class SilenceFactory(fill_value=0)

Bases: Carrier

Generate silence

All channels require at least one continuous output. If no token is specified for the continuous output, silence is used.

Notes

The fill_value can be set to a number other than zero for testing (e.g., to characterize the effect of a transformation).
