Upwards Compression?

[orange]

With the scriptnode, how can we achieve this?

• If the signal is below the threshold value (in dB) >> Multiply the signal with a ratio value

• If the signal is above the threshold value >> Do nothing

Similar to the classic (Downwards) Compressor with an opposite dynamic range way. This is Upwards Compressor which process the below threshold values.

@orange I think I can use a gate to process the below threshold signal.

@orange Looks like you want something like an expander or transient designer? I achieved similar things with the envelope follower.

Hey @orange did you achieve the result that you wanted? I am currently looking for something that comes close to OTT type compression. I have no problems to deal with the downward compression but have not found an intuitive way to create an upward compressor in HISE yet - the goal will be to combine downward and upward compression. :)

@Straticah
Frankly, I did not continue this project. But if someone has a solution for this, it would be good to know.

@Straticah You might want to try something from Faust like si.bus(N) : peak_expansion_gain_N_chan_db

I think I have implemented something similar for an OTT but it was a while ago. If I find it I can let you know.

@HISEnberg how did you make the ott?

[Lindon]

@mmprod you have the scriptnode updown_comp for this sort of thing now...

@Lindon aha thanks
