"amplification" gfloat : Read / Write "clipping-method" GstAudioPanoramaClippingMethod : Read / Write
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. <title>Example launch line</title>

"amplification" property"amplification" gfloat : Read / Write
Factor of amplification.
Allowed values: >= 0
Default value: 1
"clipping-method" property"clipping-method" GstAudioPanoramaClippingMethod : Read / Write
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.
Default value: Normal clipping (default)
