This is an application that connect the microphone of your phone to headphone or external speaker. It allowed to speak in realtime, with low latency, no delay or lag, like a professional microphone. You will hear your amazing voice instantly. You can also record your voice in high quality.

How it Works:

User should connect the phone to wired headphone or external speaker for this application to work. Because the speaker of the phone doesn't have big volume. Using wireless connection (Bluetooth, Chromecast, TV) will add more delay to the mic. If wireless sound is mute, increase the frame_per_buffer until the sound is stable. It could be 48000 Hz - 5760, 48000Hz - 7680 depend on your phone. The bigger frame_per_buffer (second parameter), the more delay it is.


Below are some common usecase.

  • Sing karaoke with music in your phone.
  • Giving speech in front of people (for example inside an office) like a professional microphone.


This application works best from android 6.0 up, if it is possible, please upgrade your Android's versions.
