| is compression accumulative? i.e. if u compress tracks in ur mix the compress on ur master do they add up ? |

| er, no they just mean you have compressed the sound more. They are compressed on the track then further compressed on the master. Think of it as adding rather than multiplying. |

i'm pretty sure compression is multiplicative. you have a 10:1 ratio on one compressor and then a 5:1 on another you are compressing 50:1 in the end. I can't find a link to prove it but i'm quit sure i read that in one of my mixing books. |

I must support this opinion, I was always taught so also... |

Interesting question.
Ultimately, I think the answer really depends on the settings (esp. threshold, ratio, attack, and output) of each successive compressor. Think about it - if you squash your signal once with a low threshold and high ratio, there likely won't be anything left to compress at the next stage. So say, for example, your initial compression ratio was 25:1 and your threshold was -20dB (for simplicity, let's say a quick attack & no additional output gain). Then, at the next stage your threshold is -5dB and a ratio of 10:1 - the already-compressed signal coming through the second compressor would be below the threshold, so no additional compression would occur. Therefore, the compression would not be multiplied (i.e., 250:1) nor added (i.e., 35:1).
Now, under the opposite conditions (light compression followed by heavy compression), it would seem to me that the total compression would simply be the one that is compressing the signal the most. In other words, the total compression is equal to the maximum compression, rather than summing/multiplying. But, I'm just guessing and I'm thinking in terms of chopping off transients (which is what the ratio is really determining), rather than the overall effect on loudness, which is more related to output at each stage - I guess I've never really thought about it that much. :conf:

I know what you mean, but the ratio isn't the only factor even if it is the amount of the compression applied. It would be the initial compression then that amount of compression is then compressed by the second compressor but I don't think that accurately represents the situation because of the other variables. Also, they work discretely and not in tandem (unless triggered) so in some ways you are adding extra compression (especially in the case completely different compression settings as per cryos post) as they are serving different purposes.
If your adding two of the exact same compressors then yes, you would just be multiplying but I can't really thing why you would do that. |
