Types Of CompressorsĬompressors come in both hardware and software. If you are familiar and confident with the compressor you have, then you may skip the following portion. The type and brand of compressor is important in understanding compressor ratios so you have to make sure you have the proper and fitting compressor unit since it will help you produce the best audio output depending on your goal. You may ask, “Aren’t all compressors the same?” The answer is no. Upward compression is when you increase the loudness of the quiet sounds below a threshold but still keeping the louder sounds in their original state.Ĭompression ratios are usually expressed in the unit of decibel (dB) and there are different kinds of ratios to choose from based on the kind and brand of compressor to be used.Downward compression is when you lessen louder sounds over a threshold while keeping the quiet sounds in their original state.Here are the two ways you can use a compression ratio: Simply speaking, through compression ratio, you can reduce the volume of sounds which are louder than other parts of a certain track or increase the quiet sounds of your audio output by compressing the audio signal’s dynamic scope. You will be able to control the compression ratio through the ratio knob on the compressor unit itself. When the input signals exceed the threshold, the compressor will start to work on it and let signals pass through depending on the compression ratio which was set by the user. A compression ratio is the ratio which determines the amount of compression or attenuation that is to be applied to a signal entered into the compressor in order for the same to rise above the set threshold in sound recording or similar activities.
