This is for cameras and i can remove this red connector, okay that’s for the hot shoe and it has a cable. One. End has three connectors tip ring sleeve, and this has four tip ring ring sleeve and this one, which has four, has to go into the phone. So 3.5 millimeter connector goes there, so the other one is not used that has free and free, so that’s. For a camera such as this one sony alpha 6300, okay here’s, a smartphone which has a 3.5 millimeter headphone jack and microphone input. I have to remove that cover, otherwise i cannot connect it just plug in this four element: connector there and i have a hd audio recorder, so that’s the android application’s name, hd audio recorder. Okay, so it looks like this currently it’s recording the sound from this microphone and come here to the first icon, which looks like a microphone that one select microphone and earphones. If i unplug, even the icon disappears so plug it. In yes, turn off the radio and there’s the microphone sign tap on it, earphones so that’s the earphone out and microphone in select earphones, okay and now let’s record and it’s. Recording some sound since this one is a so called cardioid mic and that’s related to the heart in greek. I think, but it records the sound best that’s, the top of the microphone when the microphone is towards you so currently, i’m speaking into the mic from the front.
This should sound the best. The volume should be the highest now i’m speaking into the microphone from the side. This should be a little less powerful and now i’m speaking into the mic from the rear, and this should have the least volume, as you can see even here on the graph. So this is a low volume and this is a higher volume. Whoo. The lines are much bigger low volume, i’m speaking from behind and now i’m speaking from the front. Okay, let’s. Stop that one. We can unplug that one and here’s the recording itself, let’s record and it’s recording some sound so currently, i’m speaking into the mic from the front. This should sound the best. The volume should be the highest now i’m speaking into the microphone from the side. It should be a little less powerful and now i’m speaking into the mic from the rear, and this should be the least side. This is the most silent part. You have the least volume, as you can see, even here on the graph. So this is a low volume and this is a higher volume. The lights are much bigger, okay, so that’s the microphone test using the smartphone by the way, let’s simulate the artificial wind here’s, a small fan and the battery. So this recording is, with the dead cat on okay and now i’m, going to remove it. This recording is with the dead cat removed. The graph looks identical so let’s.
Listen to this one. I have to unplug this that cat on you can hear the motor okay and now this recording is with the dead cat removed whoa much worse, so that cat makes a huge difference so that’s without the dead cat and that’s with the dead cat.
