Microphone Pro

This application will 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 mike. You will hear your amazing voice instantly. You can also record your voice in high quality.

User should connect the phone to wired headphone or external speaker for this application to work. Because the speaker of the phone has limited volume and is placed too close to the mic which will cause not good loopback sound.

Sound effects are only supported in phones which run android 6.0 up.

The delay is device dependent, if the app doesn't produce sound on your phone, please turn on the auto adjustment feature in the menu, or read through some of our tips. You can check out the liter, less delay version in the link below:

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 usecases.
