## Detailed Description

```cpp
struct vx_req_aux_get_mic_level;
```

This method returns the master microphone (capture) level of the Vivox SDK sound system.

**See**: [vx\_resp\_aux\_get\_mic\_level](./structvx__resp__aux__get__mic__level.md)

This is a non-negative integer value between 0 and 100 (inclusive). The scale is logarithmic, which means that a level increase of 6 represents a doubling in energy, and a level increase of 20 represents a ten-fold increase in energy. The default value is 50.

### variable base

```cpp
vx_req_base_t base;
```

The common properties for all requests.

### variable account\_handle

```cpp
VX_HANDLE account_handle;
```

An optional parameter that specifies the account handle of the user whose microphone level will be retrieved.

This must either be unset or the account\_handle that was passed in to a [vx\_req\_account\_anonymous\_login](./structvx__req__account__anonymous__login.md) request that previously succeeded. If unset, the default account\_handle is used.
