A lookahead compressor/limiter that's soft as a lamb.
There is also a version with a Rust GUI, latency compensation and proper scaling of the parameters: https://github.com/magnetophon/lamb-rs
Lamb was made with these goals in mind:
- Be as clean as possible
- Give the user full control over the character with the minimum amount of knobs.
The secret sauce is all in the attack/release:
you can change both the length and the shape of their curve.
The shapes look like this; c0 in Desmos corresponds to the shape parameter in the plugin.
When it is at value 0, the curve is a slice of pure sine.
The release hold parameter prevents the gain reduction from coming back up if it needs to go down again soon.
You control how soon is soon with release hold.
This adds latency though.
ATTENTION If you want to use the plugin with a samplerate of more than 48k, make sure you change
MaxSampleRate at the start of lamb.dsp.
There's a couple of other user preferences as well, documented in the dsp file.
This algorithm needs double precision to function. You can build it with any of the faust build scripts, for example:
faust2jack -double -time -t 0 lamb.dsp
Or:
faust2jaqt -double -time -t 0 lamb.dsp
