Class for Limiter Stage Limiter is a single band compressor at the end of the processing chain, commonly used to protect the signal from overloading and distortion. Limiters have multiple controllable parameters: enabled/disabled, linkGroup, attackTime, releaseTime, ratio, threshold, and postGain.
Limiters can be linked in groups across multiple channels. Linked limiters will trigger the same limiting if any of the linked limiters starts compressing.

DynamicsProcessing.Limiter!: copy constructor |
Public methods
getAttackTime
fun getAttackTime(): Float
gets attack time for limiter compressor in milliseconds (ms)
| Return | |
|---|---|
Float |
attack time for limiter compressor in milliseconds (ms) |
getLinkGroup
fun getLinkGroup(): Int
Gets the linkGroup index for this Limiter Stage. Only limiters that share the same linkGroup index will react together.
| Return | |
|---|---|
Int |
linkGroup index. |
getPostGain
fun getPostGain(): Float
gets the gain applied to the signal AFTER limiting. Measured in decibels (dB) where 0 dB means no level change
| Return | |
|---|---|
Float |
postGain value in decibels (dB) |
getRatio
fun getRatio(): Float
gets the limiter compressor ratio (N:1)
| Return | |
|---|---|
Float |
limiter compressor ratio (N:1) |
getReleaseTime
fun getReleaseTime(): Float
gets release time for limiter compressor in milliseconds (ms)
| Return | |
|---|---|
Float |
release time for limiter compressor in milliseconds (ms) |
getThreshold
fun getThreshold(): Float
gets the limiter compressor threshold measured in decibels (dB) from 0 dB Full Scale (dBFS). Thresholds are negative. A threshold of 0 dB means no limiting will take place.
| Return | |
|---|---|
Float |
limiter compressor threshold in decibels (dB) |

| Parameters | |
|---|---|
linkGroup |
Int: desired linkGroup index |
setPostGain
fun setPostGain(postGain: Float): Unit
