Compressor

Compressor control the overall amplitude of a signal by reducing that part of the signal which exceeds an adjustable level (threshold) se by the user. When the signal exceeds the threshold level, the overall amplitude is reduced by a ratio, also usually adjustable by the user. For example, if the ratio of compression is set for 2:1, any part of the signal exceeding the threshold level is reduced by one-half. Compressor are used for reducing the overall dynamic range between the loudest and quietest signals. Compressor has ratio settings that are typically anything above 1:1 up to 10:1
