R makes an interesting point about a lower male voice sometimes getting nasally when over-compressed I'm going to have to play with that one. 6db of gain reduction on the peaks is also helpful to stop pumping before it starts. Using a modest ratio, then lowering the threshold while viewing the gain reduction meter to achieve apx. For some reason, every compressor I've ever seen comes with like a 30 or 50ms release as its default setting - not very useable at the defaults! Please note the 500ms release I recommended as a starting point - that's half a second. R points out the role of fast release times in pumping. The pumping that you refer to is often caused by high compression ratio and a fairly fast release rate. It can also be overused and can result very easily in the pumping sound that you mentioned. Once you understand compression well it is a great tool to use creatively.Ī compressor is one of those tools that most people use for keeping volume under control. So a blass guitar for instance or a bass drum can be compressed very heavily to control the volume without a big change in the sound, whereas the same compression on a vocalist could dramatically affect the sound of the voice. If you are trying to control sounds individually, such as in different tracks of a musical performance, the less frequencies in the sound, the more compression you can use without changing the sound. The pumping that you refer to is often caused by high compression ratio and a fairly fast release rate, so again with bass, it gets compressed down quickly if there is a high attack rate, but as soon as the overall volume level changes, the fast release rate allows the bass frequencies to assume the higher point and you get the pumping effect as this is constantly repeated. So a heavily compressed male voice may start to sound quite nasally as the bass frequencies become squashed. The result is not just a levelling of the volume but also a changing of the tone. If the bass frequencies for example are offering the loudest peaks, when you start applying lots of compression, the mid and high frequencies start to become more noticeable as the loudest sound, the bass, gets compressed more. The problem with using too much compression is that with complex sounds full of lots of different frequencies, they are all at different levels. There are many ways to use compassion and it can be a very subtle tool when used properly. Which means the quieter parts can be heard against background, or against music, or against environmental noise in the listening environment.Ī compressor is one of those tools that most people use for keeping volume under control, but very often without really understanding how it works or what it is doing to the signal. This is how a compressor benefits: Narrowing the dynamic range so gain can be increased without overmodulating. So, for example, an input peak at -3db, with a ratio of 3:1, and a threshold of -6db, that peak is going to reduced to -5db, allowing the overall volume to be increased via the gain control, bringing up the quieter parts by several db. These settings take a little dynamic range off the top - that is, above the threshold, output volume increases not at 1:1 with input volume, but at the ratio you set. Be aware of any harshness introduced by aggressive settings of ratio or threshold. If you set a ratio of somewhere between 2.5:1 and 3.5:1, an attack of 30ms, a release of 500ms, and bring down the threshold until the gain reduction meter is showing say, -6db on the volume peaks, you're in a ballpark to start tweaking to ear. (You can use Sony's "Auto Gain Compensation" instead of touching output gain) Ratio (sometimes called "amount" in sony-speak) There are many of the same controls in the track compressor as you find in SawStudio levelizer.
