Surely on more than one occasion you have wanted to amplify your voice through a megaphone in a meeting or presentation and not let your throat screaming, because we bring you the solution in a small guide in which we teach you
how to use the smartphone as a megaphone
As you can imagine, in addition to the smartphone, it
is convenient to have an external speaker that amplifies the sound
. For this task, we could use some Bluetooth speakers, but knowing that this type of connectivity can present some type of lag or delay in the response time. The ideal is to place the wireless speaker near the listeners, so that they receive our speech clearly.
How to use the smartphone as a megaphone.
First of all, what we are going to do is make sure we have a WiFi connection to access the Play Store and download an
Android microphone application
. There are many, some will be better and others worse, but the ones I have tried, the ones that have given me the best result are:
Microphone by Wonder Grace
and
Microfone by Terens
.
Personally I prefer the
Microphone
application
of Wonder Grace
, since it is more complete and gave me better feelings in the response times. The goal is to
use the smartphone as a microphone and the external speaker as an amplifier
.
Once the microphone application is installed in our mobile, we just have to execute it and in the case of Wonder Grace's Microphone, we click on the drawing of the microphone to start capturing the sound through the microphone of the phone.
We must bear in mind that the program will ask us to have a loudspeaker connected, it
recommends that it be through the 3.5mm jack since if we use Bluetooth connectivity there will be a large lag and there will be an echo effect
. If we use the 3.5mm jack, the phase shift is much smaller, but there are still a few milliseconds of delay.
It is not the most perfect megaphone solution, but it is a clear example of how our smartphone can take us out of a hurry using it as a megaphone.
