Amplifies an audio stream by a given factor and allows the selection of different clipping modes. The difference between the clipping modes is best evaluated by testing.

“amplification”
property“amplification” gfloat
Factor of amplification.
Flags: Read / Write
Default value: 1
“clipping-method”
property “clipping-method” GstAudioPanoramaClippingMethod
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)
