Compressor with Negative Ratio

[VibraSound]

The way I see this :

Positive Ratio
- Natural Compression/Limiting

Negative Ratio
- Creative over the top Limiting.
- To cancel out very loud signals.
- Can be use for a pumping/shaping effect.
- Nice for fixing a bad inconsistent track or mix.
- Combine this with fast attack times, and you will be able to create completely new signal envelopes.
- Can be use like a Leveler for Radio station
(Levelers work especially well with vocals, as there are huge dynamic differences in the human voice)
- DeEsser to reduce or eliminate excess sibilant sounds.
- Cool effect for extreme sidechain compression.
- Heavy pumping, backward (reverse) sounds, etc.
- Perfect for very cool compression effects.
- Negative compression is the sound of Daft Punk.
- And more ...


The dbx® 160A's unique "INFINITY +" inverse-compression mode actually decreases the audio output level below unity gain when the input exceeds threshold, a real lifesaver for correcting overbearing vocal choruses and controlling runaway house mix levels.
A detector input can be used with an equalizer for de-essing sibilant vocals and selectively smoothing out boomy notes on acoustic guitar and bass.

Let's make a big list of all the Negative Ratio Compressor
just like the Waves C1.

- Ratio 1:1 to 50:1 (compression), 0.5:1 to 1:1 (expansion)
- Cancellation Mode -50:1 to -5:1 to cancel out very loud signals

Right now I have found :

Cockos ReaComp features upward compression.

all three of them support negative ratio. and lllooooaads more.

I agree on that. I have a snare track that a less than stellar drummer played and the dynamics are so inconsistent but some experimentation with negative ratios fixes it better than any positive ratio did. Regards.

Wait a minute, negative compression ratios and upwards compression are 2 different things aren't they ?

Upwards compression is essentially expansion , and negative compression is for squashing stuff.

Compassion does both.

Red Phatt Pro by Jeroen Breebaart is awesome !
Too bad it's discontinued, so this post is pointless to you, but i couldn't help mentioning.
I hope it will be ported to a Tone Boosters version soon ...

Upwards compression isn't the same as expansion, otherwise it wouldn't be called compression

Upwards compression squashes the dynamics by making the quieter parts (below the threshold) louder, "normal" downwards compression by making the louder parts (above the threshold) quieter.

Expansion, on the other hand, gives you more dynamic range by making the quiet sections even quieter, and/or loud sections even louder.

Sorry for my shameless self promotion, but Q796 does both negative ratio and upward compression.
Yes, they are completely different things

image line maximus and the cakewalk fx dynamics processor (comes free with sonar): you can draw the curve as you like

cheers, akj

Yeah true, this shows it better

Could never get upward compression to work with compassion, try as i might, and i believe it's the only 64 bit one that can do it.. did that ever get fixed, my demo expired ages ago

Upwards Compression always worked here - 32 bit AU...
It does depend on the values of Curve Law and Release Type being above 50% or 0% respectively though (which kind of makes sense).
