The app lets you can create various conversation environments for voice chat in instant messenger programs, or to make fun voice calls with PC-to-Phone apps. You can also play around with audio tracks create remixes of your favourite songs, etc.
AV Voice Changer Software has a number of good options to choose from. So if you need a voice changer, equalizer, or recorder, AV Voice Changer has something that covers it. The app is fairly fast and stable, and you should experience no lag or crashes.
It also has some advanced features such as audio capture. In addition to recording audio from your microphone, the app also allows you to use sounds generated by other apps as the audio input source, this can be very useful if you want to edit and augment preexisting music tracks, for example.
The downside to AV Voice Changer Software is that the interface look dated, and the learning curve is quite steep. This fact is cemented by the confusing layout, which is counter intuitive. That being said, if you get past the layout and don't mind spending some time getting to grips with the app, then its OK. However, there are other apps available that are easier to use.
