Mymic – Mobile application as a replacement of wireless microphones using UDP over wifi

Abstract

Nowadays, most of event halls are prepared with normal wireless microphone system that depends mainly on FM radio frequencies. These systems have unexpected problems such as no enough microphones, interferences, weak signal, running out of battery life, unwanted noise, and feedback. Moreover, extra equipment is required if the speech needs recording. The proposed solution is “MyMic”. It is a mobile application developed by ALTARIQ Systems & Projects to solve the previous issues. The main idea of the application is using the smartphone connected to WiFi as a wireless mic. A control panel running on PC/Tablet (server) manages Mobiles (Clients); it receives the sound streams using UDP packets and sends processed sound stream to the sound system. The control panel allows multiple speakers simultaneously. System testing inside a hotel event hall was successful with clear sound of three simultaneous speaking users where noise values were 4.7 % in average.
