Description

Example launch line

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.

Property Details

The "amplification" property

  "amplification"            gfloat                : Read / Write

Factor of amplification.

Allowed values: >= 0

Default value: 1


The "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)
