This is done with pitch control, or autotune, and will like you modify the voice by a number of octaves. With the diode switches closed, a very low resistance (RD) is in parallel with RL. (I’ve learned the hard way that such protection is a good idea.) With respect to audio ground, actual ground looks like a negative voltage. NV. You can use a better op-amp (e.g., LF411) if you have them. I’ve been a fan ever since. The app… How can we do that? But if that’s not you, then get the Online Only Edition and save a few trees and some cash. TP2 allows you to look at the signal going into the power-amp. Copy the URL of this page to share your creation! The modulated audio from IC5 goes to power-amp IC6 via potentiometer R7, the volume control. Since an electret mic produces a relatively large signal, IC4 is configured for unity gain. To use an unregulated wall-mount supply, you could use the circuit described in my upcoming article on switching regulators. Some interesting effects are produced by inserting a resonant peak into the middle of the audio spectrum. Note that the carrier current is a bipolar square wave (switches between +I and -I); you want those diodes to open and close quickly and cleanly. Voice Changer: will activate/deactivate the voice effects. Temporarily Bypass Voice Change Effect. You … C7 is required since the input of IC6, an LM380, is referenced to actual ground. Start the preparation right now and have fun this winter. The input goes through a voltage divider formed by resistor R1 and rd, the dynamic resistance of the diode. Referring to Figure 2, if point X is positive with respect to point Y, diodes D1 and D2 conduct and connect points A to A’ and B to B’, thus allowing the input to flow to the output.
