjustments will be applied to both left and right channel.
* **Left gain (dB)** - Amount of gain (-48 to +48 dB).
* **Right gain (db)** - Amount of gain (-48 to +48 dB).

**Channel mapping**

* **Left channel** - Content of the left audio channel
* **Right channel** - Content of the right audio channel

**Warnings**
* **Signal overload** - If the peak level is above 0dBFS, the signal overload indicator will be active for two seconds.
* **Peak Overload (dB)** - last measured peak value in dBFS.

:::(Info) (Tip)
Use [Settings](/docs/settings-audio) to adjust how long the signal overload indicator stays active, and [Project Options](/docs/runtime-performance) to change the maximum peak level displayed in all audio meters to your preference.

(The operator is available in Composer R1 2025 and later releases)
