Adds a soft-clip limiter audio effect to an audio bus.
A "limiter" is an audio effect designed to stop audio signals from exceeding a specified volume threshold level, and usually works by decreasing the volume or soft-clipping the audio. Adding one in the Master bus is always recommended to prevent clipping when the volume goes above 0 dB. Soft clipping starts to decrease the peaks a little below the volume threshold level and progressively increases its effect as the input volume increases such that the threshold level is never exceeded. If hard clipping is desired, consider [constant AudioEffectDistortion.MODE_CLIP].

- The waveform's maximum allowed value, in dB. Value can range from -20 to -0.1.
- Modifies the volume of the limited waves, in dB. Value can range from 0 to 6.
- This property has no effect on the audio. Use [AudioEffectHardLimiter] instead, as this Limiter effect is deprecated.
- The volume threshold level from which the limiter begins to be active, in dB. Value can range from -30 to 0.
