In fact, there are not so many open-source voice changer apps right now. However, Equalizer APO is one. This is seen as one of the leading and perhaps the best open-source voice changers available today. This remarkable system-wide equalizer has become the go-to option for Windows users, as it allows them to turn latency to zero in audio inputs.

Equalizer APO is a tool for the ages, as it has many great features, making it one of the favorites among users. Some of the said features are:

This voice changer for Discord allows users to change their voice in real-time and offers a vast array of voice filters. These features have made it the go-to option for advanced users and beginners alike, not only because of its almost unlimited number of voice filters but also because of its customization.

Besides that, you can create potential voice filters of your own by saving your customized ones. This sort of flexibility has made Equalizer APO the best open-source voice changer and virtual audio tool that you can find today.

As mentioned before, there are not many open-source voice changer apps for you to use currently. However, you can use some feasible and well-known free voice changers compatible with your computer and mobile phone instead.👇🏿

Voice Changer Windows Free

Windows users get their hands on many things, including gaming, chatting software, video calling, conferencing, etc. That's why it's imperative to find a free voice changer software that also happens to be open-sourced.

Moreover, it must work with online chat or help you use any audio effect you like during a voice recording or call. To make it easier for you, here are three of the best open-source voice changers on Windows:

The anonymous voice changer allows you to use any audio effect during a voice recording or whether you're using it as a real-time voice changer. While the tool is simple, it offers a little customization, which can help you morph your voice in any twisted way you like.

Voice Changer Android App

After talking about voice changers for Windows, let's talk about some of the best tools you can use for Android today, or in other words, open-source voice changer apps for Android. Now, you don't have to go to Google Play to find any of them, as we have compiled a list of two right here:

1. Voice Changer with Effects

Voice Changer with Effects is one of the leading tools on Android for changing voices. As a call voice changer, this app is not only easy to use but also offers a few hilarious voice effects, which is why it has been around for years.

Besides that, it's open source, so you can tweak it around all you like. Or, you can simply use one of the four filters, which includes aliens and zombies, to do a funny voice recording. That's what makes this the most famous voice changer on Android today.

Voice Changer with Effects


  • Various fun-inducing voice filters
  • Very easy to use
  • Ideal for beginners


  • Doesn't support live-voice morphing
  • The design is obsolete

2. Voice Changer - Audio Effects

Voice Changer - Audio Effects is a wonderful app. And as the name suggests, it allows you to change your voice during voice recording or change the background with sound effects. While it's ideal for voice recording only, it can also help you convert existing audio clips.

Therefore, this open-source tool isn't just for those who wish to record their voice in a different filter. It's also ideal for those who wish to convert their existing call or other audio recordings using funny and customizable voice effects.

Voice Changer - Audio Effects


  • Fun and easy to use
  • Ideal for quick uses
  • Records high-quality audio clips


  • Doesn't support live voice filtering
  • Too few voice filters

Open Source Voice Changer FAQs

Any of your further questions will be answered in this section:

1. What is the best completely free voice changer?

The best kind of voice changer is Voicemod, although it's not completely free. It allows you to do many things with the tool before you reach the free limit. On the other hand, you have Clownfish, which is totally free but doesn't have customization or filters like Voicemod.

2. Are voice changers illegal?

No, it's not. Unless a person changes their voice for fraudulent or illegal activities, it is not illegal or banned in any country. However, you should be careful as some people might use a voice changer to scam you.

3. What is better than Voicemod?

There are a few alternatives to Voicemod, but you can't call them better than Voicemod. The primary reason behind that is the ability of Voicemod isn't exactly dependent on its voice filters but also on customizability and user-friendliness.


These are some of the best open-source voice filters and changes that you can use in 2023. We explored a few great options, and perhaps Equalizer APO is the best open-source tool. However, it doesn't offer the same features as Voicemod or MorphVox Pro.

Then again, it dials down to the need of the users and how much they wish to use this voice changer. If you're a casual user or gamer, then using Voicemod is ideal. But, if you wish to go technical, then Equalizer APO is a good option.
