How does a voice changer circuit work?

The system consists basically of a digital voice modulator and an audio amplifier, developed around respectively the chip IC1 (HT8950A) and IC2 (LM386I) the user’s voice is captured by an electret microphone (MIC1) and reproduced normally or frequency offset in a dynamic speaker (SPK1).

Is a voice changer legal?

ARE VOICE CHANGERS ILLEGAL? Audio processors that modify the tone and format of voice using effects are legal and can generally be used everywhere. However, making use of a voice changer to commit crimes or engage in other harmful behavior is NOT legal.

How does a voice modulator work?

The voice modulator changes the pitch of voice inputs. Users speak or sing into a microphone while playing keys on a keyboard. The modulator outputs frequency-shifted copies of the voice data to match the notes selected from the keyboard while preserving vocal formants as much as possible.

Is Voicemod real?

Voicemod adds real-time voice changing and custom sound effects to tons of games and programs including CS:GO, Minecraft, World of Warcraft, Rust, Fortnite, Valorant, League of Legends, Among Us, Roll20, Discord, Skype, WhatsApp Desktop, TeamSpeak, and more!

How do you modulate your voice?

Let’s find out:

1. Be Loud and Clear. Being loud does’t mean that you have to shout.
2. Practise Variation. You can look up for some steps that you can practise in order to develop the desired voice.
3. Stress on Powerful Words.
4. Create a Crowd Pleasing Speech.
5. Effective Pauses.
6. Avoid Ahs and Uhms.
7. Sound Enthusiastic and Confident.

How does a digital voice changer circuit work?

The frequency of the latter, which is about 512Khz, is determined by R2.After digitized voice signal is stored in a static RAM (SRAM), also controlled by the time base generator, a control circuit extracts information from the RAM and transferred to a latching register.

How can I make a balanced voice changer?

Its output contains sum and difference frequencies only, which it achieves by multiplying the audio with a fixed frequency carrier. A balanced modulator can be built in several ways. You can use an IC such as the old LM1496 which was designed for this purpose. Or, you could use a multiplier IC, such as the AD633.

How does IC2 work in a voice changer?

The Q output of IC2 is the control signal for the analog switch, so it’s the “carrier” that modulates the audio by turning the switch on and off. The modulated audio from IC5 goes to power-amp IC6 via potentiometer R7, the volume control. Note that R7 is also referenced to audio ground.

How to make a voice changer with a transformer?

Since R D « R L, we have Vout » (R D / R S) x Vin » zero. This circuit effectively multiplies the voice signal by a unipolar square wave (switches between +I and 0): half the time Vout » Vin; and half the time Vout » 0. Figure 3 is easier to build than Figure 2, but it still requires a transformer.
