Anti "pop" noise circuit for amplifiers

The proposed circuit is simple, even to beginners in electronics. Amplifiers are usually susceptible to pop noises during turn ON or turn OFF. This noise is usually caused by the charging of the power supply capacitors. Ones power is shut in, the capacitors amplitude rises per time which generates fast rising transients which is instantly picked up by the amplifier and is thus, amplified and this give rise to the "pop" noise. In order to combat this parasitic noise, the designer need to subtract the charging time of the capacitor from the the time taking to provide power to the supply through the switch, the remaining time becomes the time taken to provide power to the amplifier board. To achieve this, one need to design a delay circuit that can hinder the transfer of power to the amplifier board until the power supply capacitors get fully charged, and that is the function of the circuit above. When the switch is pressed, the amplitude of the capacitor potential rises with respect to time which is determined by the RC tank at the base of the PNP transistor. The time constant can be calculated with the formula=> t=RC. In the circuit above, t=3.3sec. So when powered ON the amplifiers power supply capacitors get charged within 2-3sec, once it is 3.3sec, the circuit above will connect the amplifier board to the supply, or the speaker to the amplifier board, it depends on where you chose to place the circuit in your design. In my design, the circuit is placed in series between the amplifier board supply pin and its power supply. The transistor must be rated at voltage greater than the supply, the 330R resistor could be 1/2W for safety, the relay could be 12v,400R.
