# SetShapeFiltVolFrequency

> SetShapeFiltVolFrequency

Sets the corner frequency of a FLTVOL context.

## Syntax

```cpp theme={null}
HRESULT SetShapeFiltVolFrequency(  
         SHAPE_FILTVOL_CONTEXT* context,  
         float frequency  
)  
```

### Parameters

*context*   \_Inout\_\
Type: [SHAPE\_FILTVOL\_CONTEXT](https://docs.xbox.com/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context.md)\*

Pointer to a [SHAPE\_FILTVOL\_CONTEXT](https://docs.xbox.com/reference/audio/shapefiltvolcontext/structs/shape_filtvol_context.md) object.

*frequency*   \
Type: float

The corner frequency. Must be in the range 0-7999 Hz.

### Return value

Type: HRESULT

HRESULT success or error code.

## Remarks

The Filter/Volume (FLTVOL) block is implemented as a Chamberlin filter. To get the current corner frequency, use [GetShapeFiltVolFrequency](https://docs.xbox.com/reference/audio/shapefiltvolcontext/functions/getshapefiltvolfrequency.md).

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

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

## Requirements

**Header:** shapefiltvolcontext.h

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