Description
-----------

A limiter is similar to a compressor, but it's less flexible and designed to disallow sound going over a given dB threshold. Adding one in the Master bus is always recommended to reduce the effects of clipping.

Soft clipping starts to reduce the peaks a little below the threshold level and progressively increases its effect as the input level increases such that the threshold is never exceeded.

Property Descriptions

+-----------+-----------------------+
| *Setter*  | set_ceiling_db(value) |
+-----------+-----------------------+
| *Getter*  | get_ceiling_db()      |
+-----------+-----------------------+

The waveform's maximum allowed value, in decibels. Value can range from -20 to -0.1.
