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)
