PUNEET SAMTANI Let’s talk Compression! Point of compression in your mix. Earlier compression was used as a way to protect electronic equipment and tape from overloading. With the changing recording and listening mediums, the application of the compressor has evolved as well. Sound is very dynamic. A singer, a snare drum, violin, acoustic guitar can go from very quiet to blasting loud within a second. Before compressors came into the picture, an engineer had to ride volume faders to control the signal level before it went onto tape every instance. The compressor can look at an audio signal coming in and can determine if it is at an acceptable level. If it’s too loud it can turn the signal down and if it’s too low, it can turn It up. By setting a slow attack, you can make the quiet parts of the tracks loud while containing the louder parts of the track without killing the transient, thus instilling instant energy and excitement to the tracks. You can adjust the sustain of a sound and create an illusion. This is great for snare drums and bass guitar. 42 The Score Magazine highonscore.com Compressors have a certain sonic characteristic that impart a certain frequency response to the audio. They can be considered as tone machines as well. All compressors have the same settings. Why we chose one make over the other is because if gives us different tonal quality. A vocal track going through 2 different compressors having exactly the same settings are bound to sound different for this reason. Types of Compression. There are 2 types of compression broadly. Upward compression and downward compression. Downward compression maintains the level of the quiet sounds and reduces loud sounds which are over a certain threshold. A limiter is a type of downward compression. Upward compression leaves louder sounds unaffected and makes the soft sounds louder which fall below the threshold. Both these methods of compression end up reducing the dynamic range of the signal.
