You’ll also come across terms like upward compression and expansion, both of which flip standard compression on its head. A limiter is essentially just a compressor set at a high ratio - ie, the amount of compression applied above the threshold - so that it completely cuts off all peaks over a certain level. We’ve included some plugins labelled as limiters below, too. The former tackles the whole frequency range at once, while the latter can be applied to low, high or mid range frequencies independently. Then there are broadband or multiband compressors. Transparent compressors aim to do their job without you noticing they’re there, controlling dynamics but remaining as faithful as possible to the input audio.Ĭharacterful compressors, which are often emulations of vintage hardware, may alter the sound of your audio slightly, usually through subtle EQ or filtering, or by adding a touch of musically-pleasing distortion.
It responds how I remember it.One of the main divides in compressor types are those described as transparent and those that are ‘characterful’. The Native instruments VC2A is probably my favourite version in a plugin. I used a hardware one constantly in 1990's when I was a studio recording engineer. I use this style of compressor as a leveller.
Great for bass, guitars, keys, and vocals (in conjunction with another compressor like an 1176 if you need to deal with a vocalist's transients). It leaves transients alone and averages out the signal over time. Gain would make the panel inside brighter optically and then you adjust the peak to control the amount of compression (how much of the light the photo cell responds to). You control it by using the input gain and peak together. It worked using a luminescent panel as an input and photocells 'seeing' and adapting the compression ration and release, if the photo cell sees light it continues to work. If it was modelled properly then the attack/release and the ratio are dependent on the source signal but generally the original Teletronix was a 10ms attack time, a 4:1 ratio and the release was around 60ms on quick signals with a further hold from 1s - 15s depending on the signal.
