# GetShapeFiltVolFrequency

Gets the corner frequency of a FLTVOL context.

## Syntax

```cpp theme={null}
float GetShapeFiltVolFrequency(  
         const SHAPE_FILTVOL_CONTEXT* context  
)  
```

### Parameters

*context*   \_In\_\
Type: [SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context)\*

Pointer to a [SHAPE\_FILTVOL\_CONTEXT](/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context) object.

### Return value

Type: float

The corner frequency.

## Remarks

The Filter/Volume (FLTVOL) block is implemented as a Chamberlin filter. To change the corner frequency, use [SetShapeFiltVolFrequency](/reference/audio/shapefiltvolcontext/functions/setshapefiltvolfrequency).

The filtering behavior is designed to be identical to that in XAudio2.

For more information, see the [Filter/volume block (FLTVOL)](/build/console-features/audio/overviews/shape-overview#ID4EBH) section of [Overview of SHAPE](/build/console-features/audio/overviews/shape-overview).

## Requirements

**Header:** shapefiltvolcontext.h

**Supported platforms:** XBOX One family consoles and XBOX Series consoles
