Voice Changer Mic: Cosplay - use lapel MicSpeaker is a free multimedia application developed by StereoMatch for Android users. The app enables users to use their Android device as a real-time voice changing microphone for cosplay purposes. It can be used with other devices such as PC, PS4, Xbox, external speaker, or another phone. However, it cannot be used with apps running on the same device such as Discord, Skype, or game apps. The app comes with a high-quality 14-voice voice changer that can run in the background, even with the screen off.

The app can also be used as a low-cost low-latency noise gate filter to remove low volume breathing sounds from live podcasting/broadcasting with or without voice changing. Some voices benefit from noise gate as well, such as Venomous and Exterminator. The app can be used with gaming headsets with detachable mics, plugged into the AUX port of the Android device. The app provides detailed instructions, diagrams, and suggestions for Y-splitters, mics, and speakers for cosplay. Clicking the contact button provides users with help via email.
