I am noticing 2 schools of thought in compression usage in a mix (Each camp appears to think the other camp is completely incorrect.)....
- Compression is the final "glue" of the mix to be adding extremely lightly only to the bus channel at ratios no higher than 2:1 at a very quick attack. The fader should be the only general level setting device.
- Compression should be added to help the signal sustain a smooth regular level of signal and should be added in layers at the track, bus, and perhaps even master output stage in varying attacks and ratios as to avoid pumping and maximize audibility.
Which school of thought are you and why? Do you have a different approach all together?
