## Functions

## Types and Values

### struct GstAudioAmplify

    struct GstAudioAmplify;

## Property Details

### The `“amplification”` property

      “amplification”            gfloat

Factor of amplification.

Flags: Read / Write

Default value: 1

### The `“clipping-method”` property

      “clipping-method”          GstAudioAmplifyClippingMethod

Clipping method: clip mode set values higher than the maximum to the maximum. The wrap-negative mode pushes those values back from the opposite side, wrap-positive pushes them back from the same side.

Flags: Read / Write

Default value: Normal clipping (default)
