What is a Voice Modulator and How Does It Work

A voice modulator can be a physical device or a voice changer program, which aims to modify the tone, timbre and other elements of the human voice. This in order to change how it sounds or even add special effects that help give it the required focus, for example, more emotional, intense, deep, sensual, etc.

The workflow of voice modulation is very simple. The first thing to do is capture the audio with a microphone, preferably a high fidelity one. Once the voice is obtained, it is decoded by the program to allow us to manage different parameters. This is because there are different variables that can be modified by the online voice modulator.

By modifying the tone, volume, bass, high or medium, timbre, echo, intensity or distortion it is possible to achieve certain effects. By playing with these parameters, you can achieve useful effects for live streaming on streaming platforms and video creation.

What Types of Voice Modulators Have

There are several types of voice modulators. And currently, almost all the available programs leverage AI technology to achieve better results of voice modulation. Below, let's explore them one by one.

  • Online voice modulator: As its name indicates, the online voice modulator works directly on the Internet. Its use is simple, since you only have to upload the audio and modify its parameters to then download the already modified voice.
  • Voice modulator for PC/Mac: It is a program to change the voice that is installed directly on the computer. Compared with the online voice modulator, the PC voice modulator has more complete functions, greater range of parameters, effects and quality.
  • Voice call modulator: Available as both a device and software, the voice call Modulator is used to change your voice only during phone or online calls. It can be used both to hide the person's identity and to add fun effects.
  • Real-time voice modulator (for streaming): Lastly is the real-time voice modulator, which is designed to add effects to your voice while you are streaming live. It works perfectly on streaming video platforms, such as YouTube, Discord, Twitch, OBS, Skype, among others.

How to Choose the Best Voice Modulator

To choose the best voice modulator, take these tips into account:

  • What it is used for. An audio editor is picked if you only want to edit voice recordings. An AI voice changer is better for voice modulation and cloning for voice overs, speeches, calls, live streams.
  • Customization. Consider whether you can only use default effects or modify the parameters in a custom way.
  • Type. It is important to consider whether the voice modulator works online or if you have to download and install a program.
  • Performance. Check whether the voice editing results are realistic and of good definition or appear artificial.
  • Compatibility. Make sure whether it can be worked for streaming, video game or chat platforms, as well as audio formats.
  • Price. Free voice modulator is preferred. But, some programs only offers time-limited free trial or require you to upgrade to paid plan for unblocking advanced features.
