@ -159,6 +160,19 @@ parameters:
|
|||
|
||||
bands work as they do in `threebandeq`. the width parameters control how wide an audio signal should be in the stereo field. `width` of 1 leaves the audio as is, `width` of 0 makes it mono, values between 0 and 1 decrease the stereo width, values over 1 increase it.
|
||||
|
||||
### tritu
|
||||
|
||||
hard limiter followed by a soft limiter with distortion
|
||||
|
||||
parameters:
|
||||
- `pregain`: pregain for the hard limiter
|
||||
- `drive`: drive for the soft limiter
|
||||
- `distortion`: amount of distortion on the soft limiter
|
||||
|
||||
distortion affects lower volumes more than higher volumes, so if you crank up `drive` a lot, there will be less distortion (this is a good thing for high values of `distortion`!). if you leave `drive` low and set `distortion` to max, your audio will turn to almost white noise
|
||||
|
||||
i like this plugin a lot

## contributing
|
||||
|
||||
issues and prs are welcome, but please open an issue before making any big pr, i don't wanna have to reject a pr where you have put a lot of effort on
