Summary:An audio compressor using a P-channel junction field effect transistor (JFET) as a voltage controlled resistor at the input of an integrated circuit operational amplifier. Good frequency response and fast attack are provided since the gain control element is not a part of the biasing circuit with limitations due to settling time thereby avoided.
