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